US shuts southern border to livestock imports to stop spread of deadly flies

The Trump administration is temporarily banning imports of cattle, horses and bison through ports along the southern border because of the rapid northern spread of New World Screwworm (NWS) in Mexico.

U.S. Department of Agriculture (USDA) Secretary Brooke Rollins announced the suspension in an X post on Sunday.

"Due to the threat of New World Screwworm I am announcing the suspension of live cattle, horse, & bison imports through U.S. southern border ports of entry effective immediately," she wrote.
