I got a little more time to respond today so here it is. Perhaps leading brands such as Saran Wrap are safe now
if used properly. My concern is using off brands that may still contain harmful additives such as plastizers and/or uninformed misuse.
Here's a reputable link:
Note the following:
Phthalates and the Types of Products They are Used In
Di (2-ethylhexyl) phthalate [DEHP]: building products, food packaging, children's products and medical devices DEHP is added to PVC to make some soft, clingy wraps for commercial use. Consumer Reports tested 14 national and local brands of wrapped cheese for levels of plasticizers. The reason they chose cheese is that plasticizers are more likely to leach into fatty foods like cheese and hamburger. They found high levels of DEHP in the cheeses wrapped in deli cling wrap. People who eat several ounces of this cheese every day could get very high doses of DEHP that could possibly cause health problems. There were moderate levels of DEHP in some of the shrink-wrapped cheeses and in the waxed cheeses with plastic overwrap. There was little or no DEHP on individually wrapped slices of American cheese or blocks of cheddar in laminated foil wrap. Consumer Reports also tested plastic wrap. Of the seven national and store brands of plastic wrap they analyzed, only two contained any of the five plasticizers they were looking for. They reheated a cooked hamburger wrapped in those plastic wraps, but found just a little bit of the plasticizers had been absorbed where the patty was in contact with the wrap. In terms of the eight microwavable bowls from top manufacturers they examined, they found no plasticizers.
I believe in a relatively minimalist approach in cooking. Consequently, I don't wrap. I think it's generally a waste of time and finite resources that end up as garbage. This is my personal choice and I don't intend to force such views on anyone else.
Another personal trait of mine is a general mistrust of agencies such as the EPA in safeguarding the public health. In my opinion, such agencies have often been shown to be too cozy with "industry" instead.
Also note my byline: "A thin line separates paranoia from an acute understanding of reality." I could be straying over that line a little here but then again, maybe not.
