Initially launched in 2024, the investigation was reopened in April 2025. Whole genome sequencing (WGS) analysis confirmed that the strain of Listeria found at Fresh & Ready Foods LLC matches the strain of Listeria causing illnesses in this outbreak.

In this episode of Food Safety Matters, we speak to Dr. Edward Dudley, Director of the E. coli Reference Center and Professor of Food Science at Penn State University, about the potential for wastewater monitoring to aid foodborne pathogen surveillance and bolster foodborne illness reporting. 

This episode of Food Safety Five discusses newly published CDC data about the pathogens causing foodborne illness and contributing factors of outbreaks, as well as research by CDC, USDA, and FDA scientists exploring the use of AI analysis of whole genome sequencing data for foodborne illness source attribution.

The European Commission published a FAQ document to clarify the requirements of Regulation (EU) 2025/179, which mandates whole genome sequencing (WGS) testing and data reporting for important foodborne pathogens when suspected to be associated with a foodborne illness outbreak.

A new study by USDA researchers has shown that long-read whole genome sequencing (WGS) could detect Salmonella attachment to food-contact surfaces earlier than traditional culture-based methods, allowing for sanitation interventions to be applied before the maturation of robust and difficult-to-remove biofilms.

The EU has adopted a new regulation requiring Member States to conduct whole genome sequencing (WGS) on the isolates of five important pathogens during the investigations of foodborne illness outbreaks, and sets data-sharing parameters.

Between 2017 and 2019, Canadian public health laboratories transitioned to whole genome sequencing (WGS) for foodborne illness outbreak surveillance. A recent study shows the positive impact of this transition of national outbreak detection and response for important foodborne pathogens. 

A survey of 200 international food processors provides insight into which food safety technologies are being adopted and their effects on daily operations. Part 3 explores the impact and need for further development of testing technologies, focusing on responses from participants outside of North America.

Published in CDC’s Emerging Infectious Diseases, one of the largest-ever whole genome sequencing (WGS) analyses of Campylobacter in Africa found antimicrobial resistance (AMR) in 75 percent of human and poultry isolates from Tanzania and Kenya.

Penn State University researchers have demonstrated the usefulness of wastewater monitoring for foodborne pathogen surveillance, after successfully isolating Salmonella from wastewater samples and linking them to clinical isolates from an existing foodborne illness outbreak.
