ScienceDaily (Nov. 14, 2011) — A new University of Minnesota study reveals that treated municipal wastewater -- even wastewater treated by the highest-quality treatment technology -- can result in significant quantities of antibiotic-resistant bacteria, often referred to as "superbacteria," in surface waters.
The study also suggests that standard wastewater treatment technologies probably release far greater quantities of antibiotic-resistant genes used by bacteria, but this likely goes unnoticed because background levels of bacteria are normally much higher than in the water studied in this research.
