Glyphosate may fuel drug-resistant bugs spreading from farms to clinics
Argentine researchers found bacteria from a wetlands site never sprayed with glyphosate still developed tolerance to the weedkiller, and hospital drug-resistant strains survived high doses of glyphosate in tests. Genetic analysis linked the wetlands bacteria to hospital pathogens, suggesting glyphosate exposure and runoff could help spread resistance genes between farms and clinics, raising regulators’ and wastewater managers’ attention to pesticide testing for antibiotic-resistance side effects.
