HC Deb 28 July 1952 vol 504 c1083
32. Mr. Russell

asked the Minister of Food what proportion of milk produced is pasteurised; how much of this is mixed with non-pasteurised milk before sale; and what improvements he anticipates in the proportion of pasteurised milk in the future.

Dr. Hill

A total of 82 per cent. of all milk sold in the liquid market in England and Wales and 73 per cent. in Scotland is already pasteurised or sterilised, and these percentages will gradually be improved. None of this milk is mixed with other milks before sale.
