PFOA is a surfactant that was previously used for emulsion polymerization of PTFE. It's not found in the finished product. It's since been replaced with other less well studied PFAS surfactants that might be less dangerous or might not, which seems to me an example of bad regulation. It would make more sense to regulate disposal of PFOA, which can be done safely with processes such as supercritical water oxidation.

PTFE itself is about as inert as you can get, assuming it's not overheated. If you use PTFE cookwear, I recommend getting an IR thermometer so you can learn how your cooking setup responds and control the temperature properly.
