Public health officials have issued new guidelines for eating fish caught in Illinois rivers and lakes. The Illinois Fish Contaminant Monitoring Program tests fish from the state's bodies of water each year. Carp from Sycamore Lake in DeKalb County should only be eaten once a week.
From IDPH:The meal advisories for fish found with elevated levels of chlordane, dioxin, methylmercury and polychlorinated biphenyls (PCBs) are based primarily on protecting sensitive populations, most particularly women who are pregnant, nursing, or of childbearing age, fetuses, and children younger than 15 years of age. All advisories may be overprotective for women beyond childbearing age and males 15 years of age and older.
