Overuse or misuse of antimicrobials and improper disposal of antimicrobials in the agri-food system may result in food and environmental contamination and contribute to the global rise of AMR.

Citing concerns about antibiotic overuse in food-producing animals contributing to the spread of antimicrobial resistance (AMR), the petition calls for FDA to withdraw approvals for the routine use of medically important drugs for disease prevention.

The review summarized current knowledge about the potential contribution of foodborne bacteria and antibiotic resistance genes to the human gut resistome, suggesting the integration of gut microbiome and AMR data into risk assessment frameworks.

Per CDC and USDA-FSIS data, in 2023, Salmonella Infantis strain REPJFX01 accounted for 97 percent of S. Infantis isolates and 21 percent of all Salmonella recovered from chicken carcasses. This rising trend is closely aligned with an increase in human salmonellosis infections linked to REPJFX01.

The proportion of extensively drug-resistant isolates rose from 0 percent during 2011–2015 to 8.5 percent in 2023.

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.

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.

According to the researchers, the findings indicate that Salmonella persistence in food processing environments should not be attributed solely to disinfectant resistance. Proper implementation of cleaning and sanitization protocols alongside stringent hygiene practices remains critical.

Researchers found that the presence of nanoplastic particles can increase the expression of virulence and antimicrobial resistance (AMR) genes in Salmonella, and can also encourage biofilm formation.

In an analysis of domestic refrigerator swabs, researchers discovered complex microbial communities harboring foodborne pathogens and antimicrobial resistance (AMR). The findings also suggested that regular cleaning is possibly more important than temperature control in managing these communities.
