Contamination of Plant Foods with in a Province and Analysis of Its Traceability.

is an important zoonotic foodborne conditional pathogen. It is found in vegetables, dairy products, rice, and other foods, thereby greatly endangering human health. Investigations on contamination in China primarily focus on raw milk, dairy products, meat, and others, and limited research has been conducted on plant-based foodstuffs. The rapid development of sequencing technology and the application of bioinformatics-related techniques means that analysis based on whole-genome sequencing has become an important tool for the molecular-epidemiology investigation of . In this study, we investigated the contamination of in six types of commercially available plant foods from eight regions of a province. The molecular epidemiology of the isolated was analyzed by whole-genome sequencing. We aimed to provide fundamental data for the surveillance and epidemiology analysis of in food products in China. The rapid traceability system of established in this study can provide a basis for rapid molecular epidemiology analysis of , as well as for the prevention and surveillance of . Moreover, it can also be expanded to monitoring and rapid tracing of more foodborne pathogens.
