A national study led by the UK Food Standards Agency (FSA) found concerning increases in antimicrobial resistance (AMR) among poultry-associated Campylobacter isolates. Source attribution modeling predicted that chicken meat is by far the most dominant source of human campylobacteriosis cases.
A high proportion of Campylobacter and Salmonella from food-producing animals across Europe are resistant to antimicrobials that are important to human medicine. Escherichia coli resistance to last-resort carbapenems is growing.
Potentially offering an effective natural control strategy in food production, a study demonstrated the ability of select essential oils to inactivate multidrug-resistant Campylobacter isolated from poultry and investigated the mechanisms of antibacterial action, while highlighting variability in essential oil potency and species-specific susceptibility.
By increasing the understanding of a molecular “weapon” used by the foodborne pathogen, the project, led by the London School of Hygiene and Tropical Medicine, will support the development of new antimicrobials and vaccine targets to reduce transmission through the food chain.
According to the newly published European Union One Health 2024 Zoonoses Report, the number of foodborne illnesses and outbreaks reported in the EU are on an upward trend. Notably, listeriosis cases with severe outcomes have risen.
This episode of Food Safety Five discusses hoses as reservoirs for biofilms in food processing facilities, the presence of Listeria monocytogenes and Campylobacter on retail beef and chicken, a new Salmonella serovar database, and microplastics release from food contact materials.
New research has demonstrated a low overall prevalence of Campylobacter on retail chicken meat; however, recovered C. jejuni strains did not match known poultry-associated genotypes, suggesting the need for sensitive detection methods and expanded genomic surveillance.
A CDC analysis of multistate foodborne illness outbreak investigation data for 2023 reveals the foods and pathogens that caused the greatest number of outbreaks and illnesses. A single salmonellosis outbreak linked to cantaloupe accounted for 407 illnesses.
USDA Food Safety and Inspection Service (USDA-FSIS) laboratories now use an improved enrichment method for Campylobacter in poultry meat samples, which reduced enrichment incubation time by half, and shaved a day off of reporting times for results.
Per Trace One’s analysis of FDA National Antimicrobial Resistance Monitoring System (NARMS) data, the U.S. states with the highest levels of Salmonella and Campylobacter contamination in retail meat are Georgia, South Carolina, and Tennessee.
