Shigella sonnei outbreak associated with contaminated drinking water - Island Park, Idaho, August 1995

Article Abstract:

An outbreak of shigellosis at a resort in Island Park, Idaho, may have been caused by contaminated well water. Shigellosis is a gastrointestinal infection caused by the bacterium Shigella. After receiving a report of shigellosis in a guest of the resort, The Idaho Department of Health questioned 221 people who had stayed at the resort in August, 1995. Eighty-two cases were identified. Those who became sick were more likely to have drunk tap water in their rooms or used the ice machine. No other foods and beverages were implicated, nor was swimming or using the hot tubs. Samples of water from the well that supplies the resort tested negative for Shigella as did well water from a nearby residential community. However, a sewer shared by both communities was found to be draining improperly and the water table was much higher than normal due to heavy rains. Six people in the residential community had also become ill from shigellosis.

An outbreak of Shigella dysenteriae type 2 among laboratory workers due to intentional food contamination

Article Abstract:

An outbreak of Shigella dysenteriae food poisoning in a Texas medical center was traced to intentional contamination of pastries with a strain of Shigella kept for research purposes. Twelve of 45 people working in a laboratory in the medical center became ill after eating muffins and doughnuts left in the break room. Analysis of stool samples revealed that the Shigella strain infecting 9 workers was identical to that found in the pastry and also to the strain kept by the laboratory. No other cases of Shigella were reported in the US during that time.

Salmonella serotype Montevideo infections associated with chicks - Idaho, Washington, and Oregon, spring 1995 and 1996

Article Abstract:

People who handle chicks and ducklings should wash their hands thoroughly after contact to avoid getting Salmonella poisoning. During the spring of 1995 and 1996, 23 people in Idaho and Washington and 16 in Oregon developed Salmonella poisoning with a strain known as Montevideo. Two-thirds to three-quarters of those infected had handled chicks in the week before their illness. Many were young children. In several cases studied in detail, the isolate from the chick matched the isolate from the patient.
