Antimicrobial resistance poses one of the biggest threats to public and animal health.1 Of all antibiotics sold in the United States, approximately 80% are sold for use in animal agriculture.2
Although measures have been taken to reduce the non-judicious use of antimicrobials in livestock production, using these for non-therapeutic purposes remains prevalent in many regions across the world.
A well-known meta analysis reviewed 27 studies across multiple countries and showed that increased biosecurity measures were the biggest factor associated with lower levels of antimicrobial use.3
