US To Resume Mexican Cattle Imports After Yearlong Screwworm Ban

The United States said on Friday it will end a ban on imports of Mexican cattle implemented more than a year ago to combat the New World screwworm (NWS), a flesh-eating livestock pest that has already made it into Texas and New Mexico.

In its announcement, the U.S. Department of Agriculture (USDA) said it would coordinate a phased reopening of southern cattle ports beginning Aug. 24.

USDA officials said the United States will first start taking Mexican cattle again at Douglas, Arizona, with two more ports in New Mexico to follow.

The reopening will be staged and depends on Mexico sticking to its New World screwworm control plan. Officials called the move safe to begin now.

Ports in Arizona and New Mexico sit farther from the heaviest infestations in Mexico, livestock traders noted, which lowers the immediate risk compared with Texas crossings.

"Every animal entering the United States through these ports will undergo a full USDA inspection to ensure it is free of any signs of New World screwworm (NWS)," the USDA said.

The United States suspended imports of live Mexican cattle and related livestock on May 11, 2025, as part of efforts to curb the spread of the parasite.
