Help! There Are Black Worms in my Baby’s Poo!

We received an e mail earlier this week from Cheow in Singapore who was horrified to find something nasty in her baby’s diaper.

His poo seemed to be full of little black threads. She told us “… they look like worms, but they are not moving. And there are LOTS of them!

Of course, we are not doctors – and it is ALWAYS important to seek medical advice when you have any concerns about your baby.

However, one thing that immediately sprang to mind when Cheow mentioned black worms were – believe it or not – bananas!

Yes, strange though it may seem, eating bananas can lead to the appearance of black, fibrous threads in baby’s poop and – from personal experience – we agree that they do look alarmingly like worms!

This is a harmless and perfectly normal phenomenon – although the black bits may sometimes look more like specks than threads or worms.

We suggested to Cheow that bananas might be the cause and asked if her little boy (Kang) had eaten any recently.

Well, we received another message from Cheow today, telling us…

Kang loves bananas and recently has been eating them up to twice a day. We took him to see the doctor anyway and she agreed that bananas were the cause – in fact, the staff at the hospital thought it was funny that we thought they were worms! Kang hasn’t had any more bananas since we received your reply… and there are no more ‘worms’ in his diaper!

We’re glad you’ve identified the cause, Cheow – although, of course, it’s fine to continue to include bananas in little Kang’s diet.

NOTE: A parent similarly concerned about these ‘worms’ – which turned out to be banana fibres – kindly sent us a photo to help other parents identify them.

After introducing solid foods to baby, there are very noticeable changes in his poop – and they CAN be a little worrying, particularly when you’ve become accustomed to the yellow, almost sweet-smelling poop of the breast fed baby!

Sometimes you may find little bits of undigested food – and some foods may have an extreme effect on the appearance on your baby’s poo – beets, for example, can give it a positively red colour and may even give a pink hue to his pee!

As we mentioned, you should always see your doctor if you are worried – but most of the strange sights you’ll see will be a perfectly normal part of your baby’s transition to solid foods!

Poop talk…

Well, the topics of conversation certainly change when you’re a Mum, don’t they?

But if YOU have ever noticed that a certain food has had an unexpected affect on your baby’s poo, we’d love you to tell us about it by leaving your comments below! That way, other Mums on the verge of introducing a new food to their babies may have a better idea of what they may find in their little one’s diaper as a result!

    Oh thank you !! My 4 month old baby has just started solids this week and he ate a spoonful of mashed up banana on Tuesday. He didn’t have a poo on Tues, Wed or Thurs and when he did go today, his nappy was FULL of the black threadlike things !!! I’ve been worried sick about it all morning and have been searching the internet for information, when I stumbled upon this article – I’m so relieved now – thanks once again . . . .and Thank God ! for the internet !!!

    I’m happy to hear this post helped solve the problem!

  3. Sophie June 17, 2008 at 7:23 am -

    Phew! Thanks loads. I was scared it was blood in her poo but am very relieved as she had banana yesterday for the first time! Just how you describe. What a strange reaction! Thanks very much.

    After reading this I am relief that it may be nothing major. My son did ate a few banana a couple of weeks back, in Brasil. But I have not seen the blackish threads in the poo. He just ate couple of pieces of banana a couple of days ago (in Sao Paulo, Brasil) and now there are those threads and the poo is somewhat runny and mucus like.

    It has been two days now and I was wondering how long does this last.

    By the way, we have given him a few bananas in the past in the USA, but never noticed the threads.

    What a relief! Found lots of black threads/worms in my sons poo and yes he had eaten banana for breakfast. First time I noticed it in such quantity so may just cut down on the portion I give him with his porridge. Useful info, thanks

  8. Suzanne September 18, 2008 at 10:28 am -

    Thanks for this post! I just started my son on bananas yesterday and his poop yesterday and today had them in it so I freaked. Googled it and found your blog, I feel better now πŸ™‚

  10. Kalpana September 26, 2008 at 2:33 pm -

    I was so horrified seeing SO MANY black work like strings in my daughter’s diaper after she ate banana. I took her to the doctor. These doctors are so dumb, they couldn’t tell me what it was, and asked me to come back after 4 days. I came worrying out of doctor office. Basically they want us to go visit them more so that they can get more money. I was relieved when one of my friend told me it could be banana. And when I searched on the internet, I am convinced that it is defintely banana, it cant be anything else. I know what my daughter eats all day. It has to be banana. If anyone out there is worried about the same issue, please relax, its just banana.

  11. Louise October 4, 2008 at 8:18 am -

    What if it’s not banana? My baby’s 5 months old and I saw them in her nappy for the first time yesterday. She has never had any banana. She did have a little bit of pureed apple and peach the day before, and last week she’d had a bad case of constipation for which the doctor prescribed a small dose of a mild laxative (one dose seemed to do the trick), but definitely no banana!

  12. Christine October 4, 2008 at 9:00 am -

    Louise, as we said in our post, we are not doctors so we don’t like to speculate about what might be causing this… it’s just that bananas are a very common culprit and it’s worth knowing that the ‘black worms’ phenomenon can often be triggered by eating them. If your baby has not eaten bananas, then we recommend checking with your doctor to see what is responsible. Please let us know how your little one gets on.

  13. Angeline October 22, 2008 at 3:44 am -

    HI All
    Thank you for all these messages posted! I too freaked out this morning when i saw the thread like black stuff in her poo!
    I also fed her bananas (but only one spoonful)! But at least I am quite convinced now that bananas should be the culprit!

  14. karen October 24, 2008 at 1:06 am -


    My husband and I were freaking out as my baby has just had a poo full of black fibrous threads. There is no way he could have eaten anything other that what we are giving him. We have started weaning with baby rice and banana. We guess that is what it must be!

  15. eve November 9, 2008 at 5:47 pm -

    oh yes! thanks for posting this.. i’m glad it wasn’t what i thought it was… yay!

  16. shereea November 12, 2008 at 8:47 am -

    Thank God i came across your blogg. I too thought that my baby had worms. i have never heard of this reaction before, and havent heard other mums talking about this either. My baby had some banana yesterday which resulted in the black type threads in his poo.

  17. Cindy November 20, 2008 at 11:35 am -

    I must also say thank goodness for this post as I am another mom who just feed my 5 1/2 month old some banana for the first time and was about to call the doctor saying I think my baby girl has worms. Thank you so much.

  18. Christine November 20, 2008 at 12:32 pm -

    You are very welcome! πŸ™‚

  19. Sinead November 21, 2008 at 6:06 pm -

    OMG!!!! Exactly the same thing has just happened to me!! My daughter had banana for the first time this afternoon – my heart was racing while I tried to finish changing her nappy so I could look it up on the net! What a relief!!!!

  20. Veronica January 13, 2009 at 8:12 pm -

    OMG Thank you! My daughter has been eating bananas alot lately and I too googled it and found this blog. I feel much, much better knowing that there are not worms in her poop!

  21. Erinn February 1, 2009 at 3:56 am -

    Thanks a bunch, I was about to take my 5 month old to the emergency room because I thought he had worms (tons of them). He has been eating bananas with his oatmeal, but just recently I gave him a real banana and not baby food. I wonder if there’s a difference.

  22. Christine February 1, 2009 at 9:44 am -

    That’s an interesting point, Erinn – I would imagine that a real banana would be much more likely to cause this reaction than jarred baby food, which goes through more processing. Anyone noticed this type of reaction with jarred baby food?

  23. rebecca February 7, 2009 at 6:31 am -

    My son has had literally millions of black specs in his poo – freaked me out, and I wander if this is from Banana – he has most days from breakfast, should I decrease the amount he is having or even give him a break from it? And why does this happen? It isn’t just from banana it seems others are reporting that it is happening from other fruit as well.

  24. Christine February 7, 2009 at 2:14 pm -

    Rebecca, the specks are likely from the bananas – but, as always, it’s best to check with your doctor if you feel there may be another cause. Although I’d imagine black specks/worms are the result of the way the body processes bananas (and perhaps other fruits too), your doctor may be able to give you a clear explanation as to why this is so! Unless your doctor advises otherwise, there shouldn’t really be any reason to limit bananas in your son’s diet – as we mentioned in our original post, two of our children had the ‘wormy poo’ after eating banana, yet our pediatrician confirmed that this was harmless. Indeed, they carried on eating bananas regularly and eventually the worms no longer appeared!

