HC Deb 18 March 1957 vol 567 cc4-5W
67. Dr. Bennett

asked the Minister of Health what evidence he has of the transmission of poliomyelitis in untreated sewage or water contaminated with it; and if he will make a statement.

Mr. Vosper

I am advised that untreated sewage contains large amounts of poliomyelitis virus when infection occurs in a community, and that polluted water is assumed to be a constant risk. But there is no definite evidence in this country of the transmission of poliomyelitis from these sources.
