目的了解成都市食品和公共场所从业人员肠道沙门菌带菌状况,为加强卫生管理、防控肠道传染病提供科学依据。方法对2016-01/09成都市疾病预防控制中心15 613名食品和公共场所从业人员预防性健康检查肛拭样品中沙门菌的检出结果进行回顾性分析。结果检出沙门菌6株,共5个血清型,总检出率0.38‰;食品从业人员检出率0.35‰,公共场所从业人员检出率0.49‰,二者差异无统计学意义(P>0.05);男性检出率0.29‰,女性检出率0.45‰,二者差异无统计学意义(P>0.05)。结论成都市食品和公共场所从业人员肠道沙门菌阳性携带率较低,但应考虑到从业人员体检前预防性用药及沙门菌传统检验方法检出率相对较低的因素;为防止食物中毒和肠道传染病的发生,应加强对食品、公共场所从业人员的肠道致病菌携带状况检查和卫生知识培训。
Objective To understand the status of intestinal bacteria of enteric Salmonella in food and public places in Chengdu and provide a scientific basis for strengthening health management and preventing and controlling intestinal infectious diseases.

Results Six strains of Salmonella were detected, with a total of five serotypes, with a total detection rate of 0.38 ‰; the detection rate of food practitioners was 0.35 ‰ and the detection rate of public practitioners was 0.49 ‰, with no significant difference between the two groups (P> 0.05). The detection rate was 0.29 ‰ in males and 0.45 ‰ in females. There was no significant difference between them (P> 0.05). Conclusion The prevalence of enteric Salmonella positive rate in food and public places in Chengdu is relatively low. However, taking into account the preventive measures taken by practitioners prior to physical examination and the relatively low detection rate of Salmonella traditional detection methods, in order to prevent food poisoning and The occurrence of intestinal infectious diseases should be strengthened on food, public places practitioners of intestinal bacteria carrying status checks and health knowledge training.
