Although novel data streams like crowdsourced reports and social media posts may allow for rapid identification of foodborne illness events, they can also amplify false signals and lead to inaccurate self-reporting among consumers, as demonstrated in a recent survey.
An ongoing project funded by the Center for Produce Safety is investigating ways to increase the antimicrobial activity of food-grade waxes, which are commonly applied to fruit and vegetables to extend shelf life.
A laboratory study has provided new insights into the efficacy of peroxyacetic acid (PAA) and chlorine dioxide against Escherichia coli, Listeria monocytogenes, and norovirus in wash water during potato processing, and investigated cross-contamination risks in batch washing and water reuse scenarios.
A recent literature analysis of One Health-labeled studies described food safety’s representation as a research topic and its intersection with other facets of the One Health framework.
This episode of Food Safety Five discusses research on Listeria biofilms, including sanitizer efficacy and evolutionary insights, and on a persisting Escherichia coli strain in leafy greens. It also covers regulatory developments in the UK, Canada, and the UAE, as well as a potential U.S. ultra-processed foods (UPFs) definition.
A new study found high levels of antimicrobial resistance (AMR) among bacteria isolated from unpasteurized (raw) cow and sheep milk in Pakistan, with the potential to spread resistance genes to other bacteria through the food chain.
Researchers have developed a new, farm-to-fork quantitative microbial risk assessment (QMRA) model to evaluate the risk of Listeria monocytogenes contamination in fresh-cut cantaloupe.
A new study underscores that the level of consumer protection afforded by the food import control measures established in Commission Implementing Regulation (EU) 2019/1793 may not be proportionate to the resources invested.
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.