  26. Elda February 15, 2009 at 1:27 am -

    Christine, Wow! Another grateful person for your blog! My little one ate some banana last week! And just this week started with her “theads in poo” for my life I could not figure out what it was until I found your blog. Whew, Thanks!

    Thanku 4 this site. I just noticed the same in my sons nappy he 6 months n I gave him banana 2day and he had them in his nappy tonite – I was so alarmed until I read this

  29. jea February 27, 2009 at 12:03 pm -

    hi! Thank u for this information. Now I know whats the effect of the bananas to my baby. Thanks! I’m not worried anymore, but I have a question… why is it always hard for my baby to make poo. Can you help me……………

    Hi Christine,
    Thank you very much for your website and your blog too. They’re very useful.

    You’re very welcome Han – I’m glad you’ve found it useful πŸ™‚

  33. Sonja April 15, 2009 at 11:23 pm -

    Hi Christine,

    Thank you! I am so relieved that I found your blog. My 5 1/2 months old daughter had a tiny bit of banana yesterday for the first time and I was freaking out when I changed her diaper today. I wonder what other “surprises” I will find as we continue on with this solid foods journey πŸ™‚

  34. Anna April 20, 2009 at 8:30 am -

    I freaked out when my baby had the same thing yesterday. He is not even 4 months so he has not started on baby food. He is breast fed and formula fed, so on this note I ate a bananna for the first time since I have been breast feeding him, since I am not to fond of bananas. Could the same be true since they supposedly eat everything we do? I have taken him to the doctor and I am just to wait until the next poop to take a sample to the doctor so that they can run some tests. If anything serious I will keep you posted

  35. Christine April 20, 2009 at 9:02 am -

    Anna, we haven’t yet heard from a parent whose baby has experienced this after exclusively breastfeeding – but that certainly doesn’t mean it isn’t possible. Please do let us know what the doctor says

  36. april April 21, 2009 at 1:40 am -

    oh how i love the internet. i just changed my daughters diaper who is one year old. her diaper was filled with little black worm like threads. yes she ate banana yesterday and today. i feel a lot better and can now have a good nights sleep.

  37. Nithya April 27, 2009 at 6:13 am -

    Geez… a big stone lifted off my head. My 7 month old son had his diaper covered with this timy threadlike stuff and i got really scared. have been searching the net and so releived to see your explanation… and yes he did have banana yesterday… thanks a ton…

  38. Han April 28, 2009 at 9:15 pm -

    Hi Christine,
    Thank you for your blog again, I’ve used a lot of your information, your recipies for my son :).
    I have a question about feeding fruit. My son loves to eat fruit and yogurt but he doesn’t love milk or cereal. About a week ago, he quited his bedtime meal. So I’m wondering about giving him fruit or yogurt ( mix with milk ) before bedtime. Is it ok? If it is, which kind of fruits can I give to him?
    Please let me know which is good for him, b/c I’m worried he’ll get hungry if he has the last meal at 5PM ( his bedtime’s about 8PM ).
    Thank you very much!

  39. Christine April 30, 2009 at 9:15 am -

    Han, how old is your little one? Also, when you say he has stopped his bedtime meal, are you referring to a milk feed or a solid feed?

  40. Han April 30, 2009 at 9:41 am -

    My son is 8 month old, since his birth he doesnot like milk even my breast milk. I had to pump the milk for him, and from 6th month, I give him solid food and I have to mix solid food with milk b/c he never drinks milk from bottles ( he only drunk milk when he was sleeping ). Before turning to 8 month, he had 6oz milk at 8pm when he was sleeping but now he doesnot want to drink when sleeping anymore. So I’m kind a worried that he’ll get hungry at night. Please give me your advice.
    Thank a lot!

  41. Christine May 5, 2009 at 12:32 pm -

    So sorry, Han – I’ve only just seen your post. Is your little one’s progress and nutrition being evaluated by a pediatrician?

  42. Lauren May 15, 2009 at 1:04 am -

    Hello! My 5 1/2 month old has just started on solids, and has been on pureed apple for last week, and today and black threadlike bits on her poo… hoping maybe its not just banana that causes this? Thank you for this super useful and relevant blog/site, great to find!

  43. sahra June 4, 2009 at 2:26 pm -

    my 3month-old daughter feeds only on the breast milk but has got small white worm-like creatures. what is it? please help

  44. Christine June 4, 2009 at 3:36 pm -

    Sahra, in this situation it really would be best to get the opinion of your child’s doctor or another medical professional.

  45. Gretchen June 10, 2009 at 9:24 am -

    Oh, beautiful! I’ve seen these things before in my other children, but I just changed my 18 month old’s diaper and found quite a load of these “things.” Since we spent all day yesterday at the park and in a public swimming pool, I was suspecting the worst. However, he did indeed eat bananas yesterday, so I’m feeling pretty confident that is the smoking gun!

  46. Phil June 21, 2009 at 11:12 am -

    Very useful!
    We have just started our 5 month old with some bananas and found the black ‘worms’ I suspected it was the bananas but it was good to read this which has confirmed my suspicions.
    Panic over!

  47. Allison June 22, 2009 at 1:25 pm -

    Thank you so much! I was definitely scared when I saw the black threads in my son’s poop and was about to call the ped. My husband said check the internet and here it was! Thanks again, i will definitely visit this again!

  48. Destinee Chase July 9, 2009 at 3:52 pm -

    This info was so helpful I suspected it to be bananas because i examined the left over baby food that included bananas in the fridge that i made my daughter after noticing the “crazy banana strings” in her diaper. I saw those very fibers in the bowl. They were not black they were light brown and had the same consistency as what was in her diaper. The ones in her diaper were more coiled so they still alarmed me a little. The info on your sight has calmed my soul…thank you.

  49. Adeline July 15, 2009 at 10:12 am -

    Tks so much for your blog info! Really worried to death… when we saw the worm like dark brown stuff in my 4mth old baby. We just gave her, her first semi-solid – mashed bananas yesterday.

    I feel glad that we are sticking to feeding her with 1 kind of food per wk, so that we can be sure what food cause what kind of reaction/allergy.

  50. Caroline July 23, 2009 at 6:33 am -

    Isn’t the internet great! I have just changed my 7 month old son’s nappy and noticed the same black thread like worms, and of course the first thing you think of is dried blood. I am now relieved to read the above blogs, and yes my son also had his first banana yesterday.

  51. April July 30, 2009 at 1:13 am -

    I changed my son’s diaper a little while ago and found white thread like things in his poop. He did eat two bananas today but they are white and not black. The threads aren’t moving but am horrified to even think he might have worms.

  52. Christine July 30, 2009 at 8:40 am -

    April, to be on the safe side I would check this out with your pediatrician. Please let us know the outcome

  53. saidi lefebvre August 6, 2009 at 3:45 pm -

    I’m so glad that I found your web site. I had rush my baby Talor to the doctors because she had black worm like bugs in her diaper and the doctors took the diaper to be sent in and it was bananas. But I was so worried I disinfected my house, called all my friends that I went to, told them to disinfect their houses. And one of my girl friends looked up ‘parasites black worms’, got this site and then called me and said that it was normal. So to all parents – they look like worms but don’t move and there is a lotttt of them and they are black. Saidi Lefebvre

  54. Andreas & Elena August 25, 2009 at 5:46 pm -

    Thank you for your advice, our baby has been eating bananas all this week as he was suffering from diarrhea and doctor suggested bananas as they can cause the opposite effect. Today on our baby’s nappy change we have noticed the brownish little ‘worms’, as we thought they were, but after a 2 hour web searching we came accross your site. Thank you again for your tip! We can also send a microscopic picture of these brownish fibres to anyone that is interested to compare.

  55. JOY August 29, 2009 at 12:08 am -

    Thank you so much!!! I was on the verge of a panic attack, I was examining my 4 mths old poo for hours trying to figure out how she could have worms!!lol

  56. Katie September 5, 2009 at 12:38 pm -

    WOW!! Im sooooo relieved!! Ive just started weaning my little Ryan at 5 Months old, i gave him banana mixed with baby rice this morning and found those lil black threads, im glad its perfectly normal.

