Overview
- An Environmental Working Group analysis of California pesticide-use records estimates about 15 million pounds of PFAS applied to cropland from 2018 to 2023, or roughly 2.5 million pounds per year.
- The review identified 51 PFAS used across 58 counties, with Fresno, Kern, San Joaquin, Napa and Riverside showing the highest concentrations.
- PFAS are present in pesticides used on crops including almonds, pistachios, wine grapes, alfalfa and tomatoes.
- Researchers warn that short-chain PFAS move easily through the environment and can break down into trifluoroacetic acid, with studies indicating higher uptake risks in water-rich produce.
- The findings renew calls for testing of food, water and worker exposures as the European Union bans several PFAS used in pesticides, while U.S. policies remain contested and farm groups dispute EWG’s definitions.
