摘要: 食源性致病菌在食品加工和贮藏相关胁迫诱导下容易产生交叉适应的现象,该现象导致预先受到亚致死胁迫的细菌对随后施加的其他胁迫产生耐受能力,使之在后续杀菌或抑菌处理中得以存活,造成食品安全潜在的风险。本文对常见食源性致病菌中产生交叉适应现象的现状以及影响因素、交叉适应现象的分子机制进行了综述,以期为减轻交叉适应现象从而增强食品微生物安全提供依据。

Abstract: Foodborne pathogenic bacteria are prone to cross-adaptation under food processing and storage-related stresses. This phenomenon leads bacteria subjected to sublethal stress develop tolerance to other stresses so that they can survive in subsequent sterilization or bacteriostatic treatment, posing a potential risk to food safety. This article reviews the current understanding of cross-adaptation in common foodborne pathogens, the factors influencing it and its molecular mechanism in order to provide a basis for reducing bacterial cross-adaptation to enhance microbial food safety.

Key words: foodborne pathogens; cross-adaptation; tolerance; molecular mechanism; food safety
