Teflon Legal Resource

In humans, the symptoms of polymer fume fever are similar to that of influenza, but of shorter duration (usually several hours to a couple of days). 

If you get it, don't expect a doctor to recognize it too easily. It is very hard to diagnose, and is hardly ever attributed to PTFE (other polymers have been shown to do more damage). 

Very few instances of harm to humans is known. I could only find one confirmed death from it - a guy that worked in a manufacturing plant that heated PTFE to these temperatures day after day. 

Certainly not the typical level of exposure. 

Based on this information, PTFE may be starting to look dangerous, but my sources all point out that it is totally safe under normal cooking conditions. 

PTFE is used daily by million of people from artifical body parts to naval rings.
