# Is teflon a poison if ingested?

Nowadays, a lot of frying pans are made with a non-stick coating. That's usually teflon, or chemically speaking polytetrafluorethylene - $\ce{(C2F4)}_n$. Can you be poisoned if some of that teflon gets in your meal by scraping the pan or in any other way? And if so, what happens (chemically speaking) in your body after ingestion?

• Teflon is very inert and small pieces in the body will not be absorbed, so no. The only way to suffer from it is to overheat the pan enough to thermolyse the teflon back to the monomer, which is harmful (though less so to people than birds). – matt_black Apr 4 '18 at 18:22
