Previous formulations were also claimed to be inert and non-toxic, but were later found not to be. Current ptfe seems to be safe so far but at this point I’m really cynical about safety of these chemicals, industry willingness to inflict them on us and ineffectiveness of governments safety regulations. They’re forever chemicals. Even if they are safe, they will be in the environment, in ever increasing doses, forever. They are accumulating in you, your food, everything you ingest, forever. That doesn’t seem prudent.

What are you going to do if a toxic pattern emerges, but you’ve already incorporated ptfe into your body? even if the the end product is safe, manufacturing chemicals are not: do you accept your part in these toxic forever chemicals?

There’s not much an individual can do, but I can replace non-stick with other materials as they grow older. I have cast iron, stainless, glass, or ceramic as appropriate, that we know lasts longer and will not have a problem.
