Consumer demand for antibiotic-free beef and dairy has driven industry change. Understanding the welfare implications of antibiotic-free production ensures animals are not harmed by treatment restrictions.
Antibiotic-free production creates a genuine welfare tension when individual animals develop bacterial infections requiring treatment. The welfare case for antibiotic stewardship is strong: reducing prophylactic and growth-promotion antibiotic use addresses antimicrobial resistance without necessarily restricting therapeutic treatment. However, programs that prohibit all antibiotic use can create perverse incentives to delay or withhold treatment from sick animals to preserve market certification. The welfare-positive interpretation of antibiotic-free production requires clear commitment: animals that need antibiotics to avoid suffering receive them, and are then appropriately marketed through alternative channels rather than being left untreated.
