asked the Minister of Agriculture, Fisheries and Food what was the incidence of brucellosis amongst cattle in England and Wales during 1961.
Information collected during a recent survey of this disease in dairy herds is being assembled and it is hoped that the results will be available in about three months.
In the meantime would my hon. Friend consider giving some information of the extent to which the germ brucellosis is found in T.T. milk, in view of the fact that the disease can be communicated to human beings, in which event it is rarely, if ever, correctly diagnosed by the medical profession, as was the unhappy experience of one of my unfortunate constituents?
Brucellosis is not present in heat-treated milk, which forms the greater part of the country's milk supply. I should not like to guess the result of the survey. It is likely to show great differences between different parts of the country, and even between different herds in the same district.
