Surface trade between the United States’ top North American trading partners, Mexico and Canada, fell at an all-time high rate in February.
That trade by truck, train or pipeline fell 30.9 percent in February according to the Bureau of Transportation Statistics, an arm of the U.S. Department of Transportation.
That year-to-year drop was the largest single month drop since the bureau began tracking such trade.
February was the fourth month in a row when trade between the U.S. and Mexico and Canada fell more than 13 percent.
The dollar volume of trade was $47.9 billion, the BTS said.
That drop came before the late April revelation of a swine flu outbreak in Mexico, a development that has strangled trade between the two countries in the last week.