    Thanks for the advice!

  57. Eva September 7, 2009 at 11:10 pm -

    I was wondering, why my 4months baby did’nt have that kind of “black Worm” in his poo, but his poo became dark yellow & the smell became very uncommon, after i fed him 1 spoon mashed banana mixed with homemade baby cereal (brown rice). Is it Normal? i was worried & decide for not giving any banana anymore. then go back to baby cereal & sweet potato. within 1 day, his poo turned to be normal.
    is there any clue for this? thx for the advice.

  58. Christine September 8, 2009 at 6:48 am -

    Different foods can certainly produce different looking (and smelling) poos, so it’s likely just the slight change to his diet. However, if you are at all concerned, it’s always best to check with your doctor.

  59. David & Rochelle September 13, 2009 at 8:51 am -

    Just found in my 6 month old baby girls poo had lots of tiny little black “threads” in it.
    Looked like worms, but none were moving and nothing looking like a head, but still concerning.
    A quick look in baby books and a google search didn’t help much, until I delved 3 or 4 pages into the search results (and found this site!).

    Thank you very much for recording this information, as it gives us a little peace of mind.
    Will stop the banana for a few days and see what happens.
    Cheers David.

  60. Kelly September 27, 2009 at 1:36 pm -

    Thank you so much for this post! I too was freaking out about these black specks. VERY relieved I am not alone & that it was caused from a banana! Crazy!

  61. Shital September 28, 2009 at 5:34 pm -

    Thankyou so much.. you dont know how relieved I am to know its nothing but the little piece of banana I gave my son yesterday which resulted in this ugly looking terrifying poo with black threads…

  62. Orli September 30, 2009 at 8:22 pm -

    My baby ate a banana yesterday and today her poop had the thread wormy looking things but instead of being black they were reddish brownish color. I don’t know if it’s cause of the banana. Please help

  63. Christine October 1, 2009 at 11:49 am -

    Orli, I can’t say for sure – and it’s always a good idea to check with your doctor if you’re concerned – but it’s very likely these threads are caused by the banana. As a matter of fact, since this post was originally made, I’ve had ANOTHER baby whose diapers look decidedly wormy after banana – and I would say that the threads do appear brownish in colour at times.

  64. NIcolle October 2, 2009 at 11:06 pm -

    Oh thank God I found ur website..I as most of ur bloggers have said had the same thing these stringy worm like things in bubs nappy after eating banana for a few days. I’m soo relieved to know that banana caused this. Thanks a million a relieved mum :O)

    Hi.. My daughter ate bananas last few days and her poop had black strings and when i searched internet for a reason, found your blog and was relieved after reading it.
    Thanks for the information.

  67. Jessica December 2, 2009 at 8:53 pm -

    Crazy that doctors aren’t better informed about this! I took my 4 month old to the doctor with a diaper full of these black threads, and they sent in lab tests. I disinfected the entire house, got rid of my cats, treated the whole family with hook worm medication… Got lab results after 2 weeks, there were no parasites or ova. Doctor just said that they were probably dead hook worms. Worms showed up again today (first time eating bananas since first incident), but I turned to internet this time instead of docs. I am so relieved! Thank you soooooo much!

    • Christine December 2, 2009 at 10:28 pm -

      You’re welcome – but I’m so sorry you had to go through all that. What a nightmare!

  68. Randa December 6, 2009 at 11:01 pm -

    So familiar! I stopped giving my baby bananas because I realized that it is causing the black threads in her poop. I thought it was some kind of allergic reaction! She loves bananas and I now feel guilty that I stopped giving them to her for more than one month. Now that I know that it’s common, I will definitely give her bananas for breakfast!

  69. Rabbia December 12, 2009 at 2:21 pm -

    Thankyou so much for this post. This afternoon i gave my five months old just one and a half teaspoon of banana. Just an hour ago, when i opened her diaper.. it was full of black strings. The first thing i did was open my laptop to look over the net with one hand and call my baby’s ped for an appointment with the other. Wow! so relieved to see your blog… banana was the culprit :)))

    Thankyou so much πŸ™‚

  70. Ariana December 14, 2009 at 10:06 pm -

    WOW. Same thing happened to me! I opened the diaper and freaked out! I thought she had worms…but they wernt moving. I know my bby girls grandma was giving her mashed bananas..but I wasn’t sure why that would cause worms…so I googled it. lol. And then I found this article. HUGE RELEIF! thanks alot!!What a weird reaction!!I was about to kill my mother in law! lol. Shes always wanting to feed her weird feel so much better now.


  71. Lucy December 15, 2009 at 9:46 pm -

    My little boy, Lucas, has had banana on a few occasions and always had these worm like threads in his poo, but never had them at any other time or with any other fruit. I know with my little boy that it only happens after a banana, he’s had pears and lots of other fruits and never had the worm like threads. Thanx

  72. Emma December 17, 2009 at 6:50 pm -

    I am convinced it is the bananas too. I gave my bub some fresh banana yesterday for the first time. I had her banana-caked bib soaking in a tub and noticed little pink ‘worm like’ things floating on the top of the water this morning – figured it was some fibre from the banana. Then half an hour later changed her nappy and saw the same worm things all through her poo – only black this time. The digestive track must change the colour. Exact same thing though. freaky but interesting.

  73. Mechelle December 30, 2009 at 1:47 pm -

    This is the second day my little girl’s nappy have been full of the black worms!! What had I fed her differently? Bananas of course… Thank you so much for the confirmation and sharing other Mum’s concerns.

  74. Catherine January 3, 2010 at 12:11 am -

    Thank you SO much for this article! I too searched the internet trying to figure out what the heck these tons of brown stringy things were in my 1 year old’s diaper….based on my search I was sure it was either tapeworms or pin worms( but I read these are white in color so I ruled that out) – THEN I stumbled on your article – thank you.

    Quick question – we introduced her to bananas a couple of weeks ago but JUST noticed them in her diaper this evening (she did have a few banana slices this morning) ? Do you know why they just showed up now?

    • Christine January 4, 2010 at 8:32 am -

      Hi Catherine, I’m afraid we don’t have an explanation as to why these ‘worms’ show up at some time and not others, although we’ve noticed the same thing ourselves! Sometimes, it may be that the colour of the rest of the poop is disguising their appearance – we’ve always found them to be more prominent in the early days of introducing solids then, when our babies have a wider menu, we rarely see them!

  75. Ashleyas January 12, 2010 at 5:25 pm -

    Thank goodness! Yes, bananas are the only thing my 7 mo old daughter will eat beside breastmilk. I noticed the fibers yesterday, hers are dark redish/brown wormy-looking, but only occur when she eats bananas. She had them w/ jarred bananas but lighter in color, much more & darker w/ fresh banana. Also have noticed when I eat loads of green veggies, cabbage, spinach, etc and she nurses her poo turns really green. Anyone else notice that? As with the bananas, It’s an interesting phenomenon. So glad I found this site! Thanks πŸ™‚

    WHEW!!! Why don’t they warn us about this in baby food recipe books?!?! Seems like it’s been the cause of a LOT of grey hairs out there!!

    • Christine January 17, 2010 at 6:29 pm -

      Lol – yes, we’ve been amazed by how many people have commented on this post. Hopefully it’s SAVED a few grey hairs πŸ™‚

  77. Allyssa January 19, 2010 at 2:43 pm -

    My son had the `black worms’ too, he had spoonful of bananas for a few days now. I will cut the banana out and see if it goes away. What a relief. I cant thank you enough for this post!!

    I am so glad you posted this! My husband came running in to me with a full diaper, freaked out by the little black threads, and thinking Jose was going to have to go to the ER. I told him to wait until I did some “research” online. Thank god that its only banannas!

  79. Deen January 26, 2010 at 8:46 pm -

    Thank goodness for this posting. I was so disgusted, but thought it was the bananas she ate. Thanks so much for posting this info.

    I’m 23 years old and noticed this stuff recently when I “dropped my kids off at the pool” I was pretty concerned, enough to search and this and other baby sites seem to be the center of this knowledge
    At least I’m not infected with parasites.

  81. Manna January 27, 2010 at 5:55 pm -


    I did gave my 5mnth old mashed banana’s few weeks ago for the first and last time but why these thread like things keep coming till now??

