摘要

An outbreak of gastroenteritis occurred in a 95 Pingtung farmers tour group visiting Hwalien and Ban counties in northern Taiwan on July 22, 1986. Eighty-five (89%) of the 95 farmers were available for interview. Among them, 26 (31%) did not eat lunch boxes and none became ill. By Contrast, 27 (46%) of 59 persons who ate the lunch boxes became ill (P＜0.001). Clinical Symptoms of these Patients included vomiting (78%), abdominal pain (67%), and diarrhea (56%) with 3 hours median incubation period. Although the duration of illness was short (＜24 hours), symptoms were severe with hospitalization. Vomitus was collected from 22 persons and demonstrateded Staphylococcus aureus positive.
A comparison of illness rates among persons who ate and who did not eat specific food item showed a significant association with 5 out of 9 foods by univariate analysis. However, a multiple logistic analysis showed fish cakes were the only food item significantly associated with illness. Three leftover lunch boxes were available for laboratory examination. Fish cakes were located in the center of each lunch box and the other food items were placed either around or directly on top of the fish cakes. S. aureus (＞10^5 organisms Per gm) was isolated from all 9 food items in the lunch boxes. Staphy lococcus aureus with same antibiotic sensitivity pattern and enterotoxin ”A” was also isolated from the hands of fish cake maker, vomitus and left over food.
This Lesson illustrates that more efforts in health education is needed to prevent future food-borne outbreaks in Taiwan.
