The ban ends — but the damage is already on the books
Starting August 24, 2026, the United States will resume live cattle imports from Mexico at the Douglas, Arizona, border crossing, which sits opposite Agua Prieta in Sonora state. The reopening closes a chapter that began in May 2025, when Washington shut the border over the New World screwworm fly — a flesh-eating parasite whose maggots burrow into the wounds of any warm-blooded animal, including wildlife, pets and, on occasion, humans.
The ban was not a minor inconvenience. Mexico's cattle export business generated $1.2 billion last year, and before the closure the country shipped roughly 1.2 million head of cattle annually to the United States, mainly from its northern states. When that pipeline closed, Mexican ranchers dumped animals onto the domestic market at prices nearly 40% below what U.S. buyers had been paying. Rancher Martín Alfonso Ibarra, 58, told the Associated Press the halt cut his income by 40%.
The pain was mutual. According to Juan Carlos Anaya, general director of agricultural consulting firm Grupo Consultor de Mercados Agrícolas, U.S. ranchers could not fill the supply gap, contributing to closures at some meat-processing plants and hurting feedlot operations. American consumers faced record-high beef prices and some cut back on meat purchases.
Sonora was chosen — then it got screwworm
The irony of the reopening site is hard to miss. Sonora was selected precisely because it appeared to be the last major cattle-producing state without a confirmed screwworm case. Then, on Wednesday, the first case in Sonora was reported in the community of Munihuasa, near the borders with Chihuahua and Sinaloa — two states where infections have already proliferated. The outbreak, first detected in November 2024, has since spread to 30 of Mexico's 32 states.
Mexico currently records 1,969 active screwworm cases — a figure authorities note represents less than half the infections reported a year ago, a decline they say demonstrates progress in containment. Eradication, however, remains a work in progress, and cases have already crossed into Texas and New Mexico.
Tight daily caps and new inspection rules
The U.S. Department of Agriculture is not opening the floodgates. In the first week, only 700 cattle per day will be permitted through Douglas; the limit rises to 900 in week two and will gradually climb to a ceiling of 1,300 head per day, according to veterinarian Arturo Ruiz, responsible for animal health for Sonora state. Every animal must carry a radio-frequency identification tag and pass screening by electronic readers and trained dogs, with USDA officials conducting final inspections before any cattle cross into Arizona.
Juan Carlos Ochoa, president of the Regional Livestock Union of Sonora, accepted the protocols but argued the caps are too tight. 'We are at a complicated moment when we need authorities to think less politically and more technically and reasonably,' he said, referencing the diplomatic friction that accompanied the original ban. If the Douglas crossing operates without incident, the USDA could authorize additional ports of entry.
CEO Times take
The numbers tell a straightforward story: a year of regulatory closure cost producers on both sides of the border hundreds of millions of dollars, pushed U.S. beef prices to record highs and forced Mexican ranchers to liquidate herds at a loss. Free enterprise does not thrive under prolonged administrative shutdowns, however justified the initial public-health rationale.
The phased reopening is the right direction, but the daily caps — 700 head on day one against a pre-ban annual run rate of roughly 3,300 head per day — signal that bureaucratic caution is still driving the timeline more than market need. Capital rewards clear rules and predictable supply chains. The sooner USDA expands the approved crossings and lifts the volume ceilings, the sooner ranchers, feedlots and American consumers get relief.
