Antibiotic use in livestock production is linked to antibiotic resistance that threatens both human and animal welfare, creating alignment between welfare improvement and public health.
The connection between livestock welfare and antibiotic resistance creates a powerful alignment between animal welfare improvement and human health protection. Animals kept in poor welfare conditions with high disease burden require more antibiotic treatment, driving resistance. Animals in high-welfare conditions with lower disease incidence require less treatment. Improving livestock welfare is therefore simultaneously an animal welfare intervention and a public health intervention. This alignment provides a strong policy argument for welfare investment that extends beyond animal ethics to human health security.
