New World Screwworm · current zones

Check the pickup location before the pet moves.

Texas and New Mexico currently have NWS infested-zone controls. The exact zone matters because it can trigger inspections, movement certificates, permits, treatment requirements, or tighter destination-state paperwork.

⚠ Texas and New Mexico both have active zone controls

USDA directs travelers and transporters to the state animal-health authorities for current infested and surveillance zone boundaries. An individual animal case can be inactive while the surrounding infested zone remains in force.

Do not rely only on a county name. Zone boundaries can cover only part of a county and can change as detections, surveillance, and release criteria change.

Official zone tools

Texas and New Mexico are the current U.S. zone states.

Use the official state tools below before dispatch. If a pickup is near a boundary, confirm with the state animal-health office rather than guessing.

Texas: if the pickup is inside an infested zone

All warm-blooded animals in a Texas infested zone, including dogs and cats, may not move out of the zone without prior authorization from TAHC.

What Snout Route must doContact TAHC or an NWS Certified Inspector before pickup, arrange the required inspection, and obtain the movement/treatment certificate before the pet leaves the zone.
Texas NWS Status & Orders

New Mexico: if the pet is in or leaving an infested zone

New Mexico requires special pre-movement inspections for all warm-blooded animals moving within or exiting an NWS infested zone.

What Snout Route must doHave the pet inspected before movement by a New Mexico-accredited veterinarian and obtain the required animal movement certificate before travel within or out of the zone.
New Mexico Movement Requirements

Destination states can add requirements even without their own zone

A destination state can impose extra paperwork because a pet came from Texas, New Mexico, an infested zone, or an adjacent/high-risk area.

  • California: recent veterinary inspection, eCVI, and entry permit for companion animals from a state with an active NWS zone.
  • Florida: 5-day OCVI rules for high-risk origins; infested-zone origins add movement authorization and treatment documentation.
  • Indiana: movement certificate, 5-day CVI, and NWS treatment for dogs/cats from infested zones.
  • Michigan, Minnesota, Missouri, Utah, Washington, and Wisconsin also have extra NWS-related pet movement requirements.

Florida uses a broader high-risk definition

Florida's emergency rule can apply even when a pet is not inside the Texas or New Mexico zone polygon.

  • Texas and New Mexico areas outside designated infested counties can still be treated as high-risk.
  • Florida also identifies Cochise, Graham, Greenlee, Pima, and Santa Cruz counties in Arizona as high-risk.
  • Warm-blooded animals from those high-risk areas need an OCVI based on an inspection within 5 days with Florida's required NWS statement.

🇨🇦 Traveling to Canada with a dog or cat?

Canada's current NWS import restrictions do not list dogs or cats as restricted species. A dog or cat coming from Texas, New Mexico, or an NWS infested zone is not currently subject to an additional CFIA NWS import prohibition solely because of that origin.

What changes for a dog or cat?Follow the normal Canadian pet-entry requirements. Before departure, still complete any U.S. origin-state NWS movement requirements that apply to getting the pet out of an infested zone. Inspect the pet for wounds or signs of screwworm and seek veterinary care immediately if infestation is suspected.

Important: Canada's NWS restrictions do apply to certain other live-animal species. CFIA currently lists Texas as the U.S. affected state for those restrictions. For covered species, origin in or transit through an affected state can make the animal ineligible for entry.

Dispatch checklist1) Check the exact pickup location against Texas or New Mexico zone information. 2) If inside a zone, complete the origin-state inspection/movement requirements. 3) Check the destination state's NWS action box on the State Requirements page. 4) Recheck close to departure because emergency orders can change quickly.
