§ Mr. Ron Lewis
asked the Minister of Labour what evidence he has about the liability to cancer of workers in the rubber industry as the result of certain chemicals used.
§ Mrs. Shirley Williams
As the House knows, investigations carried out by our Department have established that known carcinogenic substances ceased to be used in the rubber industry in this country in 1949. It is not known whether any of the substances at present used are carcinogenic, and a long-term survey is being carried out by our Department which will establish in time whether there is still a cancer hazard in the rubber industry.
