The U.S. Department of Agriculture said May 11 that it is suspending imports of livestock through Mexico because of New World Screwworm threats.

Because the New World screwworm has been detected in southern Mexico and is spreading north, the U.S. is halting live cattle, horse and bison imports from Mexico, on the orders of U.S. Department of Agriculture Secretary Brooke Rollins.

The threat from the flesh-eating maggots, known as the New World Screwworm, has suspended live cattle imports through the southern border.
