Science, Not Simplicity, Should Drive Antimicrobial Use in Livestock

The use of antimicrobials in livestock has sparked significant debate, with many reducing the issue to the oversimplified idea that “less is better.” However, for pork producers and veterinarians, antimicrobials are essential for maintaining animal health and well-being.

As a swine veterinarian with years of experience, and now as the Food Policy Director for the National Pork Producers Council (NPPC), my focus has always been on ensuring the best care for livestock.

The Role of Antimicrobials in Animal Care

Antimicrobials are critical tools that veterinarians use to protect animal health, similar to how doctors treat human patients. A recent United Nations proposal sought to reduce on-farm antimicrobial use globally by 30% and place limits on specific antimicrobials in animal agriculture.

This policy was not grounded in scientific evidence and threatened veterinarians’ ability to provide proper care for livestock.

Fortunately, in September, the U.N. General Assembly rejected this proposal. Instead, they emphasized the importance of investing in stewardship programs and strengthening the role of veterinarians in managing farm practices.

This outcome was a win for U.S. pork producers and reinforced that scientific approaches are essential when addressing antimicrobial use.

A Science-Based Approach is Essential

Efforts to impose one-size-fits-all antimicrobial reduction targets oversimplify the issue. Livestock care is complex, and blanket policies do not account for the diverse needs of different farms.

The United Nations’ decision to support a science-based approach ensures that veterinarians can continue to make informed decisions for herd health, without unnecessary limitations.

Global Discussions and the U.S. Pork Industry’s Commitment

This year, I had the privilege of representing the NPPC on three global platforms: a U.N. hearing, USDA comments, and the World Antimicrobial Resistance Congress.

On these stages, I advocated for responsible antimicrobial use practices and highlighted the U.S. pork industry’s dedication to working with veterinarians.

Programs like Pork Quality Assurance Plus ensure that farm employees are trained in the judicious use of antimicrobials, supporting the industry’s commitment to stewardship.

Progress in Combating Antimicrobial Resistance

While antimicrobial resistance remains a global health challenge, progress is being made. According to the U.S. Food and Drug Administration, the sale of medically important antimicrobials has consistently decreased since 2017, with a 36% drop reported in 2022 compared to 2015. The U.S. pork industry remains committed to advancing these efforts through responsible practices.

Collaboration is Key to Success

There is no universal solution to combat antimicrobial resistance. The path forward requires collaboration among all stakeholders — from animal health to human health professionals. By using antimicrobials responsibly and working together, we can address this global challenge effectively.