    • Christine January 28, 2010 at 1:22 pm -

      After this period of time, it wouldn’t be the banana causing this – however, other fruits and veggies may have a similar effect. If you are in any doubt, it is better to check with your baby’s doctor – just to be on the safe side.

  82. Sahar January 30, 2010 at 5:06 am -

    I am SO RELAXED after reading this Post πŸ™‚ I gave my 4 months old Baby, Banana for the first time…and he had black worms in his poo too… πŸ™‚ After reading this i am so glad that it is not any thing to worry…

  83. Jackie January 30, 2010 at 5:48 pm -

    So happy to have found this post! Found black threads this evening in my 5 1/2 month old son’s nappy, even my mum – a mother of 5 – didn’t know what it was (knew threadworms are white so didn’t think thats what it was) to have an answer is such a relief – he had bannana yesterday! Thank you.

  84. Michelle February 5, 2010 at 6:37 pm -

    My baby is exclusively breastfed and had this, so it’s not from any food in our case, at least. Almost every baby eats bananas, so of course it’s easy to blame it on them.

    • Christine February 6, 2010 at 9:06 am -

      There may be other causes – which is why we suggest checking with your doctor to be on the safe side – but in the vast majority of cases the banana IS responsible, as it has that stringy, fibrous look when passed in the stool. Michelle, has your doctor given you any idea what it may be in your little one’s case?

  85. aravindh February 6, 2010 at 12:58 pm -

    This blog is useful, but there is no explanation why it happens? Is it a digestion problem? Is it some alergic? Please reply if anybody knows…

  86. Christine February 6, 2010 at 3:11 pm -

    As an earlier ‘commenter’ remarked, these threads are visible in banana itself if you look very closely. It’s likely that they simply pass through baby’s body and come out pretty much the same as they went in (like some other foods!). It certainly doesn’t seem to be caused by a digestive problem and is not, in itself, an allergic reaction. Hope this helps.

  87. CS February 7, 2010 at 11:57 am -

    thank godness I found this blog. I almost freak out when i saw the worm like black threads . I called my friend and she told me it’s normal when they take bananas and i search the web and found this blog which confirms it . Phew what a relief.

  88. Linda February 17, 2010 at 11:46 am -

    Thanks a ton Christine… I am a first time mom and my baby is about to be introduced to solid food. You can imagine how I would freak out when I see black worms like things in her nappy. Now I know what to expect.. What a relief.. Thanks again

    I just had my bub’s stool examined because I saw these thread-like things in her poop a couple of weeks ago. We’ve always given her banana to eat but these black threadlike things only started to show when we visited Manila, so I thought maybe they were worms. Now that I’ve read this I’m thinking it could be banana. I’ll get the results on Tuesday hopefully not worms. Fingers-crossed!

    • Christine February 26, 2010 at 8:21 am -

      We have ours crossed for you too Karen.

    My husband and I were going crazy this morning after we found zillions of black threads in our seven month old’s poo. Our pediatrician prescribed several tests for stool. Luckily I found your site and we are more relaxed now. We just introduced him to bananas two days ago.

    Thank you so much. I was worried sick just now while changing her! Finding this article really calmed me down πŸ™‚

  95. Jannica March 22, 2010 at 6:10 am -

    Hi there,

    I too just found the brown stringy things in my babies diaper, but as the minority (seen two posts describing the same as what I am about to) my baby is still only breastfed. However, the last week or so I have been going crazy on bananas. Could it be that it is passed on through the breast milk?

    • Christine March 22, 2010 at 8:56 am -

      Hi Jannica – as you say, you’re not the only one who has mentioned this after exclusively breastfeeding, so it may be a possibility. I wouldn’t want to say for sure, so it would be a good idea to check with your doctor – in fact, it would be great if you could post back here and let us know what he/she said.

  96. Victoria March 24, 2010 at 11:03 am -

    Hi there, My daughter has never eaten bananas as she is prone to constipation and bananas can aggravate it. She has also had these black threads in her poop and Im sure it’s fiberous foods that cause it.

  97. Prerna Khanna March 28, 2010 at 6:56 am -

    thank u so much for all the informationa and also reading the comments and experiences of all mums with their lil ones having their poop changed after having banana ..i feel so relieved that its normal phenomenon ..THANKS

    • Christine March 28, 2010 at 7:43 am -

      I’m glad it helped set your mind at rest.

  98. Michelle March 28, 2010 at 11:06 pm -

    My son is 2 and has had a lot of bananas and no black string poop. Now he is on Flagyl for possible bowel infection (all test came up neg) and has started having black strings in diaper after eating banana. Could this be a parasite in the banana or just the fiber? Just strange to me that it started happening after we started taking meds for intestinal issues!

  99. Christine March 29, 2010 at 7:33 am -

    I’d guess it’s still banana fiber rather than a parasite – although only your doctor can tell you for sure. I agree it’s strange that you’re only seeing this for the first time since he started the meds… perhaps the color of his stools has changed as a result, making the fibers more visible…? I hope your little one is feeling better soon.

  100. Melanie March 30, 2010 at 2:08 pm -

    OMG, thanks so much. I, too, fed my 5 month old banana yesterday and found the horrifying banana “worms” this morning. Totally freaked out. Whew.

  101. Laura April 4, 2010 at 6:49 pm -

    Ah, thank you, thank you, thank you. I was convinced DS had worms!

    My mother in law gave my daughther banana yesterday, and today her poo had little black worms.

  104. Pallavi G April 15, 2010 at 12:11 pm -

    Thanks a tonne Christine for this post. I have been feeding boiled banana to my 6 month old baby for quite sometime now and was worried about the black threads in her poop and her poop turning dark green in color. Otherwise she is perfectly healthy – socially and physically. She does all her daily activites normally. But still I would let the nurse know about her poop color though – it has turned dark green from regular yellow. Is that because of a virus in the banana?

    • Christine April 15, 2010 at 1:22 pm -

      There can be all sorts of reasons for green poo – certain infant formulas can cause it, as can lots of green leafy vegetables.
      However, green poo can also indicate a medical problem, such as excess iron in the diet or an infection or other intestinal disorder. It really would be a good idea to have it checked out, just to be on the safe side.

  105. Bonnie April 18, 2010 at 9:07 pm -

    so glad i found this site i was freaking out when i seen this in my little guys poop.

  106. Diana April 21, 2010 at 3:48 am -

    Crazy! After I too found black threads in our baby’s diaper tonight, I’ve been frantically searching the Internet for an answer. After (thankfully) finding this blog, I searched again for a reason bananas are causing this reaction. I found an explanation at the UCSF website–the black things are actually the fibrous center of the banana.

  107. Sarah May 6, 2010 at 4:54 pm -

    This was the first link I clicked on after finding black fibers that looks exactly like worms in my babies diaper. We mixed a small amount of mushed banana in his cereal almost a week ago. He hasn’t pooped for DAYS and then when he did, I panicked when I saw the contents. So glad my nerves only lasted for a minute since I found this site immediately. Thank you!

    • Christine May 6, 2010 at 5:16 pm -

      You’re welcome Sarah!

  108. Shaheda May 7, 2010 at 10:03 am -

    Dear Christine,
    I thought to google before going to doctor for these black “worms” – yes they are black and still. I gave my daughter just a small bite of banana day before yesterday. Now, I am relaxed. Thanks a lot Christine.

    My baby was fed banana oatmeal cereal for a week, and her poop has been having these black stringy and grainy stuffs. Suspected it was the banana cereal and stopped for 1 week+, but her poop is still having the black stuffs. Just wondering how long will it last?


    • Christine May 19, 2010 at 10:25 am -

      Is she having any other fruit, June? Although banana is usually the culprit, sometimes fibres from other fruits will also show up in baby poop!

  110. June May 19, 2010 at 10:08 pm -

    She was having pumpkin. But we’ve stopped that for a week now. She’s having anchovies soup + chicken stock porridge now.

  111. Christine May 20, 2010 at 6:48 am -

    Hmm, it’s difficult to say what might be causing it – if you are still seeing this after another day or two then you might want to get it checked out with a doctor to be on the safe side, although I’m sure it’s nothing to worry about.

