Washington -- The U.S. national system to track livestock from birth to slaughter will take effect in 2007 and is expected to achieve full voluntary participation from livestock producers by 2009, says Secretary of Agriculture Mike Johanns.
The system will allow the U.S. Department of Agriculture (USDA) to identify all herd-mates of a diseased animal within 48 hours of the discovery of a serious livestock illness, he said during an April 6 press briefing.
"This represents one of the largest systemic changes ever faced by the
livestock industry," the secretary said.
The "massive" project that will account for some 100 million head of cattle in the United States is being implemented on a "very aggressive schedule," he said.
USDA began to implement the first stages of the system -- called the National Animal Identification System (NAIS) -- in 2004, shortly after the first case of bovine spongiform encephalopathy (BSE), or mad cow disease, was discovered in one cow in December 2003.
