The LmRNA project will explore the genetic and physiological responses of Listeria monocytogenes biofilms to dairy environment conditions to support the development of improved strategies for preventing antimicrobial resistance (AMR).

Whole genome sequencing (WGS) analyses have revealed pervasive Listeria monocytogenes strains to be an issue throughout the Norwegian food system, and researchers hypothesize that genetics may factor into which strains survive and spread in food production environments. 

The U.S. Centers for Disease Control and Prevention (CDC) has summarized its investigations of possible multistate outbreaks caused by Salmonella, Shiga toxin-producing Escherichia coli (STEC), and Listeria monocytogenes in 2017–2020. 

Researchers at the University of Georgia are developing a biosensor-based rapid diagnostic test for Listeria monocytogenes in food.

The Center for Produce Safety (CPS) has published a summary of the 2022 CPS Symposium, highlighting several crucial food safety findings related to Cyclospora, Listeria, biofilm control, sanitization methods, and more.

A recent Danish report outlines the foodborne illness outbreaks that occurred in Denmark in 2021, which nearly doubled from 2020. 

The U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS) has published its annual report on FSIS Foodborne Illness Outbreak Investigations for Fiscal Year 2021 (FY 2021) and key after-action reviews.

The Swiss Association of Cantonal Chemists recently published an inspection report that revealed deficiencies in controls for Listeria monocytogenes among food businesses. 

A recently published review examines the history of foodborne illness outbreaks caused by Listeria monocytogenes in the UK, challenges that food manufacturers face when dealing with the pathogen, and potential future research and strategies related to the pathogen. 

A dataset on Listeria monocytogenes has been compiled from over 1,400 genomes collected across 19 European nations to better understand the pathogen’s genetic makeup and adaptation in different ecological niches.
