Abstract

ABSTRACT: An outbreak of gastrointestinal illness occurred at a hospital in northern Vermont during September 1981. Of the 292 hospital employees surveyed, 43 had diarrheal illness; 12 of them had positive cultures for Salmonella, serotypes chester, tennessee, or habana. In addition, three individuals who were culture-positive but did not have diarrhea were counted among the cases. Illness was related to eating roast beef or cold cuts (P<.01) in the month of September. One food specimen, an unopened package of precooked roast beef supplied by a New York processor, was found to be contaminated by Salmonella, serotypes chester, tennessee, and livingston. Cold cuts were believed to be secondarily contaminated by a meat slicer. Three of 80 patients whose charts were reviewed had nosocomial diarrhea; two of them had positive cultures for Salmonella, serotype and chester. Secondary transmission of Salmonella from hospital staff was the likely source for at least two of the patients.
