SaferWorldbyDesign Webinar: Fish Consumption Benefits and PFAS Risks Epidemiology

Tuesday, 25 June 2024 - 16:00 CET

Fish intake has been associated with benefits, although fish often has chemical contaminants that are associated with risks. Optimizing the benefits is desirable for individual and population health. However, comparison values (e.g., reference doses, RfDs) to estimate contaminant or pollutant safety thresholds typically do not account for the benefits of the foods that carry them (e.g., fish, eggs, fruit, vegetables). Rather, these numbers are applied the same way for various media such as food, soil, and water. This presentation summarizes principal epidemiology studies on per- and polyfluoroalkyl substances (PFAS)-associated noncancer health indicators used by the United States Environmental Protection Agency to develop RfDs for PFAS and compares these with the same health outcomes associated with fish intake. In addition, it discusses approaches that risk assessors and policy makers might consider in developing their fish consumption recommendations in relation to PFAS.
