An outbreak of Salmonella Typhimurium, PT 108, spread from a food court on the campus of The University of Western Ontario. There were two phases of the outbreak. The first phase appeared to be related to food from the University Community Center (UCC). Initially the majority of ill persons had eaten at the pita outlet. The second phase was related to eating food prepared at the UCC, but available at a variety of on-campus locations. Food handlers were infected with Salmonella, however the onset of their illnesses occurred after the beginning of the outbreak so they were not likely to be the original source of the outbreak. Food service inspection revealed some problems with food handling and cross contamination potential. Raw chicken was routinely handled near the pita station. Salmonella Heidelberg was isolated from the raw chicken. Bacillus cereus was isolated from a chicken sample taken directly from the pita outlet.
