Why environmental surveillance is gaining ground in poultry AMR
CURRENT BRIEF VERSION: A new JAVMA review is arguing that the U.S. poultry sector needs to pay much closer attention to the farm environment when tracking antimicrobial resistance, not just birds at slaughter or meat at retail. In the paper, published online September 17, 2025, Auburn University researchers Pankaj Prakash Gaonkar and Laura Huber say current surveillance frameworks leave a major blind spot because soil, water, air, litter, and other farm-associated reservoirs can help resistant organisms and resistance genes persist and spread even when antimicrobial use declines. They frame that gap as part of a broader One Health problem affecting animal, human, and environmental health, with AMR already linked to an estimated 700,000 human deaths globally each year and projections reaching 10 million annually by 2050 if no effective action is taken. Their point lands in the context of existing federal monitoring programs, including NARMS and USDA surveillance efforts, which largely emphasize slaughter, retail, and selected on-farm sampling rather than routine, integrated environmental monitoring.

Why it matters: For veterinarians working in poultry health, stewardship conversations can't stop at prescribing decisions. The review frames antimicrobial resistance as a One Health systems problem, where biosecurity, litter management, water quality, farm traffic, and other environmental factors may influence how resistance is maintained across the production chain. It also comes as poultry remains one of the fastest-growing protein sectors, increasing the stakes for surveillance that can catch persistence and spread earlier in production. That has practical implications for flock health programs, diagnostic interpretation, and producer guidance, especially as the industry continues to document stewardship efforts while researchers still detect resistance in production environments.

What to watch: Expect more discussion around whether U.S. AMR monitoring should expand to standardized environmental sampling on poultry farms, and how that could be built into existing USDA, academic, and industry surveillance efforts. (usda.gov)
