Is the coating of non-stick pan (Teflon) toxic?

Teflon coating is nontoxic under normal conditions. Teflon coating is mainly made of fluoropolymer, and its composition is polytetrafluoroethylene. The decomposition temperature of PTFE is 350℃. Even cooking with oil, our daily cooking temperature is between 200℃ and 250℃, and no toxic substances will be released. Is Teflon Coating Toxic? When using non-stick pan, we should pay attention to avoid "dry pan". Dry burning will cause the coating to decompose at too high a temperature, and inhalation of smoke generated by the burning of non-stick cooking coating may lead to headache, fever and other symptoms. If the non-stick coating is eaten in the stomach, it will not affect human health, and the coating will be completely excreted. When the coating of the non-stick pan begins to fall off, we suggest not to use this pan again. One is that cooking will stick to the pot, and the other is to avoid eating more coatings.
