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.
The European Food Safety Authority (EFSA) recently published a scientific opinion that identified the most relevant persistent microorganisms in food and feed production environments to be Salmonella, Listeria monocytogenes, and Cronobacter sakazakii, as well as risk factors and interventions associated with these pathogens.
The U.S. Centers for Disease Control and Prevention (CDC) recently published three new factsheets on Listeria monocytogenes for vulnerable populations.
Two complimentary studies funded by the Center for Produce Safety (CPS) are using genomic sequencing technology to examine how storage conditions affect microbial growth on pears, with a focus on Listeria monocytogenes.
A European multi-country foodborne illness outbreak of Listeria monocytogenes, in which ready-to-eat (RTE) fish is the suspected cause, has resulted in two deaths.
The Interagency Food Safety Analytics Collaboration (IFSAC)—a joint effort between FDA, CDC, and USDA-FSIS—has published its 2021 report on foodborne illness source attribution for Salmonella, Escherichia coli O157, and Listeria monocytogenes.
A recent studyhas 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 recent study carried out environmental monitoring programs (EMPs) for Listeria monocytogenes at three food production facilities in Japan with the aim of developing EMPs that are relevant to Japanese food businesses and to encourage more widespread adoption of EMPs.
Implementing an effective Listeria environmental monitoring program enables knowledge of where Listeria can enter, harbor, and move through a facility, which is the first step toward keeping the pathogen on the run and not allowing it to impact production surfaces or finished product.
State and local health departments in Washington are investigating five cases of foodborne illness caused by Listeria monocytogenes in Western Washington, three of which have resulted in death. Whole genome sequencing (WGS) has indicated a common source of infection.
