The U.S. Food and Drug Administration (FDA) is announcing that five perfluorinated substances used as grease-proofing agents have been voluntarily removed from interstate commerce by their manufacturers. After recent studies raised safety concerns with one type of perfluorinated chemicals, known as C8 compounds, FDA initiated a comprehensive review of the available data on C8 compounds. As a result of FDA’s initiative, manufacturers of these substances agreed to cease sale of all grease-proofing agents containing C8 perfluorinated compounds into the marketplace. This means that the affected products will no longer be sold for application on paper or paperboard intended for food contact use.
