USDA Cracks Open the Cattle Border: Douglas, Ariz., Port Set to Reopen Aug. 24
Phased restart of Mexican cattle imports leans on Sonora and Chihuahua’s animal-health track record — and lands as the U.S. battles its own screwworm outbreak in Texas.
Analysis · July 24, 2026
After more than a year of shuttered southern ports, USDA on July 24 announced a phased reopening of the U.S./Mexico border to livestock trade, starting with the Douglas, Ariz., port of entry on Aug. 24 — a move contingent on Mexico holding up its end of the binational Joint Action Plan against New World screwworm (NWS).
Every animal crossing at Douglas will undergo a full USDA inspection to confirm it is free of any sign of NWS. As Douglas reopens, USDA will simultaneously begin the operational groundwork to restart the Santa Teresa and Columbus, N.M., ports for live cattle, bison and horses — but only after the department evaluates how the initial reopening performs and whether the risk picture holds.
“Protecting the United States from NWS and pushing this pest out of Mexico and back to the Darien Gap is a top priority at USDA,” said USD Secretary Brooke Rollins, who called the year-long closure “a tough but necessary action” and said it is now safe to resume “the hundreds year old movement of cattle” through Douglas.
The reopening question has fundamentally changed: it is no longer whether USDA can keep screwworm out of the country, but how the department manages a pest that is now established on both sides of the border.
Why Sonora and Chihuahua go first
USDA identifies Sonora and Chihuahua as the lowest-risk Mexican states for NWS, citing decades of well-established inspection infrastructure built on successful animal disease control campaigns, plus geographic distance from southern Mexico, where cases are concentrated. The closest active case to the Douglas port is roughly 325 miles away, detected July 22.
The department was blunt about the rest of the country: “the rest of Mexico has not been able to stop the spread of the screwworm or stop legal and illegal movement.” That signals the phased approach will stay narrow, and USDA says openings may be paused if post-opening audits point to increased risk in either state. The timeline “will remain flexible.”
Market impact: psychology vs. fundamentals
Before the crisis, Mexico shipped 1.1 million to 1.2 million feeder cattle north annually — roughly 3% to 3.5% of U.S. feeder supply. The on-again, off-again closures that began in November 2024 cut 2025 imports to an estimated 230,000 head, and the pipeline has been essentially dry since July 2025. Industry estimates suggest on the order of 120,000 head per month have been backing up in Mexico awaiting a reopening.
Futures may react more violently than the fundamentals justify. When Mexico’s president merely floated reopening talks last October, feeder cattle futures locked limit down. But with the U.S. calf crop the smallest since 1941, cattle prices at or near records and little heifer retention underway, most economists — including Oklahoma State’s Derrell Peel and Texas A&M’s David Anderson — argue a phased restart is “not that big a deal” for supply. Volumes will ramp slowly, and analysts do not expect meaningful restoration before 2027.

The awkward backdrop: NWS is already in Texas
The reopening decision comes with an uncomfortable asterisk. In June, APHIS confirmed the first domestic U.S. screwworm case in decades in a calf near La Pryor, Texas, and the case count in Texas and New Mexico has since climbed past 30. USDA is thus reopening the border while running an active eradication campaign at home — sterile-fly dispersal, movement controls and surveillance. Critics will ask why import risk is acceptable now; supporters counter that fully inspected Sonora-Chihuahua cattle were never the pathway of concern, and that the closure’s cost to feedlots and packers grows weekly.
Bottom line
The Aug. 24 Douglas opening is more symbol than supply: a few weeks of inspected Sonoran cattle will not dent record-tight U.S. feeder numbers, but it is the first concrete step toward normalizing a trade frozen for a year. Watch three things: the futures reaction, whether Santa Teresa and Columbus follow this fall, and the Texas case count — a northward jump in Mexico or a widening U.S. outbreak puts the plan back on pause. For cow-calf producers, the record-price story stays intact; for feedlots, relief arrives in increments, not a flood.
