Seafood safety

Monitoring for toxic environmental contaminants in commercially and recreationally important seafood species provides a measure of seafood quality and is necessary to evaluate the risk to human health. Research efforts by the Environmental Chemistry Program focus on developing rapid, sensitive methods to measure toxic chemicals, including emerging contaminants of concern, in a variety of seafood tissues. These methods are then used to ensure that seafood in U.S. waters is safe for human consumption, particularly in response to natural and man-made disasters that occur in important seafood rearing areas in the U.S. (see Disaster Response for more information).
