that University of North Carolina tests in 21 states found average mercury levels in tuna and swordfish at 1.1 parts per million, over the government's limit of 1 ppm. The samples came from supermarket chains, including Safeway and Whole Foods, and some groups are pushing for supermarkets to include warning signs with their seafood displays.
Mercury can cause neurological and developmental problems in children, and women of child-bearing age, infants and children are advised to avoid fish high in mercury, including white albacore tuna, swordfish, tilefish and shark.
EWG's work on mercury and seafood is here.
