In the Poyang Lake basin of China, where some 45 million people draw their drinking water, a new study reveals that not all water sources carry equal burdens of antibiotic resistance — rivers, shaped by the pressures of livestock farming, sewage, and aquaculture, harbor significantly greater contamination than reservoirs. The distinction is not merely hydrological but deeply human: the type of water source determines how resistance genes enter, persist, and move through aquatic life. Science is now asking water managers to see these differences not as footnotes but as the foundation of any ser
River water sources pose higher antibiotic resistance risks than reservoirs
Potential public health risk to approximately 45 million people relying on Poyang Lake basin drinking water sources due to antibiotic resistance contamination.
