Antimicrobial Resistance and Farm Animal Welfare

Antibiotic resistance driven partly by livestock use threatens both animal and human health; addressing overuse requires welfare improvements that reduce the need for treatment.

Key Facts

Global livestock antibiotic use exceeds human use, accounting for over 70% of total consumption in some countries
Overuse of antibiotics in intensive systems selects for resistant bacteria affecting both animals and humans
Many countries have banned routine antibiotic growth promoters, reducing use without production losses
Higher-welfare systems with lower stocking densities typically require less antibiotic treatment
Welfare improvements that reduce disease incidence simultaneously reduce antibiotic dependency

Welfare Considerations

Intensive livestock systems often use antibiotics as a substitute for good welfare: overcrowded, stressful conditions cause disease that is then suppressed with medication rather than prevented through improved husbandry. This creates a cycle of welfare compromise and antibiotic dependency. Farms that improve housing space, ventilation, and management typically reduce antibiotic use dramatically. The welfare and antimicrobial resistance crises are thus deeply linked, and addressing one helps address the other.

What You Can Do

Choose meat and dairy products from certified reduced-antibiotic or antibiotic-free producers
Advocate for restrictions on prophylactic antibiotic use in intensive livestock systems
Support research into welfare-based approaches to disease prevention in farming
