§ Mr. Leachasked the Minister of Health what proof he possesses that the form of tuberculosis called bovine has ever been caused by drinking milk.
§ Mr. WillinkI am advised that human infection by the particular type of tubercle bacillus found in bovines can ordinarily be accounted for only by contact with this organism through eating meat or consuming milk or its derivatives. As the cooking of meat destroys the bacillus it must be concluded that tuberculosis of bovine origin is mainly attributable to milk. This is supported by the results of medical research showing incidence of bovine tuberculosis among persons drinking raw milk, but almost complete immunity from it among those drinking only pasteurised milk.
