The Bush administration on Friday urged a federal appeals court to stop meatpackers from testing all their animals for mad cow disease, but a skeptical judge questioned whether the government has that authority.

The government seeks to reverse a lower court ruling that allowed Arkansas City, Kan.-based Creekstone Farms Premium Beef to conduct more comprehensive testing to satisfy demand from overseas customers in Japan and elsewhere.

Less than 1 percent of slaughtered cows are currently tested for the disease under Agriculture Department guidelines. The agency argues that more widespread testing does not guarantee food safety and could result in a false positive that scares consumers.
