Interesting and I thank you for the link smitty55. I don't use it very often (parchment that is, the roll I finished yesterday was likely several years old) but if it is lining a cookie sheet and not direct contact with the food, I would think it still has some value in the kitchen for sure.
I will however rethink my use of it when in direct contact with my food. That being said, there are far more worrisome things imo to be concerned with that can be found in our food supply. But I'm trying to reduce and or eliminate them as I learn about them. Seed oils being a big one for me right now.
