New World screwworm in sheep

ENGLEWOOD, CO – Sheep producers are being encouraged to take proactive steps following the confirmation of New World screwworm (NWS) in the United States.  On Tuesday, the U.S. Department of Agriculture (USDA) confirmed the fifth and sixth cases of active New World screwworm, detected in a goat in La Salle County, Texas.

New World screwworm is a serious livestock pest that can affect sheep, cattle, goats, wildlife and other warm-blooded animals. Because early detection and rapid response are critical, The American Sheep Industry Association (ASI) has developed a producer-focused reference guide designed to help sheep operations understand the risks and prepare before the pest reaches their area.

The American Sheep Industry Association (ASI) Guide includes information on:

  • What producers should do now to protect their operations.
  • How New World screwworm affects sheep and other livestock.
  • Warning signs and symptoms to watch for.
  • Practical steps to minimize risk.
  • Veterinary treatment considerations.
  • Important contacts and additional resources.

ASI says the guide is intended to provide producers with the information they need to recognize potential cases and work with veterinarians and animal health officials if concerns arise.

Sheep producers are encouraged to review the guide and incorporate recommended biosecurity and monitoring practices into their operation’s management plan. As New World screwworm surveillance and response efforts continue, staying informed remains one of the best tools available to livestock producers.
