KERVILLE (AP) — Two more cases of the New World screwworm have been confirmed in Texas, demonstrating the difficulty of stopping the spread of a pest that could potentially devastate the nation’s cattle industry, the U.S. Department of Agriculture announced Monday.

The screwworm is actually a fly, which produces a larvae that eats live flesh instead of dead material. Females lay their eggs in open wounds of any warm-blooded animal such as cattle, but wildlife, pets and occasionally even humans can be infested.

The USDA said the new cases were found in a calf and a dog, hundreds of miles apart in La Salle and Andrews counties. That brings the total number of confirmed cases to four. The screwworm was first discovered in a 3-week-old calf last week, and a second case was found only miles away in a young calf.

“While we address these instances that require immediate attention, and continue to sample suspected cases, we are simultaneously working to eradicate the pest entirely,” Dudley Hoskins, the USDA’s marketing and regulatory undersecretary, said in a statement.

Before it was eliminated in the U.S. in the 1960s, the fly was an annual warm-weather scourge of cattle ranchers.

The USDA and the U.S. cattle industry have been racing to prevent an infestation since the pest was detected in Mexico late in 2024 after decades of being contained at the southern end of Panama.

The government fights the fly by breeding sterile male flies, which then mate with wild females that only mate once in their monthslong life. By mating with sterile flies, the females don’t produce more flies and outbreaks can eventually be halted.

The USDA has announced plans to increase sterile fly production in plants outside the U.S. while it builds a fly factory in Texas.

USDA Secretary Brooke Rollins will be briefed on the infestation Monday afternoon at the U.S. Livestock Insects Research Laboratory in Kerville, Texas.

BROADDUS, Texas (KETK) – Broaddus ISD has announced that one of their former teachers has been referred to law enforcement over allegations that they had an inappropriate relationship with a student.

According to the district, administrators received information on Thursday that alleged a teacher was having an inappropriate relationship with a student involving “grooming behavior” and possible physical contact.

Broaddus ISD immediately notified the proper law enforcement authorities so they could investigate the allegations. The teacher is no longer employed by Broaddus ISD.

The district said there was no indication that there was any threat to any students.

“Broaddus ISD remains committed to providing a safe and supportive learning environment and will continue to cooperate fully with law enforcement and all appropriate authorities throughout the investigative process,” Broaddus ISD said. “The safety and well-being of our students remain our highest priority. We appreciate your understanding and support as this matter proceeds. Due to the ongoing investigation and privacy laws, the district will not be providing additional details at this time.”

NACOGDOCHES, Texas (KETK) – One person was injured in a shooting that happened near Carpenter Elementary School in Nacogdoches on Sunday.

According to Nacogdoches Police Department, officers responded to 1005 Leroy Street near Carpenter Elementary School at around 12:52 a.m. because of reported gunshots near there.

Officers arrived at the scene and were told that a person was shot and then taken to a local hospital for treatment. The officers went over to the hospital and were told that an unknown person had shot the victim with a firearm.

One person the officers talked to during their investigation was arrested after they were found to be in possession of a controlled substance. Anyone with information about the shooting can contact Nacogdoches PD at 936-559-2607.

APPLEBY, Texas (KETK) – Nacogdoches County officials said one man has died after his ATV ran into a fallen tree on Saturday near Lake Naconiche.

According to Nacogdoches County Precinct 3 Constable Roger Dudley, a man was driving his ATV on County Road 134, north of Appleby and to the south of Lake Naconiche, just before 11 p.m. on Saturday when the ATV struck a tree that fell across the county road.

Hitting the tree caused the ATV to flip into the air, ejecting the driver before the ATV landed upside down, according to Dudley. The Central Heights/Appleby Fire Department, the Nacogdoches Fire Department and the Nacogdoches Ambulance Service responded to the crash scene and attempted life saving measures but the victim’s injuries were too serious.

Dudley said the victim’s wife informed his office that her husband did not survive his injuries from the crash. Dudley asked the public for many prayers for her family following this loss.

Texas Gov. Greg Abbott expressed concern Friday that a new factory isn’t expected to start breeding sterile New World screwworm flies for more than a year as a big part of the effort to stop its flesh-eating larvae from threatening the $113 U.S. billion cattle industry.

Abbott pledged Texas will help the U.S. Department of Agriculture accelerate construction of the $750 million breeding facility outside Edinburg, Texas, about 20 miles (32 kilometers) north of the U.S.-Mexico border. He said Texas is willing to spend its own funds to see that construction is “24 hours a day, seven days a week.”

