Stacey (Etheridge) DeGrasseStacey (Etheridge) DeGrasse, Ph. D. 

Research Biologist
Seafood Research Area Coordinator
Office of Regulatory Science 
Center for Food Safety and Applied Nutrition (CFSAN)
U.S. FDA’s


Stacey DeGrasse received her Bachelor of Science in Biology from the University of Alabama, and her Master of Science and her Doctorate in Oceanography from the University of Connecticut. Prior to her current position, Stacey spent a year as a post-doctoral staff fellow at CFSAN where she conducted research on marine biotoxin detection methods. Her research interests are related to food safety and food defense and include developing detection methods for foodborne toxins, investigating traditional and emerging sources and vectors of foodborne toxins, and studying the dynamics of toxic algae and the transfer of toxins to seafood. Among her many research projects, she currently oversees FDA’s contribution in a large, multi-laboratory interdisciplinary investigation on toxic algal blooms and shellfish toxicity (associated with paralytic shellfish poisoning) off the coast of New England, the goal of which is to improve management of this seafood safety hazard. She is also currently involved in a diverse range of projects focusing on method development for detection of seafood toxins. Stacey has served as FDA’s representative on the Interagency Working Group on Harmful Algal Blooms, Hypoxia and Human Health (IWG-4H). Currently, she is a member of the AOAC’s Presidential Task Force on Marine and Freshwater Toxins, and is FDA’s delegate on the ISSC (Interstate Shellfish Sanitation Conference) Biotoxin Committee.
