Untreated Raw Milk 31 and 32. Mr. H. Hynd asked the Minister of Agriculture, Fisheries and Food (1) what steps he is taking to limit, and prohibit, the sale of untreated raw milk, except for manufacturing processes;(2) what is the percentage of untreated raw milk now being sold. Mr. Vane Rather less than 6 per cent. of the milk sold by retail in England and Wales is raw milk. It would not be practicable to require all milk to be heat-treated before sale to the public.
