Those are all valid points but a butane flame can go from anywhere between 400°C to 1000°C. To my knowledge no manufacturer has ever disclaimed that their product should be used below 200°C or else fluorinated polymer fumes are released into your kitchen. Downplaying the health impact of those fumes is distracting from the manufacturers' omission. Also we shouldn't defend this with the safety of PTFE in implants, this is misleading because they are completely inert at body temperatures it does not help any discussion regarding the safety a pervasive cookware.

Nobody is downplaying the health impact of overheated non-stick cookware. There just doesn't seem to be much of an impact. Think about this for just a minute. Millions of idiots crank the heat on their cheapo non-stick pans every day. I know people who sear steaks in their nonstick for fucks sake. This has been happening since the 1960's. If there was a significant hazard in this activity, don't you think someone would be able to find it? The fact that cookware makers aren't overly concerned with temperature warnings should tell you something about the health risk here. There is little liability risk to them because apparently there is no demonstrable health risk. At the risk of repeating myself endlessly: > read up on fluorinated polymer fume exposure, you'll find exactly zero known deaths, only a handful of known injuries, and no firm evidence of long term health effects. If you can find any evidence of negative health impacts from nonstick cookware, there are thousands of ambulance-chasing personal injury lawyers who would love to see your work.

The pans I recently bought came with warning about proper temperature ranges. FWIW, William-Sonoma says theirs do too: https://blog.williams-sonoma.com/is-nonstick-safe/ https://blog.williams-sonoma.com/is-nonstick-safe/ I’d bet most people don’t read the directions for their pan, and if they do, they’re probably not measuring the temperature of their pan during use. They’re probably just trying not to burn their butter or smoke their oil, which happens around 200c anyway. And you might have another reason to worry about that food fried at 200c+: many foods cooked at high temperatures themselves form carcinogenic substances.
