NTP Publishes Report on PFOA

The National Toxicology Program (NTP) published a report on perfluorooctanoic acid (PFOA).  The report, titled, Toxicology and Carcinogenesis Studies of Perfluorooctanoic Acid Administered in Feed to Sprague Dawley (Hsd:Sprague Dawley SD) Rats, May 2020, concludes that 2-year feeding studies provided clear evidence of carcinogenic activity of PFOA in male rats and some evidence of carcinogenicity of PFOA in female rats.

PFOA was recently classified by the International Agency for Research on Cancer (IARC) as being possibly carcinogenic to humans (Group 2B). In addition, PFOA, along with PFOS, are currently listed as developmental toxicants under California’s Proposition 65.
