"A $5 billion class-action lawsuit claiming DuPont Co. failed to disclose possible health risks from using the nonstick cookware is sought by owners of Teflon-coated pots and pans in 15 states.

The lawsuits claim DuPont concealed the results of its own studies, from Government and the consumers, that showed the material could become toxic when heated "enough to fry an egg," according to Des Moines attorney Kim Baer, who represents six plaintiffs from Iowa."

"The lawsuits allege that DuPont failed to disclose studies that showed that perflourooctanoic acid, also called PFOA or C-8, used in the Teflon manufacturing process releases toxic particulates when heated to 464 degrees, which can cause extreme damage to rats within 10 minutes and death at longer exposures.

Also at 680 degrees, Teflon-coated pans release six toxic gases including cancer-causing agents and PFOA, that can cause cancer in humans, as determined by the Science Advisory Board for the U.S. Environmental Protection Agency."
