These measures fall into three groups. in which the presence of bovine tuberculosis is established are placed under Under these regulations it is comprehensive quarantine regulations. provided, among other things, that milk from tuberculous animals may only Tuberculous animals for this purpose are be sold if boiled or pasteurised. animals in herds in which the presence of tuberculosis has been established, except in herds which have been tested with tuberculin and in which measures to isolate reacting cattle have been taken, in which case reacting animals alone are considered tuberculous. The presence of tuberculosis in a herd is established through the reports of farmers themselves and of veterinary surgeons, whether in public employment or in private practice, all of whom are bound to notify the appropriate authorities of any instance of tuberculosis which they may discover, through the reports of inspecting a result of tests of milk for authorities at slaughterhouses, and as tuberculosis undertaken by public health authorities.
31. Secondly, there is a scheme in existence for the examination of herds with tuberculin at the public expense. Such examinations are undertaken in suitable cases on the application of the owner, so far as funds voted by the Storting permit. Animals found to react to the tuberculin test and non-reacting animals with clinical symptoms of tuberculosis must be marked, and, unless the veterinary surgeon in charge decides otherwise, must be slaughtered within three weeks of the examination. Partial compensation is paid for animals slaughtered. Owners must undertake to carry out the instructions of the veterinary authorities. Failure to do so makes the owner liable to refund any money expended by the government under the scheme on his behalf, together with interest thereon.
