On June 3, 2026, a New World screwworm was detected in a calf in Texas. Kansas officials are collaborating with the USDA to prevent the pest, which threatens livestock but not food safety. Livestock owners are urged to monitor animals when traveling to affected areas, and early identification is crucial for treatment.

Mexico's SENASICA reported a new New World Screwworm case in Veracruz, prompting the U.S. to suspend livestock trade through southern ports to safeguard American agriculture. Despite plans for phased port reopenings, the detection raises concerns about pest control efforts in Mexico. USDA is stepping up measures to combat NWS and protect livestock.
