Food-borne disease in hospitals: prevention in a changing food service environment.
The results of an investigation into an outbreak of food-borne disease at a hospital in Los Angeles County are reported. The outbreak occurred at a luncheon buffet for nonpatient visitors attending an event at the hospital, which was catered by the hospital. The food source and etiologic agent(s) responsible for the outbreak were not identified by our investigation. However, several issues relating to the changing character of hospital food provision and their implications for prevention of food-borne disease in hospitals were conspicuous. Two trends apparent in hospital food service are toward increased use of foodstuffs prepared by wholesale food manufacturers and more frequent invitation to community groups to meet within hospital facilities and use hospital catering services. We found that (1) hospital kitchens in Los Angeles County are undersurveyed with respect to frequency of sanitary inspections; (2) hospitals have no mechanism whereby to assess the sanitary inspection record of wholesale food manufacturers from whom they purchase foodstuffs; and (3) crossover of food items prepared for nonpatient hospital visitors, including catered foods, to the inpatient menu occurs. The potential risks for a food-borne disease outbreak among compromised inpatients resulting from these factors are discussed, and measures to reduce such risk are proposed.
