any organisations such as the U.S. Center for Disease Control and Prevention consider this issue to be a global public health concern. This is especially relevant to the livestock industry


as misuse of antibiotics beyond their intended purposes can contribute to AMR increases.


Causes of AMR Paige Gott, senior ruminant technical manager for Biomin America, explains that antimicrobial resistance occurs when


microorganisms, like bacteria, are no longer affected by antimicrobial substances that previously worked to inhibit their growth or killed them entirely. “Food animal agriculture has been suggested as a potential contributor in the development and spread of AMR for a few reasons,” she explains, “including historic use of low-dose antibiotics for production purposes (e.g., growth promotion and improved feed efficiency) and the potential spread of AMR bugs to humans via the food chain.” Various organisations all over the world have established regulations that allow them to oversee and control the use of different antimicrobial treatments in animals to decrease the
