The case in Andrews County included an infested dog. Another case included a goat in Gillespie County. by
Three more cases of New World screwworm were confirmed in Texas by the U.S. Department of Agriculture on Monday, bringing the total number of cases to five.
One new case is in Andrews County, nearly 400 miles north of Zavala County, where the first case was reported last week.
The new cases are in different animals. In La Salle County, about 80 miles southeast of Zavala, a calf has been infected. In Andrews County, a veterinarian submitted the samples from an infested dog. According to the Andrews Veterinary Clinic, the case was seen on Saturday, and neither the dog nor its owner is local to Andrews. The Animal and Plant Health Inspection Service, a USDA service, said the dog is from a household in Lea County, New Mexico, making it the state’s first screwworm case.
The APHIS said the dog’s travel history and exposure history is unknown. The USDA is inspecting additional animals in the household and increases outreach.
The third case is in a goat out of Gillespie County, about 170 miles north of Zavala County.
The U.S. Department of Agriculture, along with Gov. Greg Abbott, held a joint press conference at the Knipling-Bushland U.S. Livestock Insects Research Laboratory in Kerrville where they revealed their “War on Screwworm” campaign with a slogan declaring “Inspect, Report, and Protect,” warning Texans the situation is expected to get worse.
U.S. Agriculture Secretary Brooke Rollins said the U.S. Department of War is making the New World screwworm infestation one of its top priorities by putting a military commander in charge of helping accelerate resource gathering, construction and research.
“South Texas ranchers are the front line of this battle against screwworm,” Rollins said, emphasizing the importance of reporting any screwworm incidents.
Abbott also said the state’s emergency command center will be open 24/7 with specialists from Texas A&M and state personnel to ensure all incidents are reported and tracked.
“We have beaten this before and we will do it again,” Abbott told a room filled with reporters and ranchers.
Rollins said there is currently no timeline in defeating New World screwworm, but with the partnerships between federal, state and local officials, it shouldn’t take multiple years like it has in the past.
“Some would say it’s impossible, but this is Texas,” Rollins said.
The screwworm is a parasitic fly that infests living mammals, especially cattle. State and federal officials are racing to contain the insect that has been on a northern migration track since at least 2023. Agriculture leaders fear if the fly is not contained, it could cost the state’s cattle economy at least $1.8 billion.
Dudley Hoskins, under secretary for Marketing and Regulatory Programs with the USDA, urged animal owners to stay vigilant, check their animals closely and report anything that looks suspicious.
“We need the partnership of animal owners across the region,” Hoskins said in a statement. “Together, we can protect our livestock, our communities, and the health of animals nationwide.”
Rollins called out recent comments made by Agriculture Commissioner Sid Miller alleging producers and ranchers won’t report screwworm findings out of fear of being quarantined harmful to their efforts.
“Unserious comments from an unserious AG commissioner who only has a few months left,” she said.
The USDA is also exploring alternative options to combat screwworm including putting ivermectin in animal feed.
Rollins announced Monday that President Donald Trump appointed John Bellinger, a member of the Texas A&M University Board of Regents, to be the new senior adviser for New World screwworm preparedness. Bellinger is expected to help explore all available technologies to combat the screwworm. Bellinger was appointed to the A&M board in 2023, where he serves as chair of the committee on research.

Biden’s migrants brought in more than just crime, drugs and disease - these screw worms are bad news.
Yeah, we know. Crockett, Talarico and Al Green.
The FDA issued an Emergency Use Authorization (EUA) for over-the-counter Ivomec (ivermectin) injectable solution to prevent and treat flesh-eating New World screwworm (NWS) infestations in cattle.
It provides quick-acting, systemic protection when wounds appear, though it comes with a 35-day slaughter withdrawal period.
How Ivermectin Works on ScrewwormsSystemic Action:
Administered via subcutaneous injection (under the skin), the drug enters the bloodstream.
When feeding screwworm larvae ingest the treated blood, ivermectin disrupts their nervous system, causing paralysis and death.
Prevention:
A standard dose provides about 12 to 20 days of residual protection, which keeps vulnerable areas (like castration sites or calving wounds) clear of new infestations.
Key Usage GuidelinesTarget Species:
Authorized for cattle, though veterinarians and ranchers utilize macrocyclic lactones like ivermectin in off-label capacities for horses, swine, and sheep.Dairy & Veal
Restrictions:
Ivermectin is strictly not for use in female dairy cattle producing milk for human consumption or in calves that will be processed for veal.
Manual Care:
Medication alone doesn’t fix the wound. Ranchers still must remove the dead larvae, disinfect the area, and dress the wound properly to prevent secondary infections and fly re-strikes.
Regulatory Context
Because the screwworm was technically eradicated in the U.S. decades ago but has seen sporadic recent incursions near the Texas border, the FDA’s EUA grants ranchers immediate over-the-counter access to roughly $4 treatments to stop outbreaks before they devastate livestock.
Always refer to the official FDA Emergency Use Authorization for Ivomec for exact dosage calculations (typically ~200 micrograms/kg), or consult your local veterinarian for guidance on managing an active outbreak.
“We’re screwed!”
We all don’t like illegals, but human infection is extremely rare. Mexico has had a screwworm problem for years. We banned the live import of Mexican cattle over it. The bug can fly it is a fly after all and since it can also we lofted by winds too it was only a matter of time before it crossed the Rio. It has a natural vector in feral hogs , deer and any other mammal in the wild. South Texas is loaded with deer and hogs even if we treat the cattle those natural vectors ensure the fly breeds and breeds more.
The solution is how we beat it before all the way down to Panama the last time. Breeding billions of sterile male flies that get with a female who only breeds once thus ending that line. Kerrville is the lab that breeds those flies using radiation back in the day they are doing it again they have been releasing millions of male flies every other day in those counties.
It’s how we dealt with it in the mid-60s and we’ll do it again, but it’ll take a while.
The other solution was to use insecticide (DDT I presume)
on the cattle, but that practice is now banned by the EPA.
Throw illegals over the Wall!
While human are not a normal vector for screw worm spread, the massive number of 12 million people infiltrating our borders in a completely uncontrolled fashion provides multiple vectors for screw worm spread across the border, not just by human infection.
That said, while human infection is rare under normal circumstances having 12 million illegal aliens who have traveled from South and Central America through the Darién Gap and through about a thousand miles sleeping outside in rural and jungle terrain with poor hygiene conditions and in close proximity to animals that are vectors for screw worm you are going to have people acting as screw or vectors - either via direct screw worm infection or screw worms acting as riders on migrants or their gear.
While the percentages are statically low, when you that many millions of people involved, the large number of people even a statistically low percentage of incidents give a large number of people acting as vectors due to the sheer volume of people involved.
In reality, the chaos and diversion of inspection assets caused by the illegal alien invasion are also largely responsible for the current screw worm infestation.
If you recall, border patrol assets were diverted to caring for children or providing “humanitarian support “ for the invaders.
A lot of stuff crossed the border in an uncontrolled and uninspected fashion under Biden, arguably by willful and intentionalmaction by the Democrats and Biden Admin.
A grave danger, to be sure. But for your entertainment, here is Ana tricks that lays the blame in part on…… can you guess?

Has there been reports of humans with screwworm infections on the increase in border states in the last five years?
