Concerns Remain on Voluntary C-8 Phase Out

Oakland, Calif. - The chemical industry’s agreement with the federal Food and Drug Administration to phase out toxic perfluorinated compounds used to grease-proof pizza boxes, microwave popcorn bags, fast food wrapping and other food packaging does not go far enough to protect public health.

“Prior to this voluntary phase-out, these manufacturers have polluted the planet with these persistent and carcinogenic compounds,” Renee Sharp, Environmental Working Group senior scientist, said. “While we’re glad that some progress is being made to take these harmful chemicals off the market, the chemical industry hardly deserves a pat on the back.”

The FDA announced yesterday that five of these compounds, known as “C-8” compounds, “will no longer be sold for application on paper or paperboard intended for food contact use.”

The five chemicals are all very similar to PFOA, one of the most notorious chemicals ever made. Perfluorooctanoic acid, or PFOA, is found in the blood of more than 98 percent of Americans, builds up in the food chain, contaminates wildlife around the globe, and is linked to a wide array of health effects. In April of this year, an independent scientific panel approved by the DuPont company as part of a class action lawsuit linked PFOA to kidney and testicular cancer in humans.

In 2005, the Environmental Protection Agency fined DuPont $10 million – the largest civil penalty ever levied under any environmental statute at the time – for hiding information that PFOA was a serious public health risk.

Chemical manufacturers have been moving at a snail’s pace to protect the public from the dangers posed by these compounds. Unfortunately, while manufacturers came up with substitutes after the FDA and the industry agreed to phase out C-8 compounds, public records show that some of these alternatives may be just as bad or worse.

PFOA is sometimes called C-8 because it has 8 carbon atoms. A key replacement chemical, perfluorohexanoic acid (PFHxA), contains 6 carbon atoms and is often called C6. The chemical industry would have us believe that the removal of two carbon atoms removes human health risks. Yet these C-6 compounds are extraordinarily persistent in the environment, cross the placenta to contaminate children before birth and are potentially 3 to 5 times more toxic than C-8 to aquatic organisms.

A 2008 EWG review of FDA safety assessments for 8 new fluorochemical-based food packaging chemicals found no evidence that FDA adequately assessed the safety of people's exposures to C-6 from these coatings, and found the toxicity data for the C-8 replacements to be sparse.

“Health agencies should be looking beyond food packaging to see the full use of these disturbing compounds,” Sharp said. “Until manufacturers conduct transparent, thorough safety analyses of these materials, we cannot trust their green-washed replacements.”


We know things are bad. We know it's worth the fight.

You are part of a strong and vibrant community of thinkers and doers who believe another world is possible. Alone we are weak. Together we can make a difference. At Common Dreams, we don't look away from the world—we are not afraid—our mission is to document those doing wrong and galvanize those doing good. But we can't do it alone. It doesn't work that way. We need you. We have now launched our annual Summer Campaign. Can you pitch in today?

The mission of the Environmental Working Group (EWG) is to use the power of public information to protect public health and the environment. EWG is a 501(c)(3) non-profit organization, founded in 1993 by Ken Cook and Richard Wiles.
