Listeria monocytogenes causes listeriosis, a rare foodborne disease with a mortality rate of 20%-30%. The elderly and immunocompromised are particularly susceptible to listeriosis. L. monocytogenes is ubiquitous in nature and can contaminate food-processing environments, posing a threat to the food chain. This is particularly important for ready-to-eat foods as there is no heat treatment or other antimicrobial step between production and consumption. Thus, occurrence and control of L. monocytogenes are important for industry and public health. Advances in whole-genome sequence technology are facilitating the investigation of disease outbreaks, linking sporadic cases to outbreaks, and linking outbreaks internationally. Novel control methods, such as bacteriophage and bacteriocins, can contribute to a reduction in the occurrence of L. monocytogenes in the food-processing environment, thereby reducing the risk of food contamination and contributing to a reduction in public health issues.
单核细胞增生李斯特菌可引发李斯特菌病，这是一种罕见的食源性疾病，死亡率为20%-30%。老年人和免疫功能低下者尤其易患李斯特菌病。单核细胞增生李斯特菌在自然界中无处不在，可污染食品加工环境，对食物链构成威胁。对于即食食品而言，这一点尤为重要，因为在生产和消费之间没有热处理或其他抗菌步骤。因此，单核细胞增生李斯特菌的发生与控制对食品行业和公众健康都至关重要。全基因组测序技术的进步有助于调查疾病暴发情况，将散发病例与暴发疫情联系起来，并在国际上关联不同的暴发疫情。新型控制方法，如噬菌体和细菌素，有助于减少食品加工环境中单核细胞增生李斯特菌的出现，从而降低食品污染风险，并有助于减少公共卫生问题。