  112. June May 20, 2010 at 8:26 pm -

    Thanks Christine. I’ve actually made a call to the dr and he assured me that it’s nothing to worry abt as long as there’s no blood in it…
    I just hope it goes away.. πŸ™‚

    • Christine May 21, 2010 at 7:11 am -

      That’s good news June, I’m sure it’ll clear up soon.

  113. Rekha May 29, 2010 at 2:18 pm -

    Hi friends
    My 7 month old baby poo had black worms in it but it was hard and thick I gave her bananas for past two days. would bananas cause hard black stuff in poo?

    • Christine May 31, 2010 at 7:14 am -

      The black bits are typically soft, as they are the undigested fibres of the fruit. It would be a good idea to discuss this with your doctor, just to be on the safe side.

  114. Busy June 1, 2010 at 12:05 pm -

    Thank you so much for this guys. I have too like all those mums above been sick worried after seeing these things in my baby’s poo.
    One more thing I have noticed, if anyone can tell me if they know, were these things that looked exactly like little white beans. and they were squishy. anyone knows anything?

  115. mama June 2, 2010 at 12:31 am -

    Thanks Cristine… you really made me relax.. i saw the same thing in my daughter today and freaked out.. yes i did give her bananas, thank you soo much.

  116. Farida June 7, 2010 at 6:59 am -

    Many many thanks for this useful information….i saw these ‘”worms” 20 days back in my 6 mnths old daughter’s poo and since then i’m sooo worried..i’d hv her stools examined but no results…now i’m sure bananas r the real culprit.

  121. Christine June 22, 2010 at 2:54 pm -

    There’s no need to stop giving them to her, Farida. The ‘worms’ are just fibres and they do not indicate any problem at all πŸ™‚

  124. Enock July 7, 2010 at 6:15 pm -

    Hi thanks for the article,

    We had the same problem with my son, me and my wife were very upset, I had to take a day off to take him to doctors, Doctors wanted to see what the bugs were under microscope,So gave a stool sample for testing, and on the way back to work today, but back of my mind I was very worried about what those worms were, so jumped on the google, saw this article I am so relieved
    My son Loves bananas very much, and was having it all thru the
    week… wonder the results was astonishing……I email the link immediately to my wife to have read……

    Website was very helpful, now I can concentrate on my work.
    Thanks Again…..

    My 1 year old just had a nappy full of these little black worm like things. I was so worried, she has had banana before but just small amounts but yesterday she sat and ate a full banana so this is obviousy the reason for it. So glad i read this or i would have been rushing out to waste my doctors time lol, thank you.

    My 5 1/2 month old just had a nappy full of these little black worms too. Thank you so much for this article I was extremely worried until I finally found this article explaining why they were there!! I had started giving him banana a couple of weeks ago, but it was bottled and he didn’t have any of the little black worms, but recently I have been giving him some fresh banana with his oatmeal cereal which he loves and now he has the little black worms in his nappy. I wonder if there is a difference between the bottled baby food banana and just a mushed up fresh banana??

    Anyways thanks again, I was getting extremely worried, now my mind is at ease and we can go about the rest of our day πŸ™‚

    • Christine July 15, 2010 at 5:32 pm -

      You’re welcome, Crystal. I think the fact that the little fibres don’t show up after jarred banana shows just how processed the banana is (actually, there is a comment earlier in this thread about how the fibres are absent after giving processed banana baby food!). Anyway, I’m glad you’ve found the post helpful πŸ™‚

She ate jar baby food for the last 3 weeks and it’s really fine with her and she liked it a lot.
    But I gave her for the first time 4 teaspoon of mashed fresh banana yesterday, then I search in google and find this blog πŸ™‚ So yes it banana

    I also have feed my 14 month old daughter bananas and noticed the black thread like worms. She has had bananas in the past and never had them in her poo. Now I noticed another post from:

    -on 09 Jul 2008 at 1:50 pm -Patrick-
    -After reading this I am relief that it may be nothing major. My son did ate a few banana a couple of weeks back, in Brasil. But I have not seen the blackish threads in the poo. He just ate couple of pieces of banana a couple of days ago (in Sao Paulo, Brasil) and now there are those threads and the poo is somewhat runny and mucus like. It has been two days now and I was wondering how long does this last. By the way, we have given him a few bananas in the past in the USA, but never noticed the threads.-

    The bananas that I got lately, the sticker said -Product of Brazil-, and bananas that have said for example -Product of China- she has had no problems and no thread like worms from. I’m not saying don’t buy bananas from Brazil, I’m just wondering if I have gotten some bad batches or something.

    • Christine October 14, 2010 at 1:52 pm -

      The thread like substance that most people see is not actually worms, but merely fibrous threads from the flesh of the banana – nothing harmful (although you should always get a doctor to check if you are uncertain). We’re not sure why they can be seen some times more than others – but it’s unlikely there was any problem with the bananas themselves.

  134. Cat October 16, 2010 at 10:36 am -

    What a relief! My son started eating solid foods for the first time this week at six months old. So far he has only eaten fresh bananas. When I was washing a load of his cloth diapers, I noticed tiny black worm-like things and I immediately began worrying that he had gotten worms from our dog who likes to sneak him kisses on the face every chance she gets.

  135. Jean October 21, 2010 at 1:08 pm -

    Great post, thank you a lot!! My 16 month son was having the same thing in the diaper and he had fever right before that (totally irrelevant). I was also suspecting worms or blood and was calling the nurse when I saw your post and now I’m sure that’s what he had, lol. Nurse also confirmed from the phone that there’s nothing I need to worry about. Thank you!

    • Christine October 21, 2010 at 2:25 pm -

  136. Eunice October 28, 2010 at 12:35 am -

    Thank you so much for the website. We noticed 2 black thread-like thingy a month ago when i gave my 4 mth old son a teeny winny bit of banana. We did not really take note then as there were only 2. But yesterday, which was a month later, we found lots of them in his poo and was freaked out. We went to see a chinese physician and she did a massage for him and prescribe 5 days medication for me as I’m breastfeeding. We paid S$200+ for it. Day-light robbery! Should have checked out the website first. Anyway, consider it a lesson learned with a price. Thanks!

    • Christine October 28, 2010 at 5:45 am -

      $200! πŸ™ Oh dear, well at least you’ll know what it is if it happens again.

    Thank you so much for the information.I was so tensed about it.Incidentally,I had my 5 month old daughter’s poop sample tested yesterday and was happy to see the report.Then started on banana for the first time and she loved it!
    but her poop next day petrified me and here i came to browse about it.Thank you once again…Best wishes from a very relieved mum

    What a morning! i gave my 7 1/2 month old baby boy smushed banana’s yesterday for the first time, and today his pamper was full of stringy wormie black things..pheww i was stressing big time..thank you sooo much for posting this blog,i was so concerned and worried i had no clue this was normal..and how long is this suppose to continue on for??? being a mother of three i thought i knew and seen it all,…its weird because my baby was teething and had diahrrea for the last couple of days and they reccomended i gave him smushed banana’s for it,but they never said this was gonna be an outcome….Thank you so much and now i can get back to my day…=)

    I’m so surprised this isn’t common knowledge between moms! Great finding this webpage as I changed my son’s diaper an hour ago and freaked out when I saw the tiny black threads everywhere in his poop. I gave him 1/5 of a banana yesterday, very mashed up.

    This actually confirmed my intentions to make his food at home since it doesn’t show up in jarred/processed bananas (at least not often). It seems this is a natural occurrence and I feel almost glad he had them in his diaper because of the fact.

    My son is 6months old and had those string-like/worm-like thingie in his poop. I had to touch them just to see if those are actually worms. I asked my mum, sister and my maid if they had given him something out of the ordinary to eat in those few days but they said nothing except for ‘banans’ of course which is his favourite food. When I google it up, i was relief to find out what caused it and I laughed to myself and post the blog onto my facebook. Some friends were glad that I shared it with them because the info might come in handy one day!! Thank You!!

    Yes!!! Thank You πŸ™‚ My 5 month old baby girl just started eating bananas about 5 days ago. She hadn’t pooped all week then tonight there was a firm stool with black threads in it. I too was worried it was blood, but am glad to know it’s just from the bananas! Oh the joys of starting solids! πŸ™‚

    • Christine November 26, 2010 at 6:46 am -

      Lol – yes, it’s probably not the last startling poop you’ll see!

