Objectives: We investigated a salmonellosis outbreak related to a cafeteria to determine its extent and to identify illness risk factors.
Methods: A case was defined as isolation of Salmonella Group D or serotype Enteritidis from the stool of a person who ate at the cafeteria during June 22-July 10, 2003, and developed diarrhea in 3 days or less. Food histories of case patients (n = 11) were compared with those of their well meal companions (n = 16).
Results: Consumption of coconut meringue pie was associated with illness (odds ratio = 150.0; 95% confidence interval = 6.4-6901.4). Meringue was made with raw shell eggs and was baked to an internal temperature of 83°F.
Conclusions: Restaurant operators and public health officials should be alert for recipes containing raw shell eggs. Food service operators should use pasteurized egg products in meringue recipes if meringue will not be cooked to the required temperature of 155°F. For clarification purposes, policy makers should consider adding meringue to the Food Safety Rule that lists foods in which pasteurized eggs should be substituted for raw shell eggs.
