Welfare Implications of Antibiotic Use in Livestock

Routine antibiotic use in livestock farming has complex welfare implications — masking disease in poor conditions while also creating resistance risks.

Key Facts

Approximately 73% of global antibiotic use occurs in food-producing animals, not humans
Growth-promoting antibiotic use is now banned in the EU and restricted in the US
Routine prophylactic antibiotics enable high-density farming that would otherwise cause disease outbreaks
Antibiotic resistance threatens both human and animal health systems globally
Farms that reduce antibiotic use by improving welfare conditions show equivalent or better outcomes

Welfare Considerations

The relationship between antibiotics and animal welfare is complex. On one hand, antibiotics treat illness and reduce suffering in sick animals. On the other, routine preventive use enables farming systems with conditions so poor that disease outbreaks are inevitable without medication — effectively subsidizing welfare failures with pharmaceuticals. Reducing antibiotic use in agriculture therefore requires improving underlying welfare conditions, creating a direct link between antimicrobial stewardship goals and animal welfare reform. Farms that transition to higher welfare systems consistently reduce antibiotic use as a natural consequence.

What You Can Do

Choose meat and dairy products from farms certified to low-antibiotic-use standards
Support policies that restrict routine preventive antibiotic use in farming without requiring welfare improvements
Learn about the connection between antibiotic stewardship and welfare improvement to build cross-sector coalitions
Advocate for higher welfare standards as the foundation of antibiotic reduction programs
