§ 5. Mr. Farrasked the Minister of Health, as representing the Minister for Science, what investigations he has made into the possibility of certain toxic sprays used in agriculture causing cancer; and with what result.
§ Mr. Walker-SmithIn the investigations on the toxic effects of chemical sprays used in agriculture which are being sponsored by the manufacturers of the products and the Medical Research Council and other organisations, consideration is always given to the possibility that these substances may cause cancer. A few substances have been condemned in the United States, but the great majority proposed for use show no evidence of such properties.
§ Mr. FarrIs the Minister aware that scientific research abroad has shown that certain of these weed killers can cause thyroid cancer in rats? In view of that information, will he take steps to urge his right hon. Friend the Minister of Agriculture to appoint a commission to inquire into this and other aspects of toxic sprays.
§ Mr. Walker-SmithI am sure that my right hon. Friend will take note of what my hon. Friend has suggested, but I would like to make it clear that no toxic sprays have been condemned in this country as carcinogenic, and those identified as such in the United States have not found their way on to the British market.
