Mexico Boosts Controls After New Screwworm Case Near US Border
Mexico has activated emergency controls following the detection of a new case of New World screwworm in cattle. The case, identified in the northern border state of Nuevo Leon, represents the closest instance to the U.S. border since the outbreak began last year, prompting concerns and renewed efforts to contain the parasite.
Screwworm Outbreak and Response
The affected animal was discovered in Sabinas Hidalgo and originated from the Gulf state of Veracruz. According to Mexico's National Health for Food Safety and Food Quality Service, the last reported case was on July 9 in Veracruz, which led to the U.S. suspending imports of live Mexican cattle. The screwworm, a larva of the Cochliomyia hominivorax fly, poses a threat to warm-blooded animals, including humans. Over 500 active cases in cattle have been reported across southern Mexican states.
Economic Impact and Trade Concerns
The import ban on cattle has created challenges for the Mexican government, already dealing with the fallout from previous U.S. tariff threats. Both the government and ranchers are actively working to have the ban lifted. If the ban remains in effect throughout the year, Mexico's ranching federation estimates potential losses of up to $400 million.
Official Statements and Cross-Border Measures
Mexico's Agriculture Secretary Julio Berdegué stated on X that Mexico is "controlling the isolated case of screwworm in Nuevo Leon,” under measures to combat the pest, agreed upon with the U.S. in August. However, U.S. Agriculture Secretary Brooke Rollins emphasized that Washington would take “decisive measures to protect our borders, even in the absence of cooperation” and confirmed that the suspension of imports on Mexican cattle, bison, and horses would continue. She stated that the U.S. “will not rely on Mexico to defend our industry, our food supply or our way of life.”
