Personal Information

Dr. George J. Flick, Jr. received his B.A. degree in Chemistry from Louisiana State University in 1963. He was awarded the M.S. and Ph.D. degrees in Food Science and Technology from Louisiana State University in 1965 and 1969 respectively. He served in the U.S. armed forces (159th Fighter Interceptor Squadron) from 1963 to 1969 and was awarded an Honorable Discharge. Dr. Flick has been a visiting professor in the Department of Marine Biochemistry, University of Tokyo, Tokyo, Japan and the Chemistry Department, National University of Mexico, Mexico City, Mexico. Dr. Flick joined the Food Science and Technology Department at Virginia Tech in 1969 as an Assistant Professor. In 1996, he was promoted to University Distinguished Professor. He is a Fellow of the Institute of Food Technologists and the American Association for the Advancement of Science.

Current Projects

George Flick's research projects are primarily concerned with the utilization of wild and aquacultured fish and shellfish for food, feed, and industrial products. The main beneficiaries of the program are seafood producers (including aquaculture enterprises), processors, retailers, and the food service industry. Most federal funding for his projects are provided by the U.S. Department of Agriculture and U.S. Department of Commerce. He has been active with several industry associations and professional organizations, including the National Fisheries Institute (NFI), Institute of Food Technologists (IFT), Central Atlantic States Association of Food and Drug Officials (CASA), American Chemical Society (ACS), International Association for Food Protection (IAFP), and World Aquaculture Society (WAS).

Currently, one doctoral candidate and three laboratory assistants are working on the following topics: the effects of harvesting, processing and distribution on the formation of histamine and other biogenic amines in major commercial mid-Atlantic fish species; the presence and dynamics of Listeria monocytogenes and other Listeria species in ready-to-eat fish and shellfish products (i.e., smoked fish, crab meat, shrimp); and the effects of high pressure processing on the quality and safety of oysters (Crassostrea virginica and C. ariakensis); effects of varying high processing pressures on the inactivation of the spore forming microorganism Bacillus cereus; identification of microorganisms surviving high pressure treatments in various fresh and processed foods.
