Oklahoma Warns Horse Owners to Stay Alert for New World Screwworm

Published: September 13, 2026  ·  Status: Current animal-health alert

Oklahoma animal-health officials say New World Screwworm has been confirmed in Texas and New Mexico but not in Oklahoma, and they are asking animal owners and veterinarians to remain vigilant.

What changed

For horse facilities, the immediate concern is wound monitoring and rapid reporting rather than panic. NWS larvae develop in wounds, so routine injury checks take on added importance when the pest is active nearby.

Why equine operations should care

Barns that haul south or west should also watch destination-state and return-entry requirements because those can change faster than ordinary annual health paperwork.

What operators should do now

• Inspect wounds during daily horse checks.
• Contact a veterinarian promptly when suspicious larvae or unusual wound progression is seen.
• Check travel requirements before interstate movement.
• Record recent travel for horses arriving from affected areas.

Keep written barn procedures, horse records, transport documents, and client communications aligned with the rules that actually apply to your operation. For related documentation, review the horse boarding contracts guide, Barn Setup, and the MyStableForms state package library.
