Approach Choices for Antimicrobial Use Reduction in European Food Animal Production

Summary Reducing antimicrobial use (AMU) stands as a pivotal global strategy in combating antimicrobial resistance (AMR) within the realm of food animal production. We conducted an extensive review of the distinct approaches employed in managing AMU reduction within the United Kingdom, Denmark and the Netherlands. Our analysis delved into the reform processes, emphasising the roles played by government, the general public and key stakeholders throughout the supply chain. Furthermore, we examined the impacts of these approaches on AMU, AMR and the economic landscape of food animal production. In all three countries, these reforms have been anchored in the reduction and judicious utilizsation of Critically Important Antimicrobials (CIAs) for veterinary use. These efforts have yielded significant outcomes, particularly in the reduction of CIA use. In utilising a voluntary approach to AMU reduction, the active involvement of government bodies, consumers and supply chain leaders, notably supermarkets, has proven to be pivotal. In terms of execution, these countries have adopted varied management strategies, including voluntary, regulatory and hybrid approaches, championed by farmers, government agencies and veterinarians, respectively. These approaches have yielded diverse impacts, both in terms of their potential for reduction and their influence on farm performance.
