Summary Introduction
Introduction:
Salmonella is the etiological agent responsible for the outbreak of diarrheal illness.
Case summary:
On April 2, 2130 students and employees of a public school developed diarrheal illness. The cafeteria served chicken on that day. Part of the chicken was placed in water-filled pans and cooked in an oven for 2 hours at a dial setting of 177º C on April 1. After turning off the oven, the chicken was left overnight in the warm oven. The remainder of the chicken was cooked for 2 hours in a steam cooker and then left in the device overnight at the lowest possible setting (43º C). From 32 patients, two serotypes of a gram-negative, cytochrome oxidase-negative, lactose-negative rods were isolated.
