Is that really true? My understanding is that studies show that people with the highest levels of PFAS have increased risk of liver disease. Exactly how much PFAS exposure results in significant risk is still unclear, considering a decent chunk of people eat food from PFAS lined food wrappers, cook in PFAS coated cookware, rub their teeth with PFAS coated dental floss, drink PFAS contaminated water, and touch PFAS coated clothing and other surfaces on a daily basis and do not have any obvious resulting problems.

I'm not saying I disagree that there's a problem, and I personally try to reduce my exposure, but clearly the ratio of usefulness to toxicity is a lot better than with other substances, which have been more tightly controlled in recent history, such as lead and asbestos, and that's why the response has been less urgent. Even now, after decades of study, it isn't clear exactly what the effects are and how likely it is to affect people based on their daily habits.
