Since 2000, outbreaks have been attributed to fresh, soft Queso Fresco-type cheeses made from pasteurized milk, which have been contaminated by L. monocytogenes after pasteurization
This article presents the key findings of outbreak investigations from 2014–2021 that have been linked to the consumption of fresh, soft queso fresco-type cheeses in the U.S. The authors outline some of the specific circumstances that small manufacturers of all cheeses may encounter in an effort to provide lessons learned and highlight available resources.
Using whole genome sequencing (WGS), researchers from the University of Johannesburg have identified a trend of nonpathogenic Listeria strains developing concerning characteristics, such as virulence and stress resistance. Like the pathogenic L. monocytogenes, the “harmless” strains L. innocua and L. welshimeri are common to food processing facilities.
In this episode of Food Safety Matters, we talk to Jovana Kovacevic, Ph.D., Associate Professor and Food Safety Extension Specialist at Oregon State University’s Food Innovation Center (OSU’s FIC). Dr. Kovacevic discusses her work at FIC, which includes developing educational materials for industry related to the Food Safety Modernization Act (FSMA), and conducting research on Listeria monocytogenes in an effort to better control the pathogen.
The U.S. Food and Drug Administration (FDA) has worked with the U.S. Environmental Protection Agency (EPA) to update the protocol for the development and registration of antimicrobial treatments for preharvest agricultural water, removing Listeria monocytogenes from the organism test panel.
The European Center for Disease Control and Prevention (ECDC) has released 2021 epidemiological reports for common foodborne illnesses listeriosis, campylobacterosis, hepatitis A infection, Shiga toxin-producing Escherichia coli (STEC) infection, salmonellosis, and yersinosis.
Failure to plan, design, implement and upkeep good Safety Management Systems (FSMSs)along with a strong, positive food safety culture often leads to compromised food safety and subsequent foodborne illness outbreaks at food processing organizations. This phenomenon is observed with a much higher incidence in medium-and small-sized food companies. In this article, ice cream listeriosis outbreak case studies provide context for the importance of PRPs, GMPs, and process control in preventing foodborne illness outbreaks.
SmartWash Solutions has announced its new EPIC Panel Sterilight, a patent-pending product designed to safely and automatically kill Listeria monocytogenes and other pathogens inside control panels, which is an often-overlooked source of cross-contamination in the food industry.
The Joint FAO/WHO Expert Meeting in Microbial Risk Assessment (JERMA) convened in response to a Codex Alimentarius Committee request to develop microbiological risk assessment models for Listeria monocytogenes, and to provide recommendations to inform possible future revisions to Codex guidelines on hygienic controls for L. monocytogenes.
A recent case study from the Sapienza University of Rome examined the surveillance of foodborne pathogens through a One Health lens in Europe, with a specific focus on the One Health European Joint Program (OHEJP) MATRIX Project framework.
A multistate outbreak of Listeria monocytogenes infections associated with meat and cheese from deli counters has resulted in 13 hospitalizations, one death, and one miscarriage. The foodborne illness outbreak is under investigation.
