Outline
Heat stress is a major environmental factor influencing the survival and pathogenicity of foodborne pathogens during food processing and storage. To survive adverse temperature conditions, these bacteria can generate heat stress responses through multi-level regulatory mechanisms, thereby maintaining cellular homeostasis and enhancing environmental adaptability. In recent years, with the deepening of related research, the molecular mechanisms gradually reveale of foodborne pathogens responding to heat stress. This review summarized the major heat stress response strategies of foodborne pathogens, with emphasis on cell envelope remodeling, gene expression regulation, protein homeostasis, antioxidant defense and metabolic adaptation. It also discussed the regulatory mechanisms underlying these responses. This review provides a theoretical basis for understanding thermal adaptation in foodborne pathogens and for developing strategies to improve food safety control.
