摘要

沙门氏菌是一种食源性致病菌,对公众健康构成严重威胁。该文综述了沙门氏菌的内化机制研究、食品污染源的追踪方法及防控策略。首先,探讨了沙门氏菌通过气孔、根部组织和损伤部位等途径内化进入果蔬的机制,以及鞭毛、菌毛等细菌学相关因素、植物和环境因素对内化过程的影响。同时,分析了内化过程及内化后存活规律与机制。在食品污染源追踪方面,介绍了微生物学检测方法和分子生物学溯源技术等追踪手段,并分析了污染源追踪的过程、验证与应用。最后,该文提出了一系列防控策略,包括加强食品生产、加工、贮存和运输环节的卫生管理,提高公众的食品安全意识和卫生习惯,及时发现与处理污染食品,有效隔离与消毒污染源,建立完善的食品安全应急响应机制,以及加强政府部门、企业与公众之间的沟通与协作,以期降低沙门氏菌对公众健康的危害。

Abstract

Salmonella is a foodborne pathogen that poses a serious threat to public health.This paper reviewed the studies on the internalization mechanism of Salmonella, the methods of tracing the source of food contamination, and the prevention and control strategies.Firstly, the mechanism of Salmonella internalization into fruits and vegetables through stomata, root tissues and injury sites were explored, as well as the influence of bacteriologically relevant factors such as flagella and pili, and plant and environmental factors on the internalization process.Meanwhile, the internalization process and the survival mechanism after internalization were analyzed.In terms of tracing the source of food contamination, tracing methods such as microbiological detection methods and molecular biology traceability techniques were introduced, and the process, validation and application of contamination source tracing were analyzed.Finally, this paper proposed a series of prevention and control strategies, including strengthening hygiene management in food production, processing, storage and transport, improving public awareness of food safety and hygiene habits, timely detection and treatment of contaminated food, effective isolation and disinfection of the source of contamination, establishment of a sound emergency response mechanism for food safety, as well as strengthening communication and collaboration among government departments, enterprises and the public, with a view to reducing the risk of Salmonella to public health.

Key words： Salmonella; internalization mechanism; fruit and vegetable; food pollution source; prevention and control
