A UK-based study, led by Quadram Institute researchers, underscores the limitations of traditional enumeration methods for foodborne pathogen surveillance and highlights the need for whole genome sequencing (WGS) to better assess the food safety risk posed by commensal or opportunistic Escherichia coli lineages.
Wageningen University researchers conducted an experimental evolutionary study to explore the genetic and phenotypic mechanisms that drive the enhanced biofilm formation ability of evolved L. monocytogenes strains, identifying the overexpression of a certain protein as a key contributor.
Despite increased regulatory efforts, Salmonella outbreaks linked to chicken remain a significant public health threat in the U.S., reaffirms a new study by CDC and USDA-FSIS researchers. The majority of outbreaks involved chicken parts and five serotypes of concern.
An analysis conducted by Cornell University researchers sought to better understand the genomic characteristics associated with an important reoccurring, emerging, and persistent (REP) Salmonella strain, S. Infantis REPJFX01, to help inform targeted interventions.
A recent study sought to better understand the ability of Listeria monocytogenes biofilms on stainless steel surfaces to withstand common industry sanitizers, chlorine and PAA, using strains and temperature conditions relevant to the fresh leafy greens supply chain.
An ongoing Center for Produce Safety-funded study is investigating the factors contributing to the persistence of a reoccurring, emerging, and persisting (REP) Escherichia coli O157:H7 subtype associated with leafy greens foodborne illness outbreaks, with the goal of developing a risk assessment tool for growers.
A new Southern California-based study found that food safety may play a role in UTIs. Genomic analysis of Escherichia coli isolates from UTI patients and retail meats linked 18 percent of UTIs to E. coli strains of animal origin, suggesting foodborne transmission.
Although this severe Escherichia coli strain is already prevalent in countries with less robust food safety and sanitation systems, as climate change becomes more extreme and cuts are made to food safety monitoring and infrastructures, it is becoming a growing threat to developed countries as well, researchers warn.
A review published by EFSA concludes that, while there is clear evidence of microplastic release from food contact materials (FCMs), the actual quantities are likely lower than many studies suggest, and current evidence does not support reliable exposure estimates. Nanoplastics data remain insufficient.
A 2024 European foodborne illness outbreak caused by a rare Salmonella serotype, linked to leafy greens grown near a buffalo farm, exposed gaps in biosecurity, surveillance, and data transparency across the agri-food system.
