PFAS in our food: From farms and fields to streams and shores

The concern of per- and polyfluoroalkyl substances (PFAS) contamination has historically focused on drinking water, but communities and researchers are increasingly realizing that drinking water may not be the only important exposure pathway. PFAS move through surface water, sediments and soils into groundwater, wildlife and even our agricultural systems. Consequently, they affect the foods that shape daily life, cultural traditions and community health. Research on dietary PFAS exposure has typically been confined to fish consumption despite the potential for broader impacts given the widespread occurrence of PFAS in the environment.
