On Tuesday, September 2, 2014 at noon, about 45 liters of liquid contaminated with polio virus have been rejected from the production site to the GSK Rixensart local sewage treatment plant of Rosieres and subsequently in Lasne River.
The liquid was rejected due to human error during the process of vaccine production.
Belgian health authorities were directly involved at the request of the Minister of Public Health, all necessary measures as soon as they were notified of the situation. The Scientific Institute of Public Health and the Supreme Council of Health have conducted a risk analysis and confirm that there is no public health risk for the population.
The risk of developing polio for people who were exposed to contaminated water (swimmers and fishermen Lasne river, professionals working in the water treatment plant, …) is also very limited, given the high level of dilution and high level of public vaccination (vaccine against polio is compulsory in Belgium). People who have been in contact with the water and are worried should contact their family doctor to see whether revaccination is necessary.
Samples of mud and water from the treatment plant of Rosieres, Lasne and Dyle were taken Saturday, Sept. 6 to allow time to evaluate the persistence of the virus. The testing of these samples are negative: no presence of polio virus was detected.
He was asked the departments concerned to examine to examine the potential filing of a complaint to investigate the responsibility for this incident.
