HC Deb 31 July 1918 vol 109 cc419-20
38. Mr. WRIGHT

asked whether the Board has any information as to the percentage of the cows in the dairy herds of Great Britain that do not react to the tuberculin test; and whether it is more important that the animal should not react to the test or that her milk should be free from tubercle?

Sir R. WINFREY

The Board have no information as to the number of cows in dairy herds which react to the tuberculin test. It seems more important that milk should be free from tubercle bacilli than that the cows producing it should not react to the tuberculin test, though I am advised that the best way of securing tubercle free milk is to keep a herd of non-reacters.
