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.

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.

A recent analysis of a Canadian foodborne salmonellosis outbreak investigation has highlighted the importance of considering possible aerosolization of bacteria from drainage systems in restaurants as a risk factor for foodborne illness outbreaks.

Tebots Inc. has designed a UV disinfection station called POZ that addresses the limitations of existing devices that have prevented the technology’s adoption by the foodservice industry.

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. 

Ongoing research funded by the Center for Produce Safety aims to fill knowledge gaps about the efficacy of sanitizers and wash techniques used on peaches.

In this episode of Food Safety Matters, we are joined by Angela Anandappa, Ph.D., President and Founder of the Alliance for Advanced Sanitation, for a discussion about the Alliance's history and its current and future work, the fundamental role of sanitation in food safety, and the current challenges of the sanitation workforce.

Through sampling activities and whole genome sequencing (WGS) analysis, a recent research project funded by the Center for Produce Safety (CPS) revealed insights about the movement of L. monocytogenes across a processing facility, the persistence of the pathogen, and the efficacy of biocides and sanitation practices.

There is a growing trend of pathogenic outbreaks being traced to processed fruits, leading to industry players implementing more diligent control processes. This article discusses methodologies and regulations around fruit washing and sanitizing.