  142. Sandra Dust November 29, 2010 at 10:03 pm -

    Pretty awesome article. I just stumbled upon your web-site and wanted to say that I have really enjoyed reading your blog posts. I’ll be subscribing to your feed and I hope you write again shortly!

    OMG I FREAKED OUT all the weekend trying to find out were those “dead worms” in my boys stools. BANANA BANANA BANANA πŸ™‚ He just started eating mashed bananas for breakfast!

    Thanks for this post, i feel much better now πŸ™‚

  144. Tj mummy December 6, 2010 at 6:11 pm -

    1000 thanks for this article.
    i just saw the same in my my 7 months old poo now, i came to google and found this article
    and yes, my baby is eating bananas alot lately

  145. Kell December 17, 2010 at 2:48 pm -

    Thanks so much. My baby was sick the other day throwing up. So when I found these little ‘black threads’ in his poop. It had me REALLY worried. Yes! I even touched them to see if they would move. As I was cleaning out his cloth diaper just now I kinda took a closer look. And it reminded me of the little ‘black threads’ in banana bread. The only thing he’s been eating since he was sick was bananas. So I wondered and hoped it was from that. So THANKS for the article!

  146. Lana December 24, 2010 at 6:28 pm -

    Is there any way to post a photo? I think that would help other mommas (and dads!) out there as well. I have one if you want to use it.

    • Christine December 26, 2010 at 9:26 am -

      Hi Lana, I have emailed you with instructions for sending in a photo – thank you

  147. Christine December 28, 2010 at 8:32 am -

    Thank you Lana – our post now contains a link to your photo.

  148. Lana December 28, 2010 at 9:10 pm -

    Okay, good, hopefully it is helpful. The reason that we took the photo is so that I could magnify it on the computer for a closer look. To the naked eye they kind of looked more like little threads. Once I took the photo on a macro setting with our digital camera I about had a heart attack! They looked more like worms or parasites or something – definitely not threads! I was relieved to find this information (that it is from bananas and not an issue) online, especially seeing as how it was Christmas Eve and I was picturing us in the ER or at Urgent Care! Thanks for the helpful post. :]

  149. shaunel December 28, 2010 at 9:58 pm -

    THANK YOU this is great same story iv been worried sick was gonna take her to the doctors tomorrow but i wont now. you’d think more people would know about this as it seems to happen alot!!! x

  150. Christine December 29, 2010 at 8:07 am -

    You’re welcome Lana and Shaunel – and yes, this does seem to happen a lot. It’s a pity bananas don’t come with a little warning, as one parent commented!

  151. Sowmya January 2, 2011 at 2:30 pm -

    Thank you..I gussed the same with my 6 month old and your article confirmed it. My son is a little guy and I thought bananas can add calories to him, but I think I wil have to remove from his diet now. Is there any alternate to avoid the strands? Btw he loves bananas and apple mix puree.. Pls help.

    • Christine January 2, 2011 at 3:38 pm -

      Hi Sowmya – there’s no need to stop feeding your son bananas – they’re a wonderful food! The strands aren’t harmful at all, they are merely the visible fibres from the fruit.

  152. deanna January 26, 2011 at 9:37 pm -

    omg this helped me too >< i was so scared it was something terribly worse but he just had banana the other day so ty!

  153. Mary January 27, 2011 at 8:01 pm -

    Searched baby stool with black strings and this came up. I was so scared when I looked at his diaper today it was filled with what looked like black strings and I never saw that before. This puts me at ease because he did have pieces of banana yesterday. He also isn’t feeling well so I’m going to show the Dr. his diaper just to be sure but this site was very helpful to ease my mind for now. Thank you!

    • Christine January 27, 2011 at 10:51 pm -

      Happy it helped πŸ™‚

  154. sarwan February 10, 2011 at 7:52 am -

    hi Chris

    Im so glad for ur post. Just now my lo 4m 3w passed poop which had black worms kind of. I was frightened to c that. dont know wat to do. thank god i searched in internet n got ur post πŸ™‚ s lo had just tasted banana 2 days before n didnt pass poop yesterday n today this happened. ufffff im so relaxed now. so do i need to continue giving her banana r i hv to speak with my HW?

    • Christine February 10, 2011 at 10:00 am -

      You can continue with the banana Sarwan, the threads are fibre from the banana and don’t indicate a problem.

  155. Karina February 10, 2011 at 4:25 pm -

    Thank you!!!! Was scared out of my mind.

  156. Gemma February 14, 2011 at 8:39 am -

    PHEW, so glad i found this discussion!!! he had banana yesterday so defo convinced its that!!

  157. Kali February 19, 2011 at 8:46 pm -

    I am so much thankful that i have found this site! My baby pooped twice with black string-like things. there were LOTS of them! I was scared to death! all along i thought those were parasites in my 6 month old baby’s tummy! I remembered he’s eaten mashed banana’s before he had that kind of poop. now my mind is free of worries! i was supposed to bring him to his pedia yesterday but we were late and wasn’t able to had a check-up. Thanks for the very helpful info!

    • Christine February 19, 2011 at 9:13 pm -

      So glad it helped πŸ™‚

  158. Shannon February 27, 2011 at 1:02 am -

    I was wondering that too. just got home and changed my 4 month old daughter, and she has black threadlike things. I thought worms right away two, especially since we have dogs. She doesn’t eat baby food yet, but I did have a banana yesterday. I’m going to call the pediatrician just in case but I do feel better having read this post.

  159. Jagdeep March 14, 2011 at 3:04 pm -

    This is post do helped me to relieve in short time. It happened to my child today and I was madly looking for a worm kind of stuff. But instead I find this post and free of fear. Perhaps this is due to Iron in the banana.

  160. mary March 18, 2011 at 10:29 pm -

    thank u for this blog. im so relieved bcoz my 10months old daughtr loves banana and i noticed the tiny black thread in her stool and thought it was worm.

  161. debra rishmawi March 21, 2011 at 6:33 am -

    Bananas! Yes, they do this. But in my experience (I have 3 children) other fruits do this as well. Banannas are certainly in the lead for the quanity of black “threads” but apples and peaches have created this as well with my children. Kinda gross but worth it for the benefit of eating fruit!

  162. lory March 25, 2011 at 11:39 pm -

    my 6 mnth 3wk daughter has been eatn gerber food since she was 4 n a half mnths n poopd like tht today she is eatn gerber
    foods but 2 days ago she had a stomach ache n puked really
    bad it evn came out her nose, and she hasn eatn any bby food
    (for bout a wk) n she poopd bout 4 times today b4 the
    black lookn worms showd up, so since shes only had bottle for the wk (No bananas for bout a wk n a half) wht cld it b or is it still jus the banana new food

    • Christine March 26, 2011 at 6:52 am -

      Lory, it’s difficult to say, although I think it’s unlikely to be the banana after 1 1/2 weeks. I’d suggest taking her to the doctor to establish the cause of both this and the vomiting – please let us know how she gets on.

  163. simone March 26, 2011 at 11:12 am -

    WOW, this is exactly what I thought about my baby’s poop today!!!! Wouldn’t you know it, I gave him a small amount of banana yesterday! THANK YOU!!!

  164. Ishita March 31, 2011 at 4:34 am -

    Thanks Christine.
    My baby girl is 5 + months old , to day morning i was tensed to see black thread like worms with gree poo in the diaper. i started searching in net , got this article and was really relaxed , i was giving banana for last 2 days to her. now i understood who is the real worm!!!

  165. Raya Salaam April 3, 2011 at 2:24 pm -

    Thank you so much for posting this! I am a first time mom and nearly flipped my wig when i saw these “worms” in my babies diaper!!

  166. lisa April 15, 2011 at 5:34 am -

    oh my god i nearly died just now thank god its nothing to worry about how strange bananas can cause such scares defo no what it is next time my little munchkins has them

  167. saba April 16, 2011 at 1:41 pm -

    my lil one 9mnths 10days old baby boy is passing stools with large no of black immovable threads black in colour ………..are these worms?
    he is taking small banana pieces mixed wid biscuits nd cereial…..can this b the cause?

    • Christine April 16, 2011 at 2:47 pm -

      It is much more likely to be the banana than worms – please do read through the comments above and check out the photo, but if you’re still concerned, then of course have a doctor check him out.

