The U.S. Department of Agriculture (USDA) has confirmed four cases of the flesh-eating New World screwworm in Texas and New Mexico, prompting international trade restrictions and an emergency response.
Key points
- Canada has implemented an emergency import ban on all livestock from Texas to prevent the spread of the parasite.
- The USDA is deploying millions of sterile flies via aerial release to disrupt the pest's reproduction cycle.
- A case involving a dog in Lea County, New Mexico, was reclassified as the state's first confirmed detection.
- Authorities have established 20-kilometer quarantine zones and increased fly trapping along the Mexican border.
Why it matters
The New World screwworm poses a significant threat to the livestock industry and animal health, potentially causing severe economic damage if not contained.
