Protecting Against Mad Cow Disease

A national system to identify livestock is in the works. And agriculture officials say North Carolina is ahead of everyone else.

That's because North Carolina already has a system to identify groups of animals and some individual ones. The initiative by the U.S. Department of Agriculture would require each state to create its own identification system to be integrated into a nationwide one.

Officials says they saw a need for a standardized system during last year's Mad Cow disease scare.
