"A link between eating certain imported fish and exposure to potentially toxic chemicals has been revealed by new research.

A team from the City University of Hong Kong (CityUHK), in collaboration with a group of international researchers, has published findings showing that commonly consumed fishes like salmon and cod are more likely to be contaminated with per- and polyfluoroalkyl substances, or PFAS—also known as forever chemicals—posing potential risks to our health.

Published in Science, the study analyzed edible marine fish that are widely traded and consumed around the world, including popular types like swordfish and tuna. Researchers found that imported fish brought into regions with relatively low environmental pollution contained significant levels of PFAS, raising concerns about food safety worldwide."
