Minnesota's pork producers, already stung by tariff hikes from China, are now being whacked with a round of duties from Mexico.
It's all part of a growing trade war, with longtime U.S. allies counterpunching after President Donald Trump imposed a round of tariffs on metal imports.
Minnesota is the nation's third-largest hog-producing state, and Mexico is the largest market for U.S. pork exports by volume.
Hog growers in the state are part of the "collateral damage," said Dave Frederickson, commissioner of the state Department of Agriculture. Hog prices have fallen since winter, and prolonged trade troubles could deeply damage the state's hog growers.
"Some will go out of business, and there's no doubt that you can blame trade for part of that," Frederickson said.
Mexico said Tuesday it would impose tariffs of 20 percent on U.S. pork, apples and potatoes, as well as duties of 25 percent on certain U.S. cheese products and Tennessee whiskey — covering about $3 billion of goods altogether.
Minnesota ships about $54 million worth of pork to Mexico annually. The state also exports a considerably smaller of amount of cheese and potatoes to Mexico.
The Trump administration last week hit Mexico and Canada with tariffs of 25 percent and 10 percent respectively on steel and aluminum, citing national security concerns.
