Bush administration fights to prevent testing for mad cow diease

The Bush administration said Tuesday it will fight to keep meatpackers from testing all their animals for mad cow disease.

The Agriculture Department tests fewer than 1 percent of slaughtered cows for the disease, which can be fatal to humans who eat tainted beef. A beef producer in the western state of Kansas, Creekstone Farms Premium Beef, wants to test all of its cows.

Larger meat companies feared that move because, if Creekstone should test its meat and advertised it as safe, they might have to perform the expensive tests on their larger herds as well.
