Sen. Arlen Specter, R-Pa., and Sen. Patrick Leahy, D-Vt., have introduced legislation to create a mandatory national-animal-ID program. The National Farm Animal Identification and Records Act requires the USDA to track the movement of any animal within 48 hours. And, it requires that a national-tracking system for all U.S. livestock be up and running within 90 days of the bill becoming law.

That is significantly faster than the proposed U.S. National Animal ID Plan, which phases-in a voluntary system that becomes fully operational in 2006. For more information, go to
