LONG recommended for their nutritional benefits, some shellfish may contain higher levels of PFAS ‘forever chemicals’ than fish, reports an American study.

With magnesium, copper, iodine and selenium, shellfish are packed with minerals, and are a good source of vitamins B3 and B5. However, research led by scientists at Dartmouth College in the United States suggests that people who frequently consume shellfish may face an increased risk of exposure to harmful levels of PFAS, or toxins known as ‘forever chemicals.’
