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.

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.
