Illegal horse smuggling across the U.S.-Mexico border is raising concerns that animals bypassing Veterinary inspections could undermine efforts to control New World screwworm. Authorities recently intercepted six horses that had crossed the Rio Grande illegally near Redford, Texas, avoiding required health certifications, inspections, and quarantine measures. Although those horses were not infected, Mexico has confirmed more than 2,000 equine screwworm cases since 2024.
Officials say smuggling networks move horses, cattle, dogs, and exotic animals through remote border areas, potentially allowing infected animals to travel farther than the parasite could naturally. Texas authorities have intercepted dozens of smuggled horses, while experts warn many animals likely cross undetected. U.S. officials have not linked any confirmed screwworm cases directly to smuggling, but scientists and veterinarians say undocumented animal movements create significant disease-transmission risks because the animals avoid Veterinary inspection and treatment. A widespread Texas outbreak could cause up to $1.8 billion in economic damage.
