§ Mr. Masonasked the Secretary of State for Employment (1) if the study being undertaken by the Health and Safety Executive's employment medical advisory service into the evidence relating to the health effects of chrysoidine in an occupational context is now complete; and if he will make a statement;
(2) if he will ask the Health and Safety Executive to carry out a study into the possible carcinogenicity of chrysoidine in animals and humans and to report on the matter;
(3) if he will ask the Health and Safety Executive's medical advisory service to conduct a full epidemiological study with a control population to establish whether there is a link between bladder cancer and chrysoidine dye.
§ Mr. WaddingtonThe Health and Safety Executive's employment medical advisory service has now collected and appraised the very limited published evidence relating to the health effects of chrysoidine. It has found that the evidence is inadequate for any firm conclusions on carcinogenicity or toxicity in humans to be drawn. The Health and Safety Executive is now seeking the view of the Department of Health and Social Security's committee on carcinogenicity of chemicals in food, consumer products and the environment about the potential human carcinogenicity of the dye. Further action will depend on the result of this consultation.
