Dr Nicholas Ralston

Dr Nicholas RalstonIn 2002, Nick Ralston took a position at the University of North Dakota working with the Environmental Protection Agency-funded Center for Air Toxic Metals Health Effects program. Last week, Ralston and his colleagues published the results of their seven-year-long study, which shows that current U.S. Food and Drug Administration methods for developing seafood consumption guidelines may not provide an accurate assessment of seafood safety. The study’s results led them to develop the Selenium Health Benefit Value criterion, which predicts risks or benefits of seafood species based on methylmercury and selenium content. Ralston recently talked to SeafoodSource about the study’s implications and what it could mean for the future of FDA’s seafood-consumption recommendations.
