California continues to increase the scope of Prop 65’s PFAS-related listings. As we previously reported, in December 2021 California formally listed PFOS as a carcinogen and PFNA and as a reproductive toxin under Prop 65.
On February 25, California added PFOA to its Prop 65 list for cancer. PFOA was already listed for reproductive harm. The formal notice states: “The listing of perfluorooctanoic acid (PFOA) is based on its formal identification by the National Toxicology Program (NTP), an authoritative body for purposes of Proposition 65, that the chemical causes cancer.”
