Limited and judicious antimicrobial usage is considered the key to saving the success of human and veterinary medicine in treating infections. With the limited alternatives for antimicrobials, farm biosecurity (and herd management) is considered a promising tool to mitigate the non-judicious antimicrobial usage and to maintain animal health, production, and welfare. It involves measures to prevent the introduction and spread of infectious agents. By implementing farm biosecurity and herd management practices, disease outbreaks and the incidence of infectious diseases among farm animals can be reduced, potentially mitigating the need for antimicrobial treatments and the risk of antimicrobial resistance development.
