US Halts Mexican Cattle Imports Over Screwworm Spread

The United States has suspended imports of live cattle, horses, and bison through ports along the southern border due to the rapid spread of the New World screwworm parasite, which was previously eradicated from the U.S. in 1966. The measure, announced by U.S. Agriculture Secretary Brooke Rollins, is effective immediately and subject to monthly review as containment efforts in Mexico progress. The parasite, deadly to animals and dangerous to humans, has been detected as far north as Oaxaca and Veracruz, about 700 miles from the U.S. border. Mexico’s Agriculture Secretary Julio Berdegué has disagreed with the suspension but expressed hope for a swift resolution. Livestock already in holding facilities will continue to be processed, inspected, and treated. U.S. and Mexican authorities are collaborating to contain the spread following confirmed cases in both humans and animals in Mexico.
