Economic Relief as U.S. Reopens Mexican Cattle Imports After Screwworm Ban Ends
The U.S. will reopen Mexican cattle imports after a year-long ban, easing record beef prices while reigniting debate over livestock disease risks.
The U.S. Department of Agriculture (USDA) announced on July 24 that it will lift its year-long ban on Mexican cattle imports, allowing shipments to resume through Douglas, Arizona, within 30 days. The decision follows agreements with Mexican authorities on measures to control the spread of the New World screwworm, a flesh-eating parasite that threatens livestock. The move matters because the import suspension contributed to record-high U.S. beef prices, tightened cattle supplies, and increased pressure on the Trump administration to lower food costs for consumers while stabilizing the livestock industry.
The reopening will occur gradually, with Douglas, Arizona, serving as the first entry point, followed later by two additional ports in New Mexico. According to the USDA, every phase of the reopening will depend on Mexico's continued compliance with surveillance and pest-control protocols designed to limit the spread of the New World screwworm. Federal officials argue that current conditions make it safe to begin restoring cross-border cattle trade, while maintaining strict monitoring procedures to reduce biosecurity risks.
Industry Welcomes Supply Boost but Warns Disease Risks Remain
The prolonged border closure significantly disrupted the U.S. cattle market, helping push domestic cattle inventories to their lowest level in 75 years. Combined with years of drought that forced ranchers to reduce herd sizes, the import ban drove cattle costs sharply higher and contributed to record retail beef prices. The tighter supply also placed financial pressure on meat processors, with companies including Tyson Foods and JBS announcing processing plant closures this year as margins tightened across the industry.
Mexican President Claudia Sheinbaum confirmed that her government has instructed officials to accelerate preparations so livestock exports can restart during the final weeks of August. Meanwhile, Texas Agriculture Commissioner Sid Miller welcomed the decision, arguing that restoring trade is positive for ranchers and consumers alike, but criticized the lengthy delay, saying producers have already suffered economic losses, supply chain disruptions, and uncertainty that could leave lasting effects across the U.S. cattle sector.
Not everyone supports the reopening. R-CALF USA CEO Bill Bullard warned that renewed imports could increase the risk of additional screwworm infestations, arguing that reopening the border may encourage cattle movement from southern Mexico, where the parasite remains endemic. By contrast, the Meat Institute and the Texas Cattle Feeders Association said scientific evidence supports a carefully managed reopening, emphasizing that enhanced inspection protocols and phased border operations can protect U.S. livestock while restoring an essential supply of feeder cattle.
The decision reflects the difficult balance facing policymakers between protecting animal health and supporting agricultural markets. Arizona and New Mexico were selected because they are farther from current screwworm outbreaks than Texas, reducing the immediate biological risk while allowing beef processors access to additional cattle supplies. For U.S. ranchers, meatpackers, investors, and consumers, the reopening represents one of the most significant livestock trade developments of the year, with direct implications for beef prices, supply chains, farm profitability, and agricultural trade across North America.
