Consumption of fish: Benefits and perceived risk

Fish, a useful source of protein, may be polluted by microbes, natural toxins, and/or synthetic chemicals. However, based on a review of the U.S. General Accounting Office, “There does not appear to be a compelling case to implement a mandatory comprehensive federal seafood inspection program.” Although earlier studies showed higher body burdens of polychlorinated biphenyls (PCBs) in populations who consumed a lot of fish from polluted waterways, a recent study refutes these observations. No information is available in the United States on the levels of polychlorinated dibenzodioxins (PCDDs) and dibenzofurans (PCDFs) in anglers who consume a great deal of fish presumed to be contaminated by these chemicals.
