Earth Talk: Non-stick cookware dangers

It may be time to upgrade your pans, given that the U.S. government has called for a complete phase-out of polytetrafluorethylene (PTFE, otherwise known as Teflon) and related products by 2015, due to health concerns. When Teflon is exposed to high heat it can degrade, which causes it to release its constituent chemical, PFOA, as a gas. This phenomenon can kill pet birds, and can’t be good for humans either.