  168. Sumit April 18, 2011 at 1:25 pm -

    Thank God I found this thread. We were scared to see our son’s diaper full of these black threads and took them as worms. Our son ate banana 3 days ago and hasn’t pooped since then till a few minutes ago. We’re so glad we found this thread. Thanks Christine !

  169. kelly May 23, 2011 at 6:36 am -

    hi my son is 20 weeks old has black bits in poo but has never eaten banna what could be the cause thanks

    • Christine May 23, 2011 at 11:44 am -

      It could be fibers from another fruit/veg – however, you should see a doctor for a proper diagnosis, just to be on the safe side.

  170. Megan June 5, 2011 at 1:08 am -

    Oh!!! This is such a relief. My little one started on some bananas a few days ago And this morning had those litte black stringy things in her poo. I was pretty frightened and they kept appearing in every diaper. Decided to check on the net.thank goodness for this site. I can sleep better tonight.

  171. Nazish June 17, 2011 at 6:47 am -

    This is a good forum to share stuff and ask questions related to your baby. My son is 6 months old and at times does poo after 2 or 3 days. Is it alrite giving this much gap?

    Thanx & Regards

    • Christine June 17, 2011 at 6:53 am -

      It’s more common that you might think for babies to go a few days between poos – the main issue is that your little one can poo comfortably when he DOES go (in other words, his stools are soft and he isn’t straining). If you have any concerns, it’s always a good idea to check with your doctor.

  172. smile June 17, 2011 at 6:20 pm -

    Thanks so much for this information. My 6 month old son had 2 spoons of fresh mashed banana yesterday and I found hundreds of black thready things in his diaper today. I was so scared and I called the doctor. Surprisingly they dont know about it. Good that I found this thread!!

    Can I continue to give him banana or shall I stop for some time?

    • Christine June 18, 2011 at 8:37 am -

      It should be fine to continue, as the ‘threads’ are merely undigested fibres from the banana and are not at all harmful or suggestive of a problem – but if you’re in any doubt or at all worried, then please do check with your doctor.

  173. Parvina July 1, 2011 at 10:37 am -

    Thank you! That is relieved me.

    just all this happend to my 10 months old son … i was sooo much worried n thought to take him to the doctor in the evening .. but after searching it on google i found ur blog.. relaxed now .. coz 1st time he ate half banana yesterday n it must be the cause πŸ™‚ infact i gave him jars as well but it was 1st time that i hav seen black small thread in his poop .. anyways it was really helpful 2 be here n im much relaxed now πŸ™‚

  176. winnie July 16, 2011 at 6:04 am -

  177. Mary July 22, 2011 at 9:29 am -

    Thank Goodness, I gave my 5 and ahalf month son banana for the first time yesterday, and this morning he had black bits in his poo, couldn’t decide whether it was worms or fiber, but to me it looked like fiber and I was begining to worry about what he may have put into s mouth. Was also a bit worried that I started weening him too early because over here in the UK its not recommened to start weening until 6 months. Reading this blog has certainly given me peace of mind so thanks.

  178. Sweety.k July 23, 2011 at 4:19 pm -

    Hey hi to all.Thank u all for these helpful answers,ive conceived after 6 yrs n My baby is precious to me,He is four months old n ive been feeding him Banana since 2 days and after two days i see these black worm like thing in his poo,now i feel relaxed and happy that this is a common thing in babies.Thank u all.

  179. Laura August 2, 2011 at 2:00 pm -

    Thank you! My mother-in-law fed my son banana yesterday for the first time (without my consent) and my husband and I almost died when we saw the black “worms” in his poop last night AND this morning.

      Happy to help!

  183. Jen October 26, 2011 at 1:56 pm -

    When we see these little fibers in their poop or other pieces of food does this mean their little tummy is not ready for solids just yet? Eventually we won’t see any fibers right?

    • Christine October 26, 2011 at 2:40 pm -

      It doesn’t necessarily mean they’re not ready – their bodies are simply passing out the indigestible fibers. You may not see them later on as you probably won’t be checking as thoroughly lol!

  184. Jen October 26, 2011 at 3:05 pm -

    Haha, so true! Thanks for your quick response and wonderful website!!

  185. Christine October 26, 2011 at 5:00 pm -

  186. Suha November 3, 2011 at 1:46 pm -

    Thank you for this info.. my hosp didnt know what it was i was talking about..& my doc’s out of station πŸ™‚ my 6 month old started on bananas a few days ago and am so glad to have found this blog . But the last 3 days the thread like things are red in colour.. like saffron threads instead of black… what could be the cause.. i know they r not worms.. just red version of the black fibers that started once she started on bananas. any idea?

    • Christine November 4, 2011 at 6:04 am -

      They could still be caused by fibers in the banana, Suha – some parents have said that they look reddish brown in colour. They may also be caused by another type of fiber-rich food – is your baby eating anything else? My guess, however, is that the bananas are the culprit – but, as always, if you’re concerned you might want to ask your doctor to check it out on his/her return.

  187. Roz November 12, 2011 at 6:16 pm -

    Just experienced the same exact thing and freaked!!! I instantly called his dad and rushed him home so he could inspect our son’s diaper ;P This article saved me from a heart attack =) THANKS EVERYONE!!

  189. Ivy November 16, 2011 at 5:30 pm -

    Whew! I’m glad to have found this article.. I was worried to see the black threads on my baby’s poop too! Now we know that its because of the banana that he ate yesterday.

  190. Sarah November 22, 2011 at 6:55 am -

    this article has been helpful. just found black spots in his green colour poop. gave him banana for the first time yesterday.

  191. irfan December 9, 2011 at 4:17 pm -

    my 5 months baby boy poo colour is black and yello mix and his bottle feed baby i give his regulary one little apple juice (home mad)
    about 2 once mix with half amount of water totl abot 4 once this is cause to my baby poo is black this is normal other wise i concern dr plz give me a answer as soon as possible

  192. Christine December 9, 2011 at 4:44 pm -

    I’m sorry Irfan but we really can’t answer this – it would be best to have it checked by a doctor to be sure of the cause. Sorry we can’t be more helpful but it’s better to be on the safe side.

  193. Jay December 18, 2011 at 10:58 am -

    My son ate some bananas and he has been pooping every 2 to 3 hours, and he has a rumble in his tummy…

  194. Sarah December 28, 2011 at 10:30 pm -

    My 5 month old has also had this in her last dirty diaper….so relieved! She has had some bad tummy aches as well and lots of stinky gas! She mostly has eaten avacado as her 1st food with a bit of banana here and there. We have had many sleepless nights….waking and then passing gas. Do you think these foods could cause this? She is also teething 3 teeth at once…so we are dealing with a lot of differint things here.

    • Christine December 29, 2011 at 6:46 am -

      Poor little baby! Although banana and avocado don’t seem to commonly cause gas in babies, it’s possible that they don’t agree with your little one. But – as you say – you’re dealing with several issues simultaneously – our babies always seemed to have upset tummies when they were teething! Another thought… are you breast feeding? Is it possible that she might be reacting to something YOU are eating?

  195. Sangeetha January 4, 2012 at 2:58 pm -

    Thank god….. I got an answer for the black threads(worms) in my little darling poo poo.. I just started with banana n found the same probs.

  196. christina January 16, 2012 at 3:43 pm -

    My baby is only 2 months old and is strictly breast fed. He is allergic to dairy, and I have been avoiding it for quite a while now. Today he had a ton of mucous in his diaper, and little black thread like strings and particles. This is not from bananas as he has never had bananas. I did give him an ounce of apple juice in a bottle a couple hours before he pooped because he seemed to be struggling to have a bowel movement. I really don’t want to take him the the ped. b/c his ped. told me not to worry unless I see blood in his stool. Please advise if possible. Thank you.

    • Christine January 16, 2012 at 4:52 pm -

      Christina, I completely understand how you feel about asking the ped, but I’d still recommend that you do so as your baby is so young and I’d hate to dismiss anything that might be significant. The mucous/threads may be completely unconnected to your baby’s allergy and your ped is the best person to advise – so sorry not to be more helpful but it’s really important that your doctor rule out any underlying problems. Please do let us know how you get on. x

  197. ciaran January 21, 2012 at 12:45 pm -

    Just changed 6 month year old nappy and saw the ‘worms’. They are so convincing and because our little one has been poorly of late, I was worried it may have been something more sinister. Rather than calling the doc, I googled and found your link. Instantly feel better as I know my wife has introduced bannanas of late. I want to thank you for your sire & work!! Reassured parent.

