Phage W5, isolated from poultry and livestock slaughterhouse effluent, significantly inhibited the growth of Salmonella in milk, pork, and eggs, and effectively prevented and eradicated biofilms on food-contact surfaces. The absence of virulence and antibiotic resistance genes supported its suitability as a food-grade biocontrol agent.
Although UV-C was effective against Salmonella, E. coli, and Listeria monocytogenes under most conditions, pathogen regrowth during refrigerated storage was significant. The findings suggest UV-C may be a useful post-harvest intervention when used in combination with other measures.
Using metagenomic sequencing and qPCR, the study analyzed bacteria from produce, chicken meat, and RTE deli meats sold at retail stores in Tennessee. A high abundance and diversity of antibiotic resistance genes were identified, potentially contributing to the persistence and spread of antimicrobial resistance (AMR) in the food supply.
The Canadian Food Inspection Agency (CFIA) recently published the findings from several food sampling and testing assignments for microbiological and chemical contaminants across a range of food categories. In general, the results were satisfactory.
The company says the recall is being issued “under protest” and “as a path forward,” while continuing to contest the epidemiological evidence provided by FDA.
Although FDA was unable to find a cause of contamination, a single supplier of the contaminated moringa powder was identified. Affected products, which were sold under the Rosabella brand and distributed by Ambrosia Brands LLC, have been recalled.
Responding to recent listeriosis outbreaks and recognizing that consumers do not always handle or cook ready-to-heat meals in accordance with package instructions, the Food Safety Authority of Ireland (FSAI) encourages businesses to implement recommended practices to better control L. monocytogenes.
Nearly all of the ill people interviewed reported consuming Raw Farm-brand raw dairy products. Testing and an onsite inspection of Raw Farm’s operation in California is ongoing. Raw Farm LLC has yet to issue a recall.
The Center for Produce Safety-funded project aims to generate practical guidance for produce growers, including improved sampling approaches to determine whether groundwater is influenced by surface water, and immediately actionable recommendations for mitigating microbial contamination and biofilms in irrigation systems.
Radio Frequency Company’s Macrowave Radio Frequency (RF) pasteurization systems have been fully validated for the treatment of rice flour utilized in infant formula, achieving a greater than 5-log reduction of important pathogens.
