USDA halts live animal imports through US-Mexico border
- On May 11, 2025, U.S. Agriculture Secretary Brooke Rollins announced a suspension on the entry of live cattle, horses, and bison across ports of entry along the southern border due to concerns over the New World screwworm pest.
- The suspension responds to the detected northward advance of the New World screwworm, a parasitic fly whose maggots cause severe damage to livestock and wildlife.
- Despite a recent U.S.-Mexico agreement on pest control, the USDA said earlier efforts were insufficient, and the screwworm was found about 700 miles south in Oaxaca and Veracruz.
- Rollins highlighted the danger by recalling that when this destructive pest previously entered the U.S., it required three decades for the cattle sector to fully bounce back, while Mexico’s Agriculture Secretary Julio Berdegué criticized the decision as unacceptable.
- The suspension, effective immediately and reviewed monthly, may cause economic impact on both nations while aiming to slow the pest's progression and protect livestock health.