    • Christine January 21, 2012 at 3:15 pm -

      You are VERY welcome – and thank YOU for your comment. I’m so pleased that this post eased your mind πŸ™‚

  198. Katherine January 22, 2012 at 12:11 pm -

    Oh – lol – I was so worried she might be having a reaction to the bananas I fed her – my four month old has eaten bananas twice in the last week and both times ended up with a HUGE mess of BLACK BLACK poo – now I know that’s normal …. I feel silly for freaking out!

  199. Ava January 22, 2012 at 9:59 pm -

    Katherine, never hurts to check with doc though, you know? I have a 4 month old, too! Looked like she had black paint chips in her poop, very odd sight! I bought jarred baby food for my first two kids, this is my first time making my own baby food. Never saw this with her older siblings, I wasn’t prepared, haha!

  200. samantha February 2, 2012 at 12:21 pm -

    Just quickly dashed on computer to search for baby poo!! as my lil bubba left me with a greeny speckled dirty nappy!! reassurred now as he did have fresh banana yesterday… so thanks to all who left info on here πŸ™‚

  201. hazel February 4, 2012 at 11:03 am -

    dear all,

    thanks everyone! i discovered the same in my 5 month old baby who has been eating banana for the past 2 days. i emailed her pedia dr. and she said its normal. i just have to continue observing if there is more strange stuff other than the one i noticed.

    i freaked out and was not able to sleep last night. thanks for this info.

    tomorrow she will start eating apple. if there is some expected odd appearance in her stool, i would be very glad if you let me know so i won’t freak out the 2nd time.

    thank you.

    • Christine February 4, 2012 at 4:02 pm -

      Although it’s FAR less likely, you can sometimes see the little ‘thread’s after apple or even other fruits/veg. It’s simply the fiber but seems much more noticeable after banana.

  202. Alison February 22, 2012 at 9:41 am -

    Oh my goodness!!! Did I panic when I saw my little ones nappy! Went straight to the computer and found the answer here. Thank you for putting my mind at rest!

  203. Jenn February 23, 2012 at 10:27 am -

    I was so worried when I changed my 6.5 month old ds’ diaper and it was full of black flecks! So thankful I found this site as I gave him 2 servings of home made banana baby food yesterday for the first time! Thank you for this article!

    Thanks for this.. i freaked at first on seeing my baby’s poop but calmed down to see it was just the bananas he ate yesterday

  206. Terese March 18, 2012 at 10:07 am -

    Wow.. I am so glad to have seen this information because I just saw this in my 5 month old daughter’s poop. It freaked me out and I just left a message with the doctor. And she did just eat bananas within the past few days. It was a site to see and I did take a picture and its clearer then the one I saw on here. I mean it was all over …. Thanks for the info and if you would like to see the picture I can sure send it. The things that the body responds to in these ways are something.. Thank God it wasnt worms…lmbo!

    • Christine March 18, 2012 at 11:43 am -

      Thank you Terese – we’ve contacted you regarding the photo, which we’re sure other parents will find useful πŸ™‚

    I started banana to my three months old baby .after that when I change his diaper I was surprised to see black threats in poop I check from computer now I am satisfied to know that it is due to banana

  208. lucy March 29, 2012 at 12:53 pm -

    i started giving my 4.5 month baby girl banana. started getting worried when i seen black threads in her stool. thank u everyone my minds now at rest

    I’m sooooo releaved. Harrison is 21/2 and has had bananas lots of time before but has only just started having thread / worm like black bits in his poo. It has reassured me a lot reading everyone else’s experiences. Thank you!

    Hello, I’m a first time dad and we experienced the same. My wife freaked out and quickly got OTC worm medication. However, being that I’m a medical doctor I was sure they weren’t worms as I already knew all human worms. I kept asking after our baby’s recent foods and thankfully, I came across this.
    Thank you very much guys, you really helped calm my wife down.

    phew! thanks to this article. i was relief when i read this because my baby’s poop have those “worms”, too. oh well, my baby’s eating baby cereal in milk and banana flavor. that’s what explains the existence of “worms” in my baby’s poop. πŸ˜‰

    • Homemade Baby Food Recipes June 19, 2012 at 8:25 am -

      Β @techiegirl23 Just checking – your baby did eat actual banana, rather than banana ‘flavoured’ cereal? It’s just that the ‘worms’ are fibres from the fresh banana, so baby would have had to have eaten fresh banana for them to be present.

      • techiegirl23 June 22, 2012 at 8:45 am -

        @Homemade Baby Food Recipes
        just a litTle amOunt. so you mean even a litTle amOunt of fresh bAnana may pRoduce numbers of “worms” in my bAby’s poOp? becAuse she just tasteD a bit. buT riGht nOw i knew that those are just bAnana fibres becAuse of the photos sent by other mOms. thanks to them, toO.

        • Homemade Baby Food Recipes June 22, 2012 at 1:31 pm -

          Β @techiegirl23Β Β @HomemadeΒ  Yes, a little banana could produce this result – I was just checking that it was ACTUAL fresh banana she’d had, rather than a banana flavoured product (which would not contain fresh banana). It seems that she DID indeed have banana, so yes, those ‘worms’ you’re seeing are the fibres.

    Omg! I calmed down completely, after reading this article and seeing pics….I was freaked out and never saw anything like this before not even in my first born. My Β 6 month old son had recently been eating bananas, and I thought he had parasites or something worse. I was confused because he wasn’t acting any different and his eating/sleeping habits didn’t change either. Babies aren’t timid to let moms and dads know, “Help me! I’m not comfortable!” LOL Β

    I saw the ‘worms’ and freaked out too until the doctor told me (over the phone) it was likely banana. However… I gave the baby about an inch of banana on Monday and now it is Saturday and the ‘worms’ are as numerous as ever. Why would her poop still have banana-anything in it 5 days later if she hasn’t eaten any more banana? By the way… the inch of banana was her first solid food and the advise nurse scolded me for giving my child, who turns 6 months old Monday, solids at 5 months and 3 weeks.

    Wow, so earlier today I let my two year old son play in tub and while I was getting a towel out of cabinet he decided to poop in the tub. I got him dressed and was letting all water drain from tub and when I went back to clean it up I seen tons of small little black threaded worm looking things connected to his poop and I freaked out thinking he had worms (thought only animals got worms lol). I’ve never noticed them before when I give him banana ???? but its been a while he ate 3 yesterday and two today he is a lil monkey. I literally was gonna wake him up n rush him to hospital, but looked this up first and now I’m thinking its just the bananas thank goodness ????

    I had a similar experience with avocado. My daughter (5 months) ate avocado and had the same stringy things that were described from the banana. Good to hear it can be normal.

    I have been so troubled by the ‘insect like’ appearance on my Son’s poop this morning. Since he had a tummy ache i had drawn my conclusion for worms. I thought about the effects of bananas, since he loves it and yesterday he had the bigger type (Locally known as Bogoya) yet i could comprehend with what i saw. I am so glad for this article, my heart is now at rest. Once again, Thanks

  265. Riya July 22, 2017 at 8:43 am -

    I exclusively breast feed my 3 month old. Today I notice brown string like things in her poop. I ate banana today after long time. I hope it’s from that. I saw one of the mom”s post (Anna) with similar concern , she said she would update . Unfortunately i couldn’t find her post, it was few years back post. Tomorrow I am going to talk to my baby’s doctor to find out the reason.

    Thank for this post! I am little bit relieved.

    thank you so much for this article & the picture! My 5 month old had these black strings in her poop yesterday, I took a picture of the diaper & brought her to the doctor but they couldn’t give me any answers. She had banana the day before & before I googled it I thought to myself it could be the banana, but to know that other parents have gone through this & reading the comments now I’m sure it was the banana. My mind is now at ease, I was so worried! & Even though it’s gross to some people, having a picture to compare it to is a huge help! My babies diaper looked exactly like the picture
