Comprehensive strategies for controlling Listeria monocytogenes biofilms on food‐contact surfaces

Abstract

AbstractListeria monocytogenes biofilms formed on food‐contact surfaces within food‐processing facilities pose a significant challenge, serving as persistent sources of cross‐contamination. In this review, we examined documented cases of foodborne outbreaks and recalls linked to L. monocytogenes contamination on equipment surfaces and in the food production environment, provided an overview of the prevalence and persistence of L. monocytogenes in different food‐processing facilities, and discussed environmental factors influencing its biofilm formation. We further delved into antimicrobial interventions, such as chemical sanitizers, thermal treatments, biological control, physical treatment, and other approaches for controlling L. monocytogenes biofilms on food‐contact surfaces. This review provides valuable insights into the persistent challenge of L. monocytogenes biofilms in food processing, offering a foundation for future research and practical strategies to enhance food safety.
