GSK says risk is low from vaccine-contaminated water released into Belgian river

GlaxoSmithKline ($GSK) has been working with Belgian officials after "human error" resulted in 45 liters of cleaning liquid contaminated with poliovirus getting dumped into a city sewer system and subsequently into the Lasne River. GSK in an emailed statement acknowledged the incident at the GSK Rixensart site in early September. It said the risk of anyone getting polio from the episode is low. Samples taken from the treatment plant in Rosières from the Lasne and the Dyle rivers four days after the incident "were negative: 'no presence of poliovirus was detected.'" It said its focus now is to "ensure that all necessary measures are put in place to prevent any similar incident occurring again." Story
