At high temperatures, PTFE can release toxic fumes that can cause something called "polymer fume fever" (no joke, that's a real thing!). Symptoms include headaches, fever, and chills - not exactly what you want to get from cooking up a storm in the kitchen. But, before you start imagining a toxic nightmare, let's look at the facts.
It's worth noting that T Fal, like many other manufacturers, has started to phase out PTFE in favor of newer, safer coatings like ceramic and silicone. These alternatives are non-toxic and PFOA-free (that's perfluorooctanoic acid, for you chemistry buffs!), making them a better choice for cooking up a healthy storm.
Now, before you go pan-demonium and toss your T Fal pan in the trash, remember that the risks are relatively low if you use your pan correctly. Just avoid heating it to crazy-high temperatures (we're talking above 500°F), and never leave it unattended - you know, the usual common sense stuff.
