Investigation of multidrug-resistant Salmonella serotype Typhimurium DT104 infections linked to raw-milk cheese in Washington State.
Context Multidrug-resistant Salmonella Typhimurium DT104 has recently emerged as a cause of human and animal illness in Europe and North America.
In early 1997, health officials in Yakima County, Washington, noted a 5-fold increase in salmonellosis among the county's Hispanic population.
Objectives To characterize bacterial strains and identify risk factors for infection with Salmonella Typhimurium in Yakima County.
Design Laboratory, case-control, and environmental investigations.
Setting and Participants Patients with culture-confirmed Salmonella Typhimurium infection living in Yakima County and age-and neighborhood-matched control subjects.
Main Outcome Measures Food vehicle implication based on case-control study and outbreak control.
Results Between January 1 and May 5,1997,54 culture-confirmed cases of Salmonella Typhimurium were reported.
The median age of patients was 4 years and 91% were Hispanic.
Patients reported diarrhea (100%), abdominal cramps (93%), fever (93%), bloody stools (72%), and vomiting (53%) ; 5 patients (9%) were hospitalized.
Twenty-two patients and 61 control subjects were enrolled in the case-control study.
Seventeen case patients (77%) reported eating unpasteurized Mexican-style soft cheese in the 7 days before onset of illness compared with 17 control subjects (28%) (matched odds ratio, 32.3 ; 95% confidence interval, 3.0-874.6). (...)
