The USDA’s Animal and Plant Health Inspection Service issued a proposed rule on Aug. 9 to establish general regulations for improving the traceability of U.S. livestock moving interstate when animal disease events take place.

"Through the past two years, I have listened carefully to stakeholders throughout the country about how to reach effective animal disease traceability in a transparent manner without additional burden," said Agriculture Secretary Tom Vilsack. "We are proposing a flexible approach in which states and tribes can develop systems for tracing animals that work best for them and for producers in their jurisdiction. This approach offers great flexibility at the state and local level and addresses gaps in our disease response efforts."

The proposed rule would apply to horses and other equines, cattle and bison, sheep and goats, swine, captive cervids (e.g., deer and elk), and poultry.

Under the proposed rule, unless specifically exempted, livestock moved interstate would have to be officially identified and accompanied by an interstate certificate of veterinary inspection or other documentation, such as owner-shipper statements or brand certificates. The proposed rule encourages the use of low-cost technology and specifies approved forms of official identification for each species, such as metal eartags for cattle. However, recognizing the importance and prevalence of other identifications in certain regions, shipping and receiving states or tribes are permitted to agree upon alternative forms of identification such as brands or tattoos
