I used a different source than the one you link. 500F is not difficult for a frying pan to reach either.
The same Wikipedia page also reads:
>Pyrolysis of PTFE is detectable at 200 °C (392 °F), and it evolves several fluorocarbon gases and a sublimate.
My completely unscientific, unsubstantiated guess, based purely on obsessively researching food safety for years, is that it begins to leach at a much lower temperature.

Most vegetable oils smoke before 500F. If you're just frying up an egg or sauteing some vegetables you'll be fine.

The sentence after it:
>An animal study conducted in 1955 concluded that it is unlikely that these products would be generated in amounts significant to health at temperatures below 250 °C (482 °F).[
Without reading that study, who it was funded by, how it was conducted, I choose to err on the side of caution. In other words, I don't believe that statement for a microsecond, especially coming from 1955.
>While PTFE is stable and nontoxic at lower temperatures, it begins to deteriorate after the temperature of cookware reaches about 260 °C (500 °F),
