A situation in which a huge number of carcasses would need to be disposed of is the introduction of a Foreign Animal Disease. Examples of Foreign Animal Diseases that are a great threat to the U.S. include Classical Swine Fever (hog cholera) and Foot and Mouth Disease. If a Foreign Animal Disease were to infect U.S. livestock, disease control programs would likely result in the need to destroy many animals humanely and to dispose of tens to hundreds of thousands of carcasses.
