US-Mexico Border Reopening for Cattle Imports: A Cautious Step Amid Screwworm Threat
After a dangerous screwworm outbreak halted cattle imports from Mexico, the US plans a cautious border reopening—highlighting the need for vigilance against agricultural threats that risk American livestock and sovereignty.

In a development that underscores both the risks and responsibilities inherent in cross-border agriculture trade, U.S. and Mexican officials announced plans to gradually reopen the southern border to cattle imports starting July 7. This comes on the heels of a suspension imposed in May amid fears over the northward spread of the devastating screwworm pest.
The screwworm, Cochliomyia hominivorax, is no trivial nuisance—it poses a lethal threat by invading living tissues of warm-blooded animals, causing severe lesions and even death. The stakes are high for America’s cattle industry and rural communities whose livelihoods depend on protecting livestock health and biosecurity.
U.S. Agriculture Secretary Brooke Rollins emphasized progress made with an aggressive sterile fly release program dispersing over 100 million flies weekly, noting no evidence of northward spread for eight weeks—a critical benchmark. However, this cautious optimism follows earlier false starts: after an initial ban in November was lifted in February due to improved screening protocols, another halt came swiftly in May after what was described as “unacceptable northward advancement” threatened vulnerable American herds.
This yo-yo approach exposes the reality that porous borders complicate efforts to safeguard U.S. agricultural sovereignty. While cooperation between USDA and Mexican authorities—highlighted by virtual meetings between Secretary Rollins and Mexico’s Julio Berdegué—is commendable, it also demands rigorous enforcement beyond diplomatic plaudits.
Protecting America’s Agricultural Borders Means No Shortcuts
America First means putting our farmers and ranchers first—not gambling their safety on incomplete assurances. The screwworm threat should remind us why strong border security measures apply not only to immigration but also to invasive pests that can decimate industries vital to national prosperity.
Failure to maintain strict controls risks costly outbreaks requiring expensive eradication efforts later—and potential reliance on foreign supplies instead of robust domestic production. The Senate and Congress must ensure USDA has the resources and authority needed for continuous surveillance and rapid response capabilities.
A Call for Accountability: Vigilance Must Outlast Diplomacy
The reopening plan is a test of whether U.S. agencies will prioritize facts over politics and act decisively if conditions change again. Our producers deserve transparency on inspection standards and timely updates about any resurgence risks crossing our borders.
As conservatives dedicated to protecting American interests, we must insist on accountability from all those charged with defending our livestock industries against biological threats tied directly to border management policies.
