AHI Veterinarian Comments on New World Screwworm & Pet Health

The current risk of New World Screwworm to most pets remains low, but awareness and early action are important.

“Pet owners in areas with recorded outbreaks are encouraged to regularly check pets for cuts, bites, or other wounds,” said Ellen Hart, DVM, vice president of regulatory and international affairs at the Animal Health Institute (AHI). “They should also keep injuries clean and watch for signs that a wound is worsening rather than healing, such as swelling, unusual discharge, foul odors, or persistent licking by the pet.”

The U.S. Animal and Plant Health Inspection Service (APHIS) emphasizes that protecting pets and livestock from wound-causing parasites, such as flies and ticks, is a vital preventive measure. AHI supports this approach, recognizing the essential role parasiticides play in safeguarding livestock and pet health. We recommend using these products as directed and in consultation with a veterinarian to ensure proper protection or treatment of NWS.

Concerning wounds or animal behavior should be conveyed to your veterinarian promptly, and pet owners are urged to avoid diagnosing or treating suspected screwworm infestations themselves. “Your veterinarian can recommend the most appropriate preventive products and treatment options for your pet based on where you live and your animal’s individual needs,” continued Hart. “Using medications only as directed and under veterinary guidance helps ensure pets receive safe and effective protection.”

Veterinary professionals, animal health companies, and federal and state officials are actively addressing this parasitic threat. Staying informed, keeping pets on veterinarian-recommended preventive care, and seeking prompt veterinary attention for suspicious wounds are the best steps pet owners can take to keep their pets safe.
