Polybrominated diphenyl ethers (PBDEs) are synthetic chemicals used for many years as flame retardants in plastic. Their molecules are not chemically bound to the polymers and gradually escape from products. They bio-accumulate in lipid tissue and biomagnified in the food chain. PBDEs are endocrine disruptors and have neurotoxic properties. The data about their contents in 500 samples of Polish food of animal origin were recently published. The 98.8% of samples were contaminated with at least one PBDE congener. In June 2023, the Contam Panel of EFSA concluded that it is likely that current dietary exposure to PBDEs in the European population raises a health concern.
