A Center for Produce Safety-funded proof-of-concept study is exploring a novel, high-throughput capture and concentration method for hepatitis A virus in fruit wash water, which uses magnets and hydrogel nanoparticles. It could be added to existing FDA and ISO digital PCR assay workflows, potentially reducing false positives.
Using a specially designed framework, researchers from the University of Illinois Urbana-Champaign analyzed and characterized how food businesses are responding to the emerging patchwork of disparate state regulations on additives, labeling, and manufacturing. They cautioned about the unintended consequences borne by the complexity of complying with individualistic state-level policies.
Harmonization of precautionary allergen labeling (PAL) requires the acceptance of reference doses for priority allergens. A new study found that PAL based on specific FAO/WHO-recommended thresholds would only elicit mild to moderate reactions in a small proportion of the allergic population.
A study demonstrated the toxic effects of exposure to per- and polyfluoroalkyl substances (PFAS) in worms—but not all PFAS were found to be equally toxic, and not all worms experienced the same harms. Identifying which genes cause PFAS susceptibility in both worms and humans could speed up PFAS testing and regulation.
Researchers from UCLA have found that chewing gum can release hundreds to thousands of microplastic particles per piece into saliva—no matter if the gum is made of synthetic or natural, plant-based polymers.
Researchers from the University of Córdoba
in Spain have developed a model for predicting the growth of Listeria monocytogenes in artisanal cheeses, which will be especially useful to producers that must demonstrate compliance with recently expanded EU regulations for controlling the pathogenin ready-to-eat (RTE) foods.
A study from the University of Georgia’s Center for Food Safety suggests a synergistic effect between antimicrobial blue light treatment and low concentrations of sanitizers commonly used in industry, finding enhanced inactivation of Listeria monocytogenes on food contact surfaces.
A project funded by the Center for Produce Safety is developing an identification and deterrent system for high-risk birds in produce fields based on sound surveillance and artificial intelligence (AI). The tool would automatically deploy interventions to drive away birds that are more likely to spread foodborne pathogens.
A recent study identified gaps in currently used food safety training and certification materials for food handlers, and tested the effectiveness of a supplementary training toolkit in improving knowledge and confidence outcomes of low-literacy employees.
In a first-of-its-kind study analyzing large population-level datasets, researchers from the University of Southern California’s Keck School of Medicine estimated that communities exposed to per- and polyfluoroalkyl substances (PFAS) -contaminated drinking water experience up to 33 percent higher incidence of certain cancers.
