On March 11, 2013, the United States Department of Agriculture (USDA) initiated the Animal Disease Traceabil­ity Program (ADTP) to track interstate livestock movement. According to the USDA, “Animal disease traceability, or knowing where diseased or at-risk animals are, where they have been and when, is very important to ensur­ing a rapid response when animal disease events take place. This will reduce the number of animal owners impacted by an animal disease event and reduce the economic strain on owners and affected communities.” The new rule replaces the previous unpopular version of the National Animal Identification System (NAIS) and pertains to all livestock, including cattle, horses, sheep and goats.
