asked the Secretary of State for Scotland if he is satisfied that existing pasteurisation plants for milk in Scotland have proved satisfactory; how many such plants there are; and what percentage of milk sold to the public is tubercular-tested, pasteurised and natural.
There are 100 pasteurising or heat-treatment plants in Scotland. The milk from these is tested fortnightly and the results generally are satisfactory. Of the milk sold off Scottish farms, some 70 per cent. is from tuberculin-tested herds. Milk as sold to the public comprises approximately 10 per cent. sold as "T.T.," 70 per cent. pasteurised or heat-treated, and 20 per cent. sold as ordinary milk, non-pasteurised.
