MEXICO CITY (AP) — Mexico activated emergency controls Monday after detecting a new case of New World screwworm in cattle in the northern border state of Nuevo Leon state, the closest case to the U.S. border since the outbreak began last year.

The animal, found in the town of Sabinas Hidalgo, came from the Gulf state of Veracruz, Mexico’s National Health for Food Safety and Food Quality Service said. The last case was reported July 9 in Veracruz, prompting Washington to suspend imports of live Mexican cattle.

The parasite, a larva of the Cochliomyia hominivorax fly, attacks warm-blooded animals, including humans. Mexico has reported more than 500 active cases in cattle across southern states.

The block on cattle imports has spelled trouble for Mexico’s government, which has already been busy trying to offset the brunt of U.S. President Donald Trump’s tariff threats this year.

The government and ranchers have sought to get the ban lifted. If it stays in place through the year, Mexico’s ranching federation estimates losses up to $400 million.

Mexico’s Agriculture Secretary Julio Berdegué said in a post on X that Mexico is “controlling the isolated case of screwworm in Nuevo Leon,” under measures to fight the pest agreed with the U.S. in August.

U.S. Agriculture Secretary Brooke Rollins said Washington will take “decisive measures to protect our borders, even in the absence of cooperation” and said imports on Mexican cattle, bison and horses will remain suspended.

“We will not rely on Mexico to defend our industry, our food supply or our way of life,” she said.
