Listeria monocytogenes is an important food-borne pathogen, which could be detected in food, environmental and clinical samples. It contaminates food in any of the stages during production, processing, and storage, resulting in potential food safety issues. Traditional physical and chemical methods are effective in inhibiting the growth of L. monocytogenes and extending the shelf life of foods, however, the application of these methods usually results in undesirable damage to food quality. Recently, biological-based antimicrobial methods have attracted numerous attention due to their promising antimicrobial effects and ability to maintain food quality. The application of probiotics, as one of the biological based antimicrobial methods, has been widely reported that could effectively inhibit the growth of L. monocytogenes. In this review, human listeriosis and the current contamination situation of L. monocytogenes in foods are summarized first. Then, the effects of probiotics on the growth, biofilm formation, and virulence of L. monocytogenes in foods are discussed. Furthermore, the inhibitory mechanisms of the probiotics and their metabolites against L. monocytogenes are highlighted. With a comprehensive understanding of the bacteriostatic effect of the probiotics, the latest applications of probiotics in dairy products, meat products, and fresh products are presented and discussed.
李斯特菌是一种重要的食源性致病菌，可存在于食品、环境和临床样本中。它可以在生产、加工和储存的任何阶段污染食品，导致潜在的食品安全问题。传统的物理和化学方法可以有效抑制李斯特菌的生长，延长食品的保质期，然而，这些方法的应用通常会对食品质量造成不良影响。最近，基于生物的抗菌方法由于其有前景的抗菌效果和保持食品质量的能力而引起了广泛关注。益生菌作为一种基于生物的抗菌方法，其能够有效抑制李斯特菌的生长已被广泛报道。在本综述中，首先总结了人类李斯特菌病和食品中李斯特菌的当前污染情况。然后，讨论了益生菌对食品中李斯特菌生长、生物膜形成和毒力的影响。此外，还强调了益生菌及其代谢物对李斯特菌的抑制机制。通过全面了解益生菌的抑菌作用，介绍并讨论了益生菌在乳制品、肉制品和新鲜产品中的最新应用。
