Heres the deal with Teflon. Teflon is a polymer of TFE, called PTFE. The one above is 5 molecules of Tetrafluoroethylene. This polymer can be as long of a chain or as short of a chain as you want it to be. PTFE will not enter the air as fumes as most people believe. It is way too heavy of a molecule for that. TFE is the result of overheating PTFE and is the toxic chemical that everyone is concerned about. It is much lighter and passes through the air as gas very readily. This molecule is a CFC (Chlorofluorocarbon) and was originally being studied as a refrigerant. Everyone here knows that CFCs are very toxic and have been advised against for many many years. PTFE, the polymer, thus-far has no "confirmed" side effects. This is where the confusion comes in. Many articles have been written incorrectly and call TFE the polymer form PTFE. This is the problem with reading articles on the internet. Anyone can publish an article on the internet with no consequence to them if the information is wrong. It is best to stick to .gov and .edu publications, as well as peer reviewed articles. I would suggest the American Chemical Society (ACS) for publications on this matter.
Now, I read the article "Silent Killer" and it is a good example of misinformation. The first thing that struck me was the incorrect spelling of the chemical name Polytetrafluoroethylene (in the article it was spelled Polytetraflouethylene). It is also incorrectly referred to as Teflon fumes. Another mistake in the article is that Teflon will fumigate at 285 Degrees.... Now most people would automatically assume that this is 285 Degrees Fahrenheit. The actual number is 285 Degrees Celsius, or about 550 Degrees Fahrenheit. The funny thing is that this figure actually came from an article by DuPont themselves in 2000 and was not translated correctly in other articles, hence all of the commotion about the lower temperature causing harmful fumes.
Believe it or not, a pan can reach temperatures of over 720 Degrees Fahrenheit on an electric burner set on high in just 10 minutes. This is easily enough to release harmful fumes. Certain light bulbs especially Halogen can have a very high surface temperature that may cause the release of TFE. Also Halogen bulbs can release UV spectrum light which is suspected to be a catalyst to PTFE chain breaking.
So whats my take on all of this? Absolutely do not cook on Teflon pans when you have a bird. Its not worth the risk! While you may be able to get away with it at low heats, the risk is still there and very real. Also don't use Teflon coated bulbs near your bird. Thats also not worth the risk.
I really want to also stress that the internet can be a useful tool for obtaining knowledge, but it is also the biggest spreader of misinformation. Remember to stick to .gov, .edu and peer reviewed articles for information like this. I hope this post helped clear some things up. I'm not disagreeing that you should never use Teflon around your bird. TFE is very dangerous to inhale. I was just trying to show that you have to be careful about what you read on the internet because you never know when you will be given misinformation that may lead to the demise of your pet's health.
