Rollins to Visit Arizona as USDA Mulls Port Reopenings

Why It Matters

Reopening the ports could revive cross‑border cattle trade and stimulate the Southwest economy, but doing so prematurely could introduce the New World screwworm, threatening U.S. livestock health and market stability.

Key Takeaways

• Rollins to inspect Douglas port as USDA reviews cattle import reopening
• Border towns cite economic loss from year‑long livestock trade suspension
• USDA cites 1,295 active NWS cases in Mexico, especially near Texas
• Officials propose using two Arizona ports to limit cattle concentration
• Sterile‑fly releases have not curbed NWS spread, prompting alternative controls

Pulse Analysis

The United States and Mexico share a $10 billion‑plus annual cattle market, with Arizona’s Douglas and Nogales crossings historically serving as critical conduits for feeder‑cattle shipments. When the USDA halted livestock movement last year amid pest concerns, border communities like Douglas and Nogales saw hotels, restaurants, and service businesses lose revenue that typically flows from multi‑day cattle drives and quarantine stays. Local leaders now argue that the economic shock is unnecessary, pointing to robust traceability systems and existing quarantine protocols that have successfully prevented pest incursions despite the trade pause.

At the heart of USDA’s hesitancy is the New World screwworm, a parasitic fly that can devastate livestock if it establishes in the United States. As of mid‑April, Mexican authorities reported 1,295 active cases, with hotspots in Nuevo León and Tamaulipas—states that border Texas. The parasite is now within roughly 200 miles of the Texas‑Mexico border, prompting Texas Ag Commissioner Sid Miller to warn of a possible summer arrival. The agency’s current mitigation strategy relies on releasing 100 million sterile flies weekly, a tactic that producers say has stalled, prompting calls for supplemental insecticide‑baited traps.

Looking ahead, USDA officials are weighing a regionalized reopening that would split cattle between Douglas and Nogales, reducing the density of animals at any single point and potentially limiting pest exposure. Such a dual‑port approach could balance economic recovery with bio‑security safeguards, but it hinges on clear data about screwworm movement and the efficacy of new control measures. Stakeholders will be watching Rollins’ upcoming site visit closely, as her assessment could set the timetable for reactivating a trade corridor that supports both border economies and national livestock health.
