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.
To inform the broader third Intestinal Infectious Disease Survey (IID3), the UK Food Standards Agency (FSA) conducted a study to calculate burden estimates for four foodborne pathogens: enteropathogenic Escherichia coli (EPEC), sapovirus, hepatitis A virus, and Toxoplasma gondii.
According to internal FDA and CDC reports uncovered by NBC News and attorney Bill Marler, in November 2024, a multistate Escherichia coli outbreak linked to lettuce sickened 89 people, resulting in 36 hospitalizations and one death. Mention of the outbreak was not made public until the investigation was closed, nor were any details shared openly.
According to UK Health Security Agency (UKHSA) laboratory data on campylobacteriosis and non-typhoidal salmonellosis reports in England for 2014–2023, the total number of confirmed reports for both pathogens reached ten-year highs in 2023, and incidence for both also increased from the previous year.
The UK Health Security Agency (UKHSA) recently published its first annual report summarizing infectious disease trends, which noted increases in the incidence of infections by important foodborne pathogens like Escherichia coli, Salmonella, Listeria monocytogenes, Campylobacter, and norovirus.
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.
Researchers from CDC, FDA, and USDA trained an artificial intelligence (AI) machine learning model to conduct food source attribution for human cases of salmonellosis by analyzing whole genome sequencing (WGS) data for Salmonella isolates. The model showed promise, estimating that the majority of salmonellosis cases are caused by chicken and vegetables
The U.S. Centers for Disease Control and Prevention (CDC) has updated its estimates for the burden of domestically acquired foodborne illnesses in the U.S. caused by major pathogens. Norovirus was the leading cause of illnesses and hospitalizations, but Salmonella topped fatalities.
