Abstract

, a causative agent of listeriosis, is a major foodborne pathogen. Among pathogens, stands out for its unique ecological and physiological characteristics. This distinct lifestyle of has a significant impact on food safety and public health, mainly through the ability of this pathogen to multiply at refrigeration temperature and to persist in the food processing environment. Due to a combination of these characteristics and emerging trends in consumer preference for ready-to-eat and minimally processed food, there is a need to develop effective and sustainable approaches to control contamination of food products with . Implementation of an efficient and reliable control strategy for must first address the problem of cross-contamination. Besides the preventive control strategies, cross-contamination may be addressed with the introduction of emerging post packaging non-thermal or thermal hurdles that can ensure delivery of a listericidal step in a packed product without interfering with the organoleptic characteristics of a food product. This review aims to present the most relevant findings underlying the distinct lifestyle of and its impact on food safety. We also discuss emerging food decontamination technologies that can be used to better control .

摘要

李斯特菌,一种引发李斯特菌病的病原体,是一种主要的食源性病原体。在众多病原体中,李斯特菌因其独特的生态和生理特性而引人注目。这种独特的生活方式对食品安全和公共健康有重大影响,主要是因为这种病原体能够在冷藏温度下繁殖,并在食品加工环境中持续存在。由于这些特点的结合以及消费者对即食和低加工食品偏好的新兴趋势,需要开发有效和可持续的方法来控制食品中李斯特菌的污染。实施李斯特菌有效且可靠的控制策略,首先必须解决交叉污染的问题。除了预防性控制策略外,还可以通过引入新兴的包装后非热或热处理障碍来解决交叉污染问题,这些障碍可以确保在包装产品中进行杀菌步骤,而不会干扰食品的感官特性。本综述旨在介绍李斯特菌独特生活方式及其对食品安全影响的最相关研究结果。我们还讨论了新兴的食品消毒技术,可用于更好地控制李斯特菌。
