Keith R. Schneider, Ph.D.
Education
1991 Ph.D. Food Science & Human Nutrition, University of Florida
1987 M.S. Public Health, University of South Florida
1984 B.S. Education, University of Florida
Research Interests
Research interests include a focus in the area of food safety, particularly with respect to produce, juice and beverage safety. A major effort has been expended in the area of risk assessment and mitigation of foodborne pathogens associated with fresh produce. Processing technologies, including chemical and microbiological characterization of processing parameters, and alternative technologies for the reduction and/or elimination of microbial contamination also comprise a portion of the research assignment. These programs are extramurally funded. This also involves development of an active graduate student-training program, primarily within the Food Science and Human Nutrition Department, and service to the University and the food industry as needed.
Teaching
Teaching responsibilities have focused on graduate student advising and in the development of distance education courses. The main area of student activity has concentrated on the microbial safety of all foods, with a specific emphasis on produce. This is a stated departmental priority for both research and teaching programs. The distance educations courses created to date include Food Safety and Sanitation and HACCP Systems. The on-campus Current Issues in Food Science and Nutrition was created to introduce students to a wide range of topics currently in the news.
