摘　　要：目的分析一起食物中毒事件的可疑食品、致病因子及污染来源,探讨其预防控制措施。方法采用现场流行病学、食品卫生学调查、病例对照分析方法,结合实验室检测结果对危险因素进行分析。结果共搜集80例病例,罹患率为32.30%。病例以发热(96.25%)、腹泻(77.50%)、腹痛(68.75%)为主要症状,部分伴有呕吐(25.00%),病例对照结果显示吃蒜蓉蒸扇贝(OR=7.358,95%CI:2.082~26.005)和叉烧鱿鱼(OR=5.478,95%CI:1.868~16.061)与发病具有较强的统计学关联。实验室PCR检测结果显示,蒜蓉蒸扇贝和叉烧鱿鱼沙门菌阳性,44份肛拭子标本沙门菌阳性。5例病例便培养结果均为肠炎沙门菌,5株菌株的脉冲场凝胶电泳图谱完全一致。结论结合现场流行病学调查结果、临床表现和实验室检测,判定这是一起由扇贝被沙门菌污染导致的食物中毒事件,提示应加强餐饮企业的源头管理,食物食用前应彻底加热,避免长时间存放,从而保障群众的饮食安全。Objective To analyze the suspicious food, causative agent and source of contamination in a food poisoning incident and explore its preventive and control measures.Methods Analysis of risk factors using on-site epidemiology, food hygiene investigation, case-control analysis methods, combined with laboratory test results.Results A total of 80 cases were collected, the incidence rate was 32.30%.Fever(96.25%),diarrhoea(77.50%)and abdominal pain(68.75%)were the main symptoms, some of which were accompanied by vomiting(25.00%).The case-control results showed that eating Steamed scallop with garlic(OR=7.358,95%CI:2.082-26.005) and barbecued squid(OR=5.478,95%CI:1.868-16.061) had a strong statistical association with tmorbidity.Laboratory PCR test results showed that Salmonella was positive in garlic steamed scallop and barbecued squid, and Salmonella was positive in 44 anal swab sepcimens.The stool culture results of all five cases were positive for Salmonella enteritidis,and the pulsed field gel electrophoresis profiles of the five strains were completely consistent.Conclusion Combining the results of the on-site epidemiological investigation, clinical manifestations and laboratory tests, it is determined that tis is a food poisoning incident caused by scallops contaminated with Salmonella,suggesting that the source management of catering enterprises should be strengthened, food should be thoroughly heated before consumption and avoided long-term storage, so as to safeguard the food safety of the public.
