S29 Controlling Bacterial Pathogens in Low-water Activity Foods and Spices

Monday, July 27, 2015: 8:30 AM-12:00 PM
C120 - C122 (Oregon Convention Center)

Low water activity (aw) and dried foods such as dried dairy and meat products, grain-based and dried ready-to-eat cereal products, powdered infant formula, peanut and nut pastes, as well as flours and meals have increasingly been associated with product recalls and foodborne outbreaks due to contamination by pathogens such as Salmonella spp. and enterohemorrhagic E. coli. In particular, recent foodborne outbreaks and product recalls related to Salmonella-contaminated spices have raised the level of public health concern for spices as agents of foodborne illnesses. Presently, most spices are grown outside the U.S., mainly in 8 countries: India, Indonesia, China, Brazil, Peru, Madagascar, Mexico and Vietnam. Many of these countries are underdeveloped and spices are harvested and stored with little heed to sanitation. The FDA has regulatory oversight of spices in the United States; however, the agency’s control is largely limited to enforcing regulatory compliance through sampling and testing only after imported foodstuffs have crossed the U.S. border. Unfortunately, statistical sampling plans are inefficient tools for ensuring total food safety. As a result, the development and use of decontamination treatments is key. This symposium will provide an understanding of the microbial challenges to the safety of low aw foods and provide a historic backdrop to the paradigm shift now highlighting low aw foods as vehicles for foodborne pathogens.  Up-to-date facts and figures of foodborne illness outbreaks and product recalls will be provided.  Special attention will be given to the uncanny ability of Salmonella to persist under dry conditions in food processing plants and foods. A lecture is specifically dedicated to processing plant investigations, providing practical approaches to determining sources of persistent bacterial strains in the industrial food processing environment. A lecture will also address the range of decontamination processes for spices
