Do all non-stick pans contain teflon?
No. Teflon is a very specific product produced by DuPont. If a pan has a Teflon coating, it will have a blue Teflon label clearly showing on the packaging. Most nonstick pans use a nonstick coating that is similar to Teflon, but is not Teflon. Some are more durable, like the ones used by Calphalon, Analon, and AllClad. With proper use and care (no high heat cooking, no Pam, no metal utensils) they will last 20 years. Teflon has been shown to cause incidents of cancer in the factory workers (in the 70’s) who were applying the coating to the pans. But there has never been a documented case of Teflon causing serious health risks in a home kitchen.
