Concerns about the health risks of Teflon were heightened when the chemical used to produce it caused liver cancer in lab rats. But now, an independent study of people living near a plant that uses the chemical found no relationship to liver, kidney, or thyroid cancer.

Emmett says further testing could and should be done, but for now, this is one concern about Teflon that doesn’t appear likely to stick.
