No animal infected with brucellosis shall be sold, traded or otherwise disposed of except for immediate slaughter or as designated by the State Veterinarian and the person disposing of such infected animals shall see that they are promptly slaughtered and that a written report thereof is made to the State Veterinarian.

But the State Veterinarian may permit the sale of valuable purebred, registered animals that have reacted to an official brucellosis test or are suspected of such reaction, provided such animals go direct to infected herds that have been vaccinated with Brucella vaccine, as provided for in this article, and are held under quarantine in accordance with the law and regulations covering such quarantine.
