A recent study conducted by scientists from the Quadram Institute and the UK Health Security Agency has revealed that, despite cleaning, Listeria monocytogenes are able to persist in ready-to-eat (RTE) food production environments, supported by diverse bacterial populations that also remain stable over time.

Understanding the structure and function of biofilms is essential for developing effective strategies to control microbial biofilm formation, mitigate biofilm-related risks, and harness the beneficial properties of biofilms for various applications.

A recent study has demonstrated the protection that multispecies biofilms provide to Listeria monocytogenes against sanitizers, and could help inform more effective sanitation procedures in food processing environments.

A recent study reviewed the efficacy of environmentally friendly pathogen inactivation methods against Listeria monocytogenes biofilms in food production environments, specifically, electrolyzed water, plasma-activated water, ozone, and enzymes.

A recent study has demonstrated the extent to which defects on food contact surfaces in tree fruit packinghouses lowers the efficacy of sanitizers against Listeria monocytogenes biofilms.

Scientists from the U.S. Department of Agriculture’s Agricultural Research Service (USDA’s ARS) have provided new insight into the ability of Salmonella to survive and adapt in food processing facilities through interactions with environmental biofilms.

With each passing year, new and emerging technologies and techniques that have promise for advancing food safety are developed and validated. This article summarizes the top food safety innovations of 2023, based on audience interest. 

A recent study has demonstrated the efficacy of antimicrobial blue light technology for the inactivation of both dried cells and biofilms of Listeria monocytogenes on surfaces found in food processing environments. 

A project funded by the Center for Produce Safety has collected information about, validated, and evaluated the efficacy of the cleaning and sanitation practices for harvest equipment among blueberry harvesters and packers.

Pseudomonas biofilms can aid the survival of Listeria monocytogenes cells even after disinfection, according to a recent study.
