Description

Per- and poly-fluoroalkyl substances (PFAS) are persistent contaminants in aquatic ecosystems, raising concern for hunting communities that rely on waterfowl for food, culture, and income. We analyzed PFAS in livers of blue-winged teal (dabblers) and canvasbacks (divers) harvested in Louisiana to assess how foraging strategy influences exposure. Divers had higher long-chain PFAS, while dabblers had higher short-chain compounds, consistent with expected differences in foraging strategies. PFOS was the dominant analyte in both species and occurred at concentrations that in many cases exceeded current European recommendations to avoid consumption. These results suggest potential dietary risk for hunters and families who regularly eat harvested ducks and underscore the need for communication and policy responses that address contaminants while supporting the cultural and economic importance of waterfowl hunting.