Without greater sterile fly production, Abbott said during a news conference in the state capital of Austin, “We cannot make it through a second summer.”

The USDA confirmed an infestation of New World screwworm fly larvae this week in a 3-week-old calf in La Pryor, Texas, about 100 miles (161 kilometers) southwest of San Antonio and 50 miles (80 kilometers) from the Mexico border. It was the first case confirmed in Texas since 1966.

The department on Friday announced a second confirmed case found in a one-month-old calf in Zavala County, Texas, about 5.6 miles (9 kilometers) from the first case.

The new factory in Texas is the larger of two fly-breeding facilities funded by the USDA.

Separately, the USDA invested $21 million in converting a site in southern Mexico from breeding fruit flies to breeding screwworm flies. That factory is expected to start producing flies next month, eventually 100 million a week.

The other factory in Texas will be the size of two Costco stores, said Rear Admiral Michael Schmoyer, a member of the USDA’s screwworm response team. It is expected to produce up to 300 million flies a week.

Officials believe both factories are needed to eradicate the fly from the U.S., Mexico and Central America.

Schmoyer said the federal government has already shortened the planning and construction timeline considerably — drafting plans in a few months rather than taking a year, for example. U.S. Agriculture Secretary Brooke Rollins said the USDA hopes it will be running sooner than its planned November 2027 opening date.

But Abbott said Texas is determined to have construction go even faster.

“This is going to spread over the course of the summer,” he said of the fly.
Infestation hits among record beef prices

An untreated infestation of New World screwworm fly larvae can kill an animal, but there are now a dozen government-approved medications to treat livestock. Federal and state officials have been quick to stress that fly’s larvae — which feed on living material — do not infest meat or fruit.

“There’s a food production issue, but not a food safety issue,” Abbott said.

Derrell Peel, a professor of agribusiness at Oklahoma State University, said the beef supply isn’t likely to be affected unless officials restrict cattle movement more than locally or unless infestations appear in feedlots or other places where cattle are concentrated. He does not expect that to happen.

“It’s probably not a major market issue,” he said.

Consumers are paying record beef prices because of a tight cattle supply, and Peel expects prices to rise even further when ranchers take heifers out of the supply chain to rebuild their herds. But he said the arrival of the screwworm in Texas “doesn’t change the supply fundamentals.”

Screwworm outbreaks in Mexico starting in 2024 prompted U.S. Agriculture Secretary Brooke Rollins to close U.S. ports of entry to its cattle in May 2025. Mexican imports were once about 1.2 million animals a year and dropped about 80% last year, according to industry statistics.

But Peel said Mexican imports were only about 3% of the U.S. cattle supply.

“It’s been just one more thing on top of others,” he said, not a major driver of prices.

Breeding sterile flies has eradicated pest before

The New World screwworm fly was an annual, warm-weather scourge of U.S. cattle ranchers from at least the 1930s through the 1960s.

But breeding sterile flies and dropping swarms of them from planes eradicated it from the U.S. by the early 1970s, except for a brief outbreak among deer in the Florida Keys in 2016 and a case confirmed in a Maryland man who traveled to El Salvador last year. Until an outbreak in Panama in 2023, the fly had been considered eradicated outside its remote, southernmost region bordering Colombia.

Females mate once in their monthslong lives, and if they breed with sterile male flies, their eggs won’t hatch after being laid in open wounds and mucous membranes of warm-blooded animals, including cattle, wild mammals, household pets and humans.

Once the U.S. and other nations eradicated the fly years ago, they shut down fly-breeding facilities until there was only one left in the Western Hemisphere, in Panama. It can produce about 117 million flies a week.

However, past eradication efforts needed about 500 million flies a week, said Schmoyer, a member of the USDA’s screwworm response team, during Abbott’s news conference.
With fly drops, officials try to predict future

Schmoyer estimated that the USDA already has dispersed 130 million flies in Texas since January, most of them from planes, and those drops are now about 4 million a week. It also is releasing another 4 million a week in the ground as pupae, which are flies in the stage between larvae and adult.

But, even with those millions of flies, the USDA must be strategic about where to disperse them, Schmoyer told reporters. Federal and state officials are using scientific models to predict how the fly will move.

“In essence, it’s not where the flies are today, but where they could be weeks from now,” he said.

Part of the science involves traps, and Texas State Veterinarian Bud Dinges said they’ve been deployed up to 120 miles (193 kilometers) away from La Pryor to monitor the fly’s movement.
