What happens to antibiotics after they've done their job on the farm?
Some can remain in livestock wastewater, along with genetic material that allows bacteria to resist antibiotics. If left untreated, those contaminants can move beyond the farm and contribute to the spread of antimicrobial resistance.
Dr. Kiranmayi Mangalgiri and an interdisciplinary research team, including Dr. Mark Krzmarzick, are studying the effectiveness of ozone nanobubbles in addressing the problem.
The goal is to build the scientific knowledge needed to make wastewater treatment more predictable and effective for livestock producers.
“Everyone benefits from cleaner water,” Mangalgiri said. “If we can remove these contaminants before they leave the farm, we're helping protect agriculture, communities, and public health.”
