HC Deb 30 April 1965 vol 711 c94W
Dr. Summerskill

asked the Minister of Agriculture, Fisheries and Food what evidence he has as to the extent to which hormones used in the intensive rearing of chickens for human consumption cause cancer among chickens.

Mr. Peart

I am not aware of any use of hormones in the production of broilers or of any evidence that cancer in chickens is caused by the use of hormones.
