The United States has begun a phased reopening of its border to Mexican cattle imports after a ban lasting more than a year due to concerns about New World screwworm. Imports resumed through Douglas, Arizona, with two New Mexico ports potentially reopening within 60 days, while Texas ports will remain closed because of greater parasite activity. USDA officials say multiple safeguards and a science-based import protocol are designed to protect U.S. livestock, although some cattle groups and state officials remain concerned about the risk.
Mexico is strengthening containment efforts in Sonora and Chihuahua, where 185 screwworm cases have been confirmed, including 183 in Chihuahua. Authorities are increasing sterile-fly releases, inspections, livestock movement controls, and treatment programs. Meanwhile, USDA has identified 46 cases in Texas and New Mexico, with two active. Mexico recently opened a sterile-fly production facility in Chiapas, while a U.S. facility in Texas is expected in spring 2027.
