Warning: Possible problems with new Ziploc bags

Ziploc brand bags have been a go-to for corn allergy people for some time now. Plastics can be an issue for corn allergies, but the particular plastic in ziploc bags was from petroleum and was not dusted or oiled with anything. I personally have been using Ziploc bags for freezer storage, cosmetic and utensil storage, packing while traveling, and even to package my custom processed meat. Well, as it turns out, nothing good can last forever, because there may be an issue with the new version of the Ziploc bags that hit the shelves a few weeks ago.

The new bags have an “easy open tab” and look like this.

In addition to the new closure, the bag itself is a different texture, simultaneously thinner and shinier, and a couple of the very, very sensitive folks have reported reactions to it. One of the people reporting reactions was also the first to notice an issue with the new Ball BPA-free canning lids, so I am minded to heed this warning and exercise caution. Around the same time as people started reporting reactions, i started having some signs of mystery inflammation that started around the same time as I started using the new bags here and there. I also added back the honey that I had run out of for a few weeks that had been safe for me previously around that time, so I have cut them both and will update this post if re-introduction reveals a clear culprit.

For now, I would not panic, just exercise caution with these new bags. If you are in a delicate health state or have delayed or hard to pin reactions, I would not try them until you have your diet otherwise stable so that you don’t get confused about what the cause of any potential issues is.

I have not done any work to contact Ziploc and find out what they say changed or not, I am only reporting reactions at this time. if someone does correspond with Ziploc and wants to post those results here, that would be welcome.

Update Feb 2017: A couple months ago I re-introduced the Big Tab ziploc bags and had esophageal swelling from all food that had been in one. Not safe for me. I can’t be sure if this is a corn issue or not, but they are definitely not okay for me. I have a stockpile of the old-style bags and am moving to glass pyrex or anchor hocking storage containers, mason jars, metal U-Conserve storage containers, and other reusable options  when possible, and Reynolds brand aluminum foil when I absolutely need something disposable.

 

Update June 2017:  I have been using the Ziploc stand & fill slider bags, both the freezer & storage, since last Feb and have been doing great with them. These may be an option for you if the easy-tabs don’t work.

Corny Product Alert: Green Molded Fiber Baskets

I’m making this a separate post from berries or mushrooms, since a number of types of foods could be packaged in these baskets.

Berry baskets- totally full of corn

I have reacted to both berries and mushrooms in containers like this, and there are a number of reports on the Facebook corn allergy group of others reacting to foods packaged in these containers. It is possible that it isn’t the containers but rather the food itself, but I avoid them just in case.

I don’t know what is in them that is so corny. They are supposed to just be “molded fiber” from wood pulp. I guess they must put starches in or something to make them more absorbent of berry juice? Maybe the dye that makes them green? The main manufacturer is a company called Pactiv and the material is specifically called Berigard. I can’t really find information on what these baskets are made from other than “pulp fiber” and why they would be more of a problem than, say, egg cartons, but they really do seem to be an issue for myself and many others.
