The relationship between farm animal welfare conditions, antibiotic use, and the global public health crisis of antimicrobial resistance.
Antimicrobial resistance creates a powerful alignment between animal welfare and human public health that advocates should not underuse. The scientific connection is well-established: poor welfare conditions compromise immunity and increase disease susceptibility, driving antibiotic use that in turn creates resistance. Better welfare reduces antibiotic dependency, slowing resistance development. This means every farm welfare improvement is simultaneously a public health investment. The Denmark case demonstrates that dramatic antibiotic reduction is achievable alongside welfare improvement — providing an evidence-based model that other countries can adopt without welfare-production trade-offs.
