The U.S. Department of Agriculture confirmed New World screwworm larvae in a 3-week-old calf in La Pryor, Texas, approximately 80 km from the Mexico border. This marks the first such detection in Texas since 1966, prompting a 20-kilometer quarantine zone. No additional U.S. cases have been reported.
The incident reflects climate-driven pest range expansion requiring sustained federal investment and international sterile-fly cooperation rather than solely reactive measures.

Libertarian
Quarantines impose top-down restrictions on property rights and economic freedom, favoring centralized authority over decentralized or market-driven approaches.
“Individual liberty versus state inspection powers”
Devil's Advocate
All perspectives accept border proximity as explanatory without evidence on transmission and overlook that zero additional cases exist despite the broad quarantine.
