New guidelines from the US Food and Drug Administration (FDA) aim to curb the large-scale nontherapeutic use of antibiotics by livestock producers, in an effort to reduce the emergence of antibiotic resistance.
A growing body of evidence suggests that large-scale use of antibiotics in livestock production contributes to the emergence in animals of resistant strains of bacteria, which may be transmitted to humans. This has led to increasing calls for the more judicious veterinary use of antibiotics. One practice in particular has been targeted—the long-term use of low-dose antibiotics to promote the growth of healthy food animals.
