Pork supply chains may be shaping the global spread of drug-resistant Salmonella

A global genomic analysis and field sampling in China suggest that the riskiest points for drug-resistant Salmonella may emerge after pigs leave the farm. https://www.news-medical.net/news/20260730/Pork-supply-chains-may-be-shaping-the-global-spread-of-drug-resistant-Salmonella.aspx In a recent study published online as an unedited 'Article in Press' in the journal npj Science of Food, researchers investigated the association between pork supply chains and the evolution of antimicrobial resistance in Salmonella enterica. The study integrated global genomic datasets (both human and swine; n = 129,136) with prospective field sampling collected along an integrated pork supply chain in Guangdong, China (n = 1,114), to assess whether specific supply-chain stages were associated with Salmonella contamination and enrichment of resistance genes.
