Per- and polyfluorinated alkyl substances (PFAS), which include PFOS (perfluorooctanesulfonic acid) and PFOA (perfluorooctanoic acid), are persistent organic pollutants (POPs) that can accumulate in water, soil, animals, and the human body. Due to their health and environmental impact, these contaminants have been a focus of the European Food Safety Authority (EFSA) for several years. Eurofins Food & Feed Testing offers accredited analysis for a broad range of PFAS substances.
