MEXICO CITY, June 9 (Reuters) – Mexico will stop most imports ​of live animals from ‌the U.S. after cases of the flesh-eating screwworm pest were confirmed in Texas and ‌New ​Mexico, Mexico’s agriculture ⁠ministry said on ⁠Tuesday.

The suspension applied to cattle, horses, pigs, sheep, goats and several other species ​of animals, the ministry said, adding that ⁠the decision was ⁠taken in coordination ​with the United States Department ​of Agriculture (USDA).

Mexico, which has registered ‌more than 28,200 cases of screwworm since November 2024, said it aimed ⁠to protect its cattle herd in the northern states of Baja ⁠California, ‌Baja California Sur, ⁠Chihuahua and Sinaloa, where ​there ‌are currently no ​confirmed cases ⁠of screwworm.

The U.S. has confirmed five cases of screwworm since June 3.
