PFAS Levels in Lancashire Eggs
Health officials in Lancashire have issued a stark warning to residents near the Hillhouse Technology Enterprise Zone, advising against the consumption of locally produced eggs and poultry. The advisory follows the discovery of elevated concentrations of Perfluorooctanoic Acid (PFOA), a potent member of the "forever chemicals" family, within a 1km radius of a former ICI manufacturing site in Thornton-Cleveleys. The source of the contamination is linked to historical industrial activity at the site, which is currently operated by AGC Chemicals Europe Ltd but was formerly managed by Imperial Chemical Industries (ICI). The substance was used extensively in manufacturing processes between the 1950s and 2012.
Known as "forever chemicals" due to their incredibly strong carbon-fluorine bonds, PFAS do not degrade naturally in the environment. This leads to bioaccumulation, where the chemicals move from the soil and water into the tissues of plants and animals, eventually reaching human consumers.
The bioaccumulation factor in avian species is particularly concerning, as PFAS tend to bind to proteins in the yolk, making eggs a highly efficient delivery mechanism for these toxins into the human diet.
