The claims come almost a year to the day after the EPA issued a May 2023 press release that stated the agency found no per- and polyfluoroalkyl substances (PFAS) in testing of samples of certain insecticide products. The press release contradicted a published study by the former EPA researcher that had reported finding PFAS in the same pesticide products.
