The United States is set to resume Mexican livestock imports on Aug. 24 through the Douglas, Arizona, border crossing, which connects with Agua Prieta in Sonora, after a yearlong suspension linked to the New World screwworm parasite. The reopening will initially be limited to 700 cattle a day, rising to 900 in the second week and eventually 1,300, with additional ports potentially allowed if the process goes smoothly. Mexican cattle must carry radio-frequency identification tags and pass electronic-reader and trained-dog screening, with U.S. Department of Agriculture officials conducting inspections before entry. Mexico has 1,969 active screwworm cases across 30 of its 32 states, including a first case in Sonora, while authorities continue to battle infections in Texas and New Mexico. Mexico’s cattle-export industry, which generated $1.2 billion last year and previously sent about 1.2 million head annually to the United States, has suffered after ranchers were forced to sell domestically at prices nearly 40% below U.S. levels. The disruption has also intensified a U.S. cattle shortage, contributed to meat-processing cutbacks and helped push beef prices to records. The phased reopening has revived debate over animal-health safeguards, market access and protectionism, while Mexican producers argue that greater trade is needed to address supply shortages in both countries.
