Abstract:It is of great practical significance to carry out research on prevention and control of foodborne pathogenic bacteria to ensure food safety.As a self-protection mechanism for bacteria to adapt to the bad environment，food borne pathogenic bacteria can adhere to the surface of food raw materials and various food processing equipment in the process of food production and processing to form biofilm，which increases the difficulty of disinfection and cleaning，and brings serious hidden danger and harm to food safety.Therefore，how to effectively remove bacterial biofilm has become a research hotspot in the field of food safety.Combined with the formation process and regulation mechanism of bacterial biofilm，this study systematically analyzed and summarized the current situation of detection and removal methods of bacterial biofilm，which provided a comprehensive recognition for the effective control of bacterial biofilm and elimination of food safety risks caused by biofilm.This study could provide a reference for researchers to solve the food borne microbial pollution caused by bacterial biofilm，which was of great significance to ensure food safety.
