Despite DuPont's asserting that "cookware coated with DuPont Teflon non-stick coatings does not contain PFOA", [92] residual PFOA was also detected in finished PTFE products including PTFE cookware (4–75 parts per billion). [88] However, PFOA levels ranged from undetectable (<1.5) to 4.3 parts per billion in a more recent study. [49]
You should at least entertain the idea of abandoning nonstick pans entirely. Thanks in no small part to Bilott's extensive legal efforts, PFOA is no longer used in the production of nonstick cookware.
A 'non-stick surface' is engineered to reduce the ability of other materials to stick to it. Non-sticking cookware is a common application, where the non-stick coating allows food to brown without sticking to the pan. Non-stick is often used to refer to surfaces coated with polytetrafluoroethylene (PTFE), a well-known brand of which is Teflon.
Concerning levels of PFOA have been found in the blood of people who work in or live near factories where the chemical is used, and in people regularly exposed to PFOA-containing products such as some ski waxes and stain-resistant fabric coatings, but non-stick cookware was not found to be a major source of exposure, as the PFOA is burned off ...
While PFOA has been phased out of many nonstick pans, Carignan points out that other forms of PFAS “that lack clear proof of long-term safety” continue to be used to manufacture the cooking ...
PFOA was once commonly used in the production of nonstick coatings — most famously, Teflon, which was invented by the company DuPont and manufactured by its spin-off company Chemours.
