Launch Trade War

A U.S. federal judge struck another blow to Canada's cattle industry Monday -- the day the American border was supposed to re-open to imports of live Canadian cattle under 30 months of age.

The American Meat Institute (AMI) had asked for a preliminary injunction against the U.S. Department of Agriculture's original ban on the imports of Canadian beef or cattle, in place since May, 2003. That's when Canada discovered its first case of bovine spongiform encephalopathy (BSE), or mad cow disease.

But the U.S. meat industry group's request was denied, announced the clerk's office at the U.S. District Court in Washington on Monday.
