"Forever Chemicals" in Greek Free-Range Eggs: Health Risks

A scientific study by the National and Kapodistrian University of Athens (EKPA) and the University of the Aegean has revealed high concentrations of per- and polyfluoroalkyl substances (PFAS), also known as "forever chemicals," in free-range eggs in Greece. The study, published in Science of The Total Environment, warns of potential health risks.

The research examined 75 eggs from farms in five regions: Serres, Magnesia, Boeotia, Attica, and Ilia. The results showed residues of drugs and pesticides, including the insect repellent DEET, in concentrations exceeding the permissible limits of the European Union in more than half of the samples. The largest exceedances were observed in Ilia.

Nikos Thomaidis, Professor of Analytical Chemistry at EKPA, stated that the findings indicate the need for intensified controls, as there is a potential risk for high egg consumers (more than two per day). Scientists explain that free-range hens may consume contaminated soil, water, or feed, leading to the accumulation of these substances in the eggs.
