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

The U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS) has updated its Best Practices Guidance for Controlling Listeria monocytogenes in Retail Delicatessens.

The U.S. Food and Drug Administration (FDA) recently released the findings of a sampling assignment that collected and tested ready-to-eat (RTE) dips and spreads with the aim of determining the presence of Listeria monocytogenes and Salmonella.

Wageningen University Food Safety Research recently launched a four-year project with the goal of developing an early warning system to detect the presence of mycotoxins in European cereal grains.

In this bonus episode of Food Safety Matters, we speak with two poultry science experts about what industry can do to reduce the presence of Salmonella in poultry products in light of the U.S. Department of Agriculture’s (USDA’s) recently proposed requirements that would consider Salmonella an adulterant in poultry.

The U.S. Department of Agriculture’s Agricultural Research Service (USDA’s ARS) has launched the Salmonella Grand Challenge—a new, nationwide initiative that brings together a group of elite scientists from different specialties to fight salmonellosis. The scientists will integrate their research to learn more about Salmonella risks to meat and poultry products, which will then inform the development of monitoring tools for meat and poultry producers to prevent Salmonella contamination.

The U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS) has released an updated Guideline for Controlling Salmonella in Swine Slaughter and Pork Processing Establishments.

Salmonella infection is one of the most commonly reported causes of foodborne illness, resulting in over 80 million cases of foodborne salmonellosis each year globally.

Approximately 40 percent of foodborne illness outbreaks associated with retail food establishments during 2017–2019 were caused by an infectious employee, according to the U.S. Centers for Disease Control and Prevention (CDC).

A recent study has demonstrated the ability of Listeria monocytogenes to develop persister cells under produce packinghouse conditions, as well as persisters’ susceptibility to chlorine treatment where antibiotics fail.
