For these purposes it may establish, maintain, enforce, and regulate such quarantine and other measures relating to the movement and care of animals and their products, the disinfection of suspected localities and articles and the destruction of animals, as it deems necessary, and may adopt from time to time all such regulations as are necessary and proper for carrying out the purposes of this chapter and Chapter 73 of this title. In the case of a contagious disease, the Department or its authorized agents may put under quarantine the entire herd containing the suspected or diseased animal or animals.
