摘　　要：目的分析山东省德州市某学校一起食源性疾病暴发疫情的致病因子及其污染来源,为预防类似事件发生提供依据。方法通过流行病学调查和食品卫生学调查,查找可疑餐次;运用病例对照研究分析发病的危险因素;采集病例、食品和环境的样品,开展细菌性及病毒性病原体实验室检测。结果共搜索到80例病例,其中确诊病例3例,罹患率2.65%。临床表现以腹痛、恶心为主。可疑餐次为9月14日早餐;清炒海带丝为该起疫情的危险因素(OR=10.370,95%CI:3.090~34.800)。3份病例粪便标本中均检出副溶血性弧菌,毒力基因相同,分子分型检测结果高度同源;1份供货商环境样本检出副溶血弧菌。结论本次疫情是由副溶血弧菌感染引发的食源性疾病暴发疫情;建议加强餐饮食品环节安全监管,切实把好食品进购索证关,加强学校的健康教育宣传工作,提高卫生安全意识。Objective To find out the pathogenic factors and the contamination source of a foodborne disease outbreak in a school in Dezhou city of Shandong province,and provide basis for preventing the occurrence of similar event.Methods The epidemiological survey and food hygiene survey were carried out to find out the suspected meals,and the risk factors of the disease were be analyzed with case-control study method.The samples were collected from patients,food and environment for pathogen of bacteria and virus testing in laboratory.Results Of 80 cases searched,3 cases were confirmed,and the attack rate was 2.65%.Abdominal pain and nausea were the main clinical manifestations.The suspected meal was the breakfast on September 14th.Stir-fried kelp strips was the risk factor in the outbreak(OR=10.370,95%CI:3.090-34.800).The vibrio parahaemolyticus were detected in all three fecal samples from the cases,with same identical virulence genes.The results of molecular typing were highly homologous.The vibrio parahaemolyticus was also detected in one environmental sample from the supplier.Conclusions This is a foodborne disease outbreak caused by vibrio parahaemolyticus infection.It is suggested to strengthen the supervision and management for food safety in the catering industry.The requirement for certificate during food purchase should be done well.The health publicity and education in schools should be strengthened to raise the awareness of hygiene and safety.
