Eating fish tainted with PCBs may cause memory loss and brain damage in adults, according to a study of Michigan residents. The study by the University of Illinois at Urbana-Champaign is one of the first to suggest that PCBs in fish may have health implications for all adults; state fish advisories until now have focused on protecting pregnant women, fetuses, and young children. Michigan ships Lake Michigan whitefish and lake trout to restaurants all over the country without health warnings for PCBs, mercury, or other pollutants.
