中文摘要 | 2019年9月新北市發生校園腹瀉群聚事件,三校共 2,518 人食用同家食品公司供應的午餐後,200多人出現腸胃不適症狀。本調查針對其中兩校學生進行病例對照研究,利用問卷分析原因食品。562份有效問卷中,182人符合病例定義,症狀以腹痛和腹瀉為主,發病潛伏期中位數為15小時,依單變項及多變項分析結果推測原因食品為滷雞腿。因自發病個案糞便檢出產氣莢膜桿菌(Clostridium perfringens)且含有腸毒素基因cpe,加上個案臨床表現和潛伏期,推測病因物質為產氣莢膜桿菌。環境調查結果推測此事件可能與食品未澈底煮熟及保存時間過長有關。建議食品供應商落實重要管制點之監控,學校選擇團膳午餐供應商時可考量食品能否於烹煮後2至4小時食畢,以提高食品安全性。 |
英文摘要 | In September 2019, an outbreak of gastroenteritis occurred in three schools in New Taipei City. More than 200 students became ill after eating school lunch provided by the same caterer on September 3. Using a semi-structured questionnaire, food consumption in school lunch was assessed. Of 562 respondents with complete data, 182 met the case definition. Main symptoms included diarrhea and abdominal pain, with median incubation period of 15 hours. In univariate and multivariate analyses, consumption of braised chicken was associated with illness. Bacteria of cpe-positive C. perfringens were detected in 10 of 16 stool samples among 16 cases. Environmental investigation indicated inadequate cooking and storage procedures might have contributed to food contamination. We recommended that caterers should strengthen the implementation of the Hazard Analysis and Critical Control Points principles and schools should contract caterers complying with food safety standards (e.g. food can be served within two to four hours after cooking). |
