The United States Department of Agriculture (USDA) has published a final rule for traceability of animals moved interstate. Effective March 11, 2013, unless explicitly exempt, animals moved interstate must be accompanied by an interstate certificate of veterinary inspection or comparable documentation. The rule applies to livestock (all farm-raised animals), i.e., cattle and bison, horses and other equine species, poultry, sheep and goats, swine, and captive cervids.
