Nontyphoidal infection is a common cause of bacterial foodborne illness in Zhejiang Province, China. This study aimed to summarize the epidemiological and etiological characteristics of the outbreak of nontyphoidal infection in Zhejiang Province. Data collected over a 10-year period (2010-2019) from the China National Foodborne Diseases Surveillance Network (NFDSN) were analyzed. A total of 78 outbreaks due to nontyphoidal , causing 1450 illnesses and 353 hospitalizations with no deaths, were reported. The outbreak rate from May to October was about four times as high as that in other months. In addition, 33.3% (25/78) outbreaks occurred in household settings, and 41.8% (606/1450) cases were exposed at bakery product-processing factories (or shops). Moreover, food vehicles were identified in 75.6% (59/78) of outbreaks. Of these, 30.5% (35/59) were caused by cooked meat products, followed by cold-processed cakes and sandwiches usually containing meat and/or eggs (28.81%, 17/59). Enteritidis (56.9%, 33/78) and Typhimurium (17.2%, 10/78) were the dominant strains. Outbreaks were most frequently attributed to cross-contamination (88.1%) and improper storage temperature (61.0%). Outbreaks caused by are important targets for public health intervention efforts, and improving the safety and quality of cooked meat products, cold-processed cakes, and sandwiches should be a priority.
非伤寒型感染是中国浙江省细菌性食源性疾病的常见病因。本研究旨在总结浙江省非伤寒型感染暴发的流行病学和病原学特征。对中国食源性疾病监测网络（NFDSN）在过去 10 年（2010-2019 年）收集的数据进行了分析。共报告了 78 起因非伤寒型引起的暴发，导致 1450 例疾病和 353 例住院，无死亡。5 月至 10 月的暴发率约为其他月份的四倍。此外，33.3%（25/78）的暴发发生在家庭环境中，41.8%（606/1450）的病例暴露于糕点加工工厂（或商店）。此外，在 75.6%（59/78）的暴发中确定了食品车辆。其中，30.5%（35/59）由熟肉制品引起，其次是通常含有肉和/或鸡蛋的冷加工蛋糕和三明治（28.81%，17/59）。肠炎沙门氏菌（56.9%，33/78）和鼠伤寒沙门氏菌（17.2%，10/78）是主要菌株。暴发最常归因于交叉污染（88.1%）和不当储存温度（61.0%）。由 引起的暴发是公共卫生干预措施的重要目标，应优先考虑提高熟肉制品、冷加工蛋糕和三明治的安全性和质量。
