Dr. Dickson has developed a predictive model to estimate the growth of salmonellae during the cooling of beef carcasses. This model was used during an evaluation of proposed USDA regulations, to determine the relative probability of salmonellae growth under a variety of cooling conditions. Dr. Dickson's studies of bacterial attachment, carcass washing and sanitizing have been applied to animal processing environments, resulting in the development of an inexpensive, technology neutral process which is very effective in controlling enteric pathogens on animal carcasses. Dr. Dickson has been involved in a variety of training courses, including hosting four International Atomic Energy Agency training fellowships in his laboratory, and teaching the principles of meat microbiology and HACCP to food industry audiences in Japan. He also traveled to the People's Republic of China and Singapore, evaluating meat processing systems. Dr. Dickson served on the National Academy of Science's panel on review of the use of scientific criteria and performance standards for safe food, where he served as chair of the Meat and Poultry sub-committee.
