The following are known: 1) high temperature can cause degradation of PTEF and producing hazardous fume 2) PFOA used in the production process of PTEF is a suspect carcinogen to humans.
1) is easy to control by managing cooking process 2) is a bit tough.
In my search for a better non-stick pan, I found Scanpan from Denmark. Quite a few cookware sites carry them, but not common in department stores. Its website states that their products are free of PFOA.
Scanpan's non-stick pans also use PTFE, but it developed a unique surface treatment process to greatly strengthen the binding of the non-stick coating with a hardened aluminium surface. As a result, you can use metal utensils on them without causing chipping.
"The Scanpan nonstick cookware lines use a coating process that consists of a ceramic-titanium plasma blasted onto the surface of forged aluminum, resulting in a surface with a hardness of 9.5. Nothing in your kitchen, other than your diamond ring, can scratch it. The surface of SCANPAN cookware is a uniform array of microscopic pits that are then filled with a high-temperature nonstick coating, out of the reach of metal implements and thus not subject to abrasion."
I've had Scanpan products over a yr now, and we use the frying pans daily. The surfaces don't have a single scratch mark after that much use, and as non-stick as when new. They work very well, for cooking egg, fish and pancake.
We don't use them in high heat cooking, to avoid any issue with PTFE.
They're somewhat pricey, Amazon has good price on the 9inch frying pan.
Hope the above helps, the following contains more price info on them.
