We received a question from a visitor to our site this week about the safety of Ziploc® bags for freezing baby food, which we thought would be a good idea to share here.
Mom Gilit had visited our page all about How to Freeze Baby Food.
On that page, we note that some parents have concerns about freezing their babies’ food in regular plastic ice cube trays, as they worry that the trays may contain BPA and potentially affect the food. BPA (bisphenol A) – which has received considerable exposure over recent months – is a chemical used in the manufacture of plastics and which has been linked to a variety of health problems.
In light of these concerns, we suggest on our How to Freeze Baby Food page a few BPA free ice trays that are specifically designed for storing baby food.
However, on the same page we discuss transferring frozen cubes to zip-top bags for storage and Gilit’s concern was that the bags themselves may not be free of BPA.
Well, the good news is that SC Johnson, the company that makes both Ziploc® brand bags and Saran ™ Wrap, states on its website that it does NOT use BPA in the manufacture of these products. This makes Ziploc® bags safe to use for the storage of homemade baby food.
Some parents opt to use zip-top breast milk storage bags to store their baby food. These bags are advertised as being BPA free. Whilst this is another option to consider, you might find breast milk storage bags to be rather expensive compared to ‘regular’ zip-top bags – an expense that really isn’t justified, given the fact that the leading brand zip-top bags are BPA free.

so I guess that would mean it is safe to wash and re-use the bags for freezing? must be as even if the plastic is starting to break down there is no bpa to be worrying about, just freezer burn!

You're right Andrea - the primary concern is with the heating of food. But I think BPA has received such a lot of exposure that parents feel happier avoiding it altogether.

It's good to know that they are safe. Although I thought the problem was only when using plastic with hot/warming food.
