U.S. to reopen border to Mexican cattle imports after screwworm ban

The United States is set to reopen its border to Mexican cattle imports, beginning at Arizona's Douglas crossing, more than a year after a ban was imposed due to an outbreak of the flesh-eating screwworm parasite. The decision marks a significant step in restoring agricultural trade between the two countries. The ban had disrupted cattle exports from Mexico, impacting ranchers and the broader livestock industry. The reopening is expected to ease supply chain pressures and resume normal trade flows.
