Providers at a university student health center in Baltimore noticed an increased number of patients with acute gastroenteritis and fever over a six-day period in December 2014. Investigators from the Baltimore City Health Department were notified, and an epidemiologic investigation was undertaken to determine the cause of the outbreak. Blood and stool samples were collected. Laboratory data indicated that the organism causing the gastroenteritis was Salmonella. Two hundred students (80 sick and 120 not sick) were interviewed, and many reported having eaten at The Rusty LunchBucket, a soup-salad-and-sandwich deli on campus. Each person was asked whether they had eaten soup, salad, or sandwich, or any combination of the three. Data from the investigation are provided below.
