The US Food and Drug Administration (FDA) is taking a step toward reducing the use of medically important antibiotics as growth promoters in livestock, but the proposal hinges on the cooperation of antibiotic manufacturers.
Companies that produce antibiotics for use in livestock are being asked to voluntarily change the labels of their drugs to indicate they are no longer FDA-approved for growth promotion and that a veterinarian must oversee their use. If they do, it would become illegal for livestock producers to routinely add subtherapeutic doses of medically important antibiotics to animal feed to promote faster growth.
