There’s a new research report in Environmental Health Perspectives, entitled “Oseltamivir Carboxylate – the Active Metabolite of Oseltamivir Phosphate (Tamiflu), Detected in Sewage Discharge and River Water in Japan.”

One problem pointed out in the paper is that the metabolite’s presence in warm sewage discharge waters, where birds ten to flock, could help foster development of tamiflu resistant strains of H1N1 virus (swine flu).  The potential solution?  The paper’s results demonstrate that advanced sewage treatment with ozonation reduces significantly the concentration of this metabolite in wastewater discharges, as opposed to conventional sewage treatment, which does not do nearly as good a job.
