Abstract: Current Insights Regarding the Role of Farm Animals in the Spread of Antimicrobial Resistance from a One Health Perspective

Oct 21, 2022

Antimicrobial resistance (AMR) represents a global threat to both human and animal health and has received increasing attention over the years from different stakeholders. Certain AMR bacteria circulate between humans, animals, and the environment, while AMR genes can be found in all ecosystems. The aim of the present review was to provide an overview of antimicrobial use in food-producing animals and to document the current status of the role of farm animals in the spread of AMR to humans. The available body of scientific evidence supported the notion that restricted use of antimicrobials in farm animals was effective in reducing AMR in livestock and, in some cases, in humans. However, most recent studies have reported that livestock have little contribution to the acquisition of AMR bacteria and/or AMR genes by humans. Overall, strategies applied on farms that target the reduction of all antimicrobials are recommended, as these are apparently associated with notable reduction in AMR (avoiding co-resistance between antimicrobials).

Video: What Does 20 MILLION Hogs a Year Look Like?

?? The Multi-Plant System Processing 20 Million Hogs Annually in the Midwest JBS USA operates multiple large-scale pork processing facilities across the Midwest, including major plants in Iowa, Minnesota, and Indiana. Combined, these facilities have the capacity to process approximately 20 million hogs annually.

Each plant operates high-speed automated slaughter systems capable of processing up to 20,000 head per day, followed by fabrication lines that break carcasses into primals, sub-primals, and case-ready retail products.

Hog procurement is coordinated through electronic marketing platforms that connect regional contract finishing operations and independent producers to plant demand schedules. This digital procurement system allows for steady supply flow and scheduling efficiency across multiple facilities.

Processing plants incorporate comprehensive food safety systems, including pathogen intervention technologies, rapid chilling processes, and integrated cold-chain management. USDA inspection is embedded throughout the harvest and fabrication stages to ensure regulatory compliance and product integrity. Finished pork products — from bulk primals to retail-ready packaged cuts — are distributed through coordinated logistics networks serving domestic and export markets.
