Three grease-resistant chemicals linked to cancer and birth defects that are used in pizza boxes, microwave popcorn bags, sandwich wrappers, and other food packaging are being banned by the U.S. Food and Drug Administration.
The chemicals banned by the FDA, in an order that takes effect immediately, are three perfluorinated compounds or PFCs, a class that includes the chemicals used to make DuPont's Teflon and 3M's Scotchgard.
Through their use in thousands of consumer products, PFCs have polluted the blood of virtually all Americans, said the Environmental Working Group. They can be passed through the umbilical cord to the fetus. They contaminate drinking water for more than 6.5 million people in 27 states, according to water tests conducted by the U.S. Environmental Protection Agency.
