Pet parents already know to watch for fleas and ticks, but veterinarians say there is a new parasite threat they should have on their radar this year: New World screwworm.
Dr. Casey Locklear with Animal Health joined We Are Austin to explain what pet owners need to know and how to spot warning signs early.
A Serious Threat Returning to Texas
Locklear said New World screwworm, which was eradicated from the United States decades ago, has reemerged in Texas, with one case also reported in New Mexico.
“As a Texas-based veterinarian and a fellow pet parent, New World screwworm is something that is concerning,” Locklear said. “It is a serious parasitic threat.”
She said pet owners should be vigilant and seek care quickly if they suspect their animal may be affected.
What to Watch For
New World screwworm can affect any warm-blooded animal and may appear as an unusual wound that gets worse over time.
“That wound may be enlarging,” Locklear said. “It could have some discharge, foul odor, and you may see some glistening movement in that wound.”
In severe cases, pet owners may even notice maggots, which are the larval stage of the parasite.
“If you see those signs, don’t panic,” she said. “First step: contact your veterinarian.”
She added that pet owners should ask their vet whether Cordelio Quattro CA1, the first and only conditionally approved treatment for New World screwworm in the U.S., may be appropriate for their dog.
Don’t Forget Fleas, Ticks and Tapeworms
Locklear also reminded pet owners that Texas pets are still at risk for more familiar parasites like fleas, ticks and tapeworms.
Fleas often show up as itching and scratching, while ticks can be harder to detect.
“Ticks can be a bit stealthy,” she said. “You may not see as many outward signs.”
Her advice: check pets for ticks every day after walks, paying close attention to the ears, neck, toes and hind legs.
Tapeworms can be even more difficult to spot.
“Oftentimes you won’t see any clinical signs,” Locklear said. “You may see something that looks like a grain of rice on your pet’s stool.”
