We just accidentally baked some trader joes flatbread and didn't notice the oxygen absorber went in the oven with it. If you're unfamiliar, this is the little packet that preserves the food with big words "DO NOT EAT" printed on the side. The packet didn't open, just stayed stuck to the bottom of the flatbread while it baked. However I'm wondering if anything poisonous might have out gassed and been absorbed into the pizza dough? Maybe I'm paranoid, but I don't feel quite safe eating it now.
Oxygen absorber only lists a brand name: AGELESS. From this link its the "ZPT" type. The first one listed on the page.
The flatbread (and the oxygen absorber) was cooked at 425 degrees Fahrenheit for about 10 minutes.
