Mad cow, eh

In what could potentially become an economic disaster of historical magnitude, mad cow disease has been diagnosed in North America for the first time in ten years. Despite herculean efforts to prevent the spread of the disease to the massive herds of Canadian and American cattle, it's here. The case was just one cow out in Alberta, and it's not known whether the cow was imported or not. The rest of its herd has been impounded and will be slaughtered and examined. If more cases of the disease start springing up, this could wreak havoc on the Canadian and potentially the American economy.
