A Review of the Biofilm Formation and Transfer of Listeria monocytogenes in the Food Environment and Prevention and Control Measures for It

Listeria monocytogenes is a major foodborne pathogenic bacterium. Currently, there is a widespread concern over the issue that the formation and transfer of L. monocytogenes biofilm in the food environment can pollute food. Prevention and control of L. monocytogenes biofilm to prevent the food environment from biofilm contamination is important for guaranteeing food safety. In this article, the biofilm formation ability of L. monocytogenes sampled from the food environment is summarized. Moreover, the factors contributing to L. monocytogenes biofilm formation and transfer are reviewed. Finally, this review also gives an overview of the approaches currently available for the prevention and control of L. monocytogenes biofilm formation. We believe that further studies should be carried out by using more representative L. monocytogenes strains and simulating more realistic cases in order to better understand biofilm formation and transfer and to provide a theoretical basis for easier elimination of L. monocytogenes biofilm. Furthermore, the formation mechanism of L. monocytogenes biofilm, as well as the mechanism by which the relevant factors affect L. monocytogenes biofilm, should also be studied in order to provide a basis for the implementation of efficient prevention and control measures for L. monocytogenes biofilm.
