We have all heard of the potential health risk associated with teflon on our cooking pans, right? In case you haven't, read the highlights from a recent press release by the Sierra Club below about steps being taken to make it known by the state of California:

California is one step closer to adding Perfluorooctanoic acid (PFOA) to the Proposition 65 list of substances that can cause cancer. A legal challenge by a coalition of organizations cites the state’s failure to list PFOA, a chemical manufactured by DuPont and associated with Teflon and grease and stain repellants.

PFOA is a pervasive, synthetically-produced compound used in consumer and industrial products, including many non-stick surfaces found on cookware and stain-resistant, durable or all-weather clothing. It is prevalent in industries such as aerospace, automotive, building and construction, chemical processing, and electrical. PFOA’s use in popular consumer and industrial products has led to near universal exposure to the chemical.

Part of what makes PFOA such a pervasive and successful product is also responsible for its persistence. There is currently no known environmental breakdown mechanism for this chemical. As a result, PFOA accumulates in soil, water and air, as well as in humans and animals. Pervasive use and unyielding persistence have resulted in the bio-accumulation of PFOA in humans, presenting a serious risk in light of its impacts on human health. One study found that approximately 96% of children tested had PFOA in their blood. Numerous studies have confirmed daily exposure in people of all ages. The EPA Science Advisory Board has concluded in a draft risk assessment that PFOA is a likely human carcinogen. Studies also show liver, pancreatic and testicular cancer in animals, as well as statistically significant increases in tumors in test animals.
