Antimicrobial resistance (AMR) driven partly by livestock antibiotic use threatens the future of animal disease treatment, creating long-term welfare risks that antibiotic stewardship aims to address.
Antimicrobial resistance is a long-term welfare crisis in slow motion. As antibiotic effectiveness diminishes, the infections that are currently treatable become progressively harder to cure. Animals with resistant bacterial infections suffer for longer and have worse outcomes. The welfare case for antibiotic stewardship in livestock is therefore not just about human public health - it is directly about the future ability to relieve animal suffering. The UK's voluntary stewardship programme has achieved remarkable reductions without mandated restrictions, demonstrating that industry-led responsibility can work when metrics are transparent and publicly reported. The EU's mandatory ban on prophylactic mass medication formalises what good practice already requires. The welfare argument and the stewardship argument are the same argument.
