Tracking Resistance: The Role of AMR Surveillance

Tracking resistance, the whole of AMR surveillance. Antimicrobial resistance or AMR is a global challenge to public health. In the United States, it is estimated that antimicrobial resistant microorganisms cause over 2.8 million infections and 35,000 deaths annually with the most serious resistant pathogens responsible for over $4.6 billion in health care costs annually. But how do we know where resistant bacteria emerge and how do we stop antimicrobial resistance from spreading? The answer lies in AMR surveillance, a system designed to track resistant bacteria and guide smarter, safer antimicrobial use. Let's explore together how surveillance turns information into action, helping us understand and control AMR. AMR surveillance means systematically collecting and analyzing data on resistant bacteria and antimicrobial use. AMR surveillance programs help us see the big picture, identifying where resistance emerge, how it is spread, and which practices might be driving it. In the United States, laboratories routinely test bacteria from animals, food products, and farm environments. When resistance to certain antibiotics starts to increase, it serves as an early warning signal, allowing action before resistant variants of bacteria become widespread. And surveillance doesn't stop at the farm. By collecting samples from animals, food products, or even human infections, scientists can trace resistance patterns across the entire food chain. This helps identify how resistant genes move from farm animals to food and sometimes to people. This is why AMR monitoring must use a one health approach. This one health approach connects data across different sectors from animal, human, and environmental sources so researchers and policy makers can see how bacteria and resistance genes circulate between ecosystems and where to intervene so that target action will have the greatest impact. Tracking how and when antimicrobials are used in animals is just as important as detecting resistance. By analyzing trends in antimicrobial sales and prescriptions, surveillance programs identify sectors where stewardship can be improved. The data collected guide science-based policies. When authorities know which antibiotics are losing effectiveness, they can update guidelines, restrict certain uses, or promote alternatives to reduce selection pressure on bacteria. In the United States, the National Antimicrobial Resistance Monitoring System Program monitors AMR in animals, retail meats, and humans. Globally, the World Health Organization's Global Antimicrobial Resistance and Use Surveillance System Initiative uses shared standards to make data comparable across countries, helping track resistance trends and support coordinated responses worldwide. Effective surveillance depends on teamwork. Farmers, veterinarians, laboratories, and public health agencies each play a role. Farmers provide us access and information. Veterinarian and food specialist collect samples and laboratories and agencies analyze and share the data. This cooperation keeps the surveillance system strong and responsive because surveillance is not about blame, it's about unity. When all sectors share responsibilities and work together, we can protect the power of antibiotics for both animal and human health in the future. And surveillance data generated across different sectors aren't just numbers. They translate into action. On farms, results help identify where resistance problems are emerging and guide improvements in sanitation, waste management, and biosecurity practices to reduce the spread of resistant bacteria. In veterinary practice, surveillance helps identify which antibiotics remain effective for a specific herd or in a specific region. It also ensures proper dosing based on weight and label recommended duration of treatment while highlighting opportunities for preventive approach such as vaccination that can reduce the antimicrobial use. In laboratories and public health surveillance systems, it strengthens diagnostic capacity through standardized antimicrobial susceptibility testing panels that cover a broader range of antibiotics, introducing advanced and molecular rapid diagnostic tests when appropriate, improving sample logistics and data reporting, and workforce training for reliable results. In this way, monitoring becomes a powerful tool to mitigate AMR harder than just track it. Every country's surveillance effort contributes to a global understanding of By sharing information through networks like the World Health Organization, Food and Agriculture Organization of the United Nations, and World Organization for Animal Health, nations can respond faster to emerging threats and coordinate strategies across borders. AMR surveillance is our early warning system and our guide for a smarter action. By tracking resistance and antimicrobial use together, we can protect animal health, food safety, and preserve antibiotic effectiveness through one health, protecting animals, people, and the environment. Understanding and strengthening AMR surveillance is a shared responsibility across sectors because protecting one
