【摘要】 目的 分析浙江省肉鸡来源预制菜中沙门菌的污染情况，评估浙江省肉鸡来源的预制菜中沙门菌对人群的致病风险。方法 对2020—2023年收集的浙江省零售鸡肉来源的预制菜中的沙门菌进行定量检测，根据2024年浙江省城市居民预制食品消费行为调查结果，应用快速微生物定量风险评估软件（sQMRA）开展肉鸡来源的预制菜中沙门菌风险评估。结果 2020—2023年浙江省零售鸡肉来源的预制菜中的沙门菌检出率为13.3%（44/330）。浙江省居民通过肉鸡来源预制菜发生沙门菌中毒的年度预期发病人数为1 594人，患病概率为3.11×10^-5，稍低于监测系统报告的病例数结果。结论 需高度重视沙门菌致病风险，针对肉鸡来源的预制菜运输、零售、养殖、加工环节强化交叉污染防控措施；同时加大零售环节该类产品的监督管理力度，构建并完善食源性疾病监测预警网络，为精准降低沙门菌相关食源性疾病风险提供保障。更多还原

【Abstract】 Objective To analyze the contamination of Salmonella in prepared dishes from broilers in Zhejiang, China, and to evaluate the risk of Salmonella infection in the population.Methods From 2020 to 2023, quantitative detection of Salmonella in prepared chicken dishes from retail sources in Zhejiang was conducted. Based on the results of the 2024 survey on the consumption behavior of prepared dishes among urban residents, the Salmonella risk assessment of prepared chicken dishes was carried out using the rapid quantitative microbiological risk assessment（sQMRA）.Results The detection rate of Salmonella in prepared chicken dishes from retail sources in Zhejiang 2020—2023 was 13. 3%（44/330）. The annual expected number of cases of Salmonella infection among Zhejiang residents due to prepared chicken dishes was 1 594, with a probability of illness at 3. 11×10^-5, which was slightly lower than the number of cases reported by the monitoring system.Conclusion Great attention need to be paid to health risk posed by Salmonella. Cross-contamination control should be strengthened in transportation, retail, breeding, and processing stage of prepared dishes made from broiler chickens. Simultaneously, supervision and management of such products in the retail sector should be enhanced, and a monitoring and early warning network for foodborne diseases should be established, and therefore, systematically reduced the risk of foodborne diseases related to Salmonella.更多还原
