Outbreaks caused by highly industrialized food companies are characterized by cross-border, trans-regional, rapid and unpredictable, related to serious disease and economic burden. A cluster of cases with monophasic salmonella enterica serovar Typhimurium ST34 infection suspected to be associated with consumption of contaminated chocolate products have been reported in several Europe countries since December 2021. After retrospective investigations, the buttermilk circuit in the Belgian factory was suspected to be the point of origin of the contamination. This outbreak could provide a reference for the risk management of foodborne pathogens contamination in China. The objective of this paper was to summarize the process and characteristics of the outbreak of monophasic S. Typhimurium caused by contaminated chocolate products, analyze the characteristics of ST34 monophasic S. Typhimurium and the microbial management measures in the process of chocolate products, and systematically discuss the suggestions for the risk management of foodborne pathogens contamination and countermeasures for the rapid development of industrialization of food enterprises in China, in order to provide scientific and technological support for the prevention and control, prediction and early warning of sudden cases in China.
食品产业高度工业化导致的食源性疾病暴发呈跨国界、跨区域、进展快、难预测等特点，造成严重的疾病和经济负担。自2021年12月以来，欧洲多国报告了疑似食用受污染巧克力产品的ST34型单相鼠伤寒沙门菌聚集性感染病例。经回溯性调查，比利时涉事工厂的酪乳管道高度疑似为本次单相鼠伤寒沙门菌污染的源头，此次事件为我国食源性致病菌污染风险管理提供了借鉴和参考。本文梳理了此次单相鼠伤寒沙门菌污染巧克力产品所致暴发事件的过程和特点，分析单相鼠伤寒沙门菌的特征以及巧克力产品生产过程中的微生物管理措施，并基于本次暴发事件系统论述我国食品企业工业化快速发展过程中的食源性致病菌污染风险管理建议及对策，以期为我国食源性疾病暴发事件的防控、预测预警提供科学技术支撑。.
