When the Department determines that any animal is affected with, or has been exposed to, any contagious or infectious disease, it may agree with the owner upon the value of the animal or of any property that it may be found necessary to destroy, and in case such an agreement cannot be made, the animals or property shall be appraised by three competent and disinterested appraisers, one to be selected by the Department, one by the claimant, and one by the two appraisers thus selected. The appraisers shall subscribe to an oath in writing to fairly value such animals or property in accordance with the requirements of this Act, which oath, together with the valuation fixed by the appraisers, shall be filed with the Department and preserved by it.
Upon the appraisement being made, the owner or the Department shall immediately destroy the animals in a humane manner, dispose of the carcasses thereof, and disinfect, change or destroy the premises occupied by the animals, in accordance with rules prescribed by the Department governing such destruction and disinfection, and upon his failure so to do or to cooperate with the Department, the Department shall cause such animals or property to be destroyed and disposed of, and thereupon the owner shall forfeit all right to receive any compensation for the destruction of the animals or property.
