When cleaning your George Foreman grill some of the black Teflon came off on top Is this safe to still use?

No, it is not safe to still use the George Foreman grill if the black Teflon coating has come off on top. Teflon (polytetrafluoroethylene) is a synthetic fluoropolymer that is widely used as a non-stick coating for cookware and other surfaces. When Teflon is heated to high temperatures, it can release harmful fumes that can cause flu-like symptoms, known as polymer fume fever. These fumes can irritate the eyes, nose, and throat, and can cause headaches, nausea, and vomiting. In severe cases, polymer fume fever can lead to difficulty breathing and damage to the lungs.

While the amount of Teflon that is released from a George Foreman grill is likely to be small, it is still best to avoid using the grill if the coating is damaged.

If the grill is still under warranty, you may be able to get it replaced. Otherwise, you should discard the grill and purchase a new one.
