In reply to the first part of the Question, no evidence is available. In regard to the second part, I am advised that it would be unusual in medical practice not to make such inquiries in cases of tuberculosis among young children, but that the point becomes less relevant after childhood.
asked the Minister of Health whether he is aware that the infant mortality from certain forms of tuberculosis is higher in Greater London and the county boroughs, where a great part of the milk consumed is pasteurised, than in rural districts where most of the milk consumed is unpasteurised; and is he satisfied that pasteurisation is doing the work claimed for it in the circulars issued by his Department?
If as I assume from my hon. Friend's reference to pasteurisation the first part of the Question relates to non-pulmonary tuberculosis, the answer is, "No, Sir"; the increase in child mortality from non-pulmonary tuberculosis appears to be greater in country than in town. The information available therefore casts no doubt on the efficacy of pasteurisation.
