However, we do know that non-stick cookware made with PFOA can leach these potentially harmful chemicals into our kitchens and onto our plates. When heated to high temperatures, coatings can start to disintegrate and send particles into the air, and when scratched and stirred, parts of them can flake off in food.
It’s best to play it safe and avoid the chemical altogether, if not for your own health, for the health of the planet. Since they are created to resist water, oil and grease, PFAS are super persistent and they continue to accumulate rapidly in our environment after being cleaned and washed in the sewers.
The good news is that PFOA has largely been phased out of the manufacture of American cookware. In 2015, eight major chemical manufacturers agreed to sever ties with it through an agreement with the EPA.
However, the perennial chemical can still be found in older cookware and overseas-made cookware (as well as textiles, packaging materials, makeup, and tap water.) As such, building biologist and environmental consultant Ryan Blaser of Test my house recommends getting rid of any old pots that may contain PFOA, especially if they are chipped.
“We want to get rid of them and replace them” with a non-toxic option, he suggests.
