Is teflon poinsonous??
At room temperature, Teflon is absolutely inert to every conceivable reagent; bottles made of Teflon can be used to hold superacids, for example, as well as very strong oxidizing agents. It is ideal for implants for this reason. Teflon will pass straight through the body unaffected. At higher temperatures, a bit above the range of temperatures used to cook meat, Teflon starts to decompose. The vapours released as this occurs can be lethal to birds, and cause flu-like symptoms in humans, however a 1959 study reported that the toxicity of these fumes is less than that of those released by ordinary cooking oils at these temperatures [Wikipedia].
