Dried Milk (Tins) 12. Mr. Thornton-Kemsley asked the Minister of Food why his Department does not ask for the tins in which the national dried milk is issued to be returned, having regard to the present shortage of tinplate. Mr. Webb Returned tins are difficult to clean thoroughly, and to use them again for National Dried Milk would involve an obvious danger to infant health. Their use for other purposes is very limited, and would not justify the heavy costs involved in their collection and transport.
