Next Step in the Screwworm Fight: USDA Announces Opening of Sterile Fly Dispersal Facility in Tampico, Mexico

Thu, 13 Nov 2025 19:31:40 GMT

USDA announced Thursday the opening of a sterile fly dispersal facility in Tampico, Mexico. The Tampico facility will allow USDA to disperse sterile flies aerially across northeastern Mexico, including in Nuevo Leon. This announcement is the next milestone in the fight against New World screwworm (NWS).

“The opening of the Tampico sterile fly dispersal facility is another incredibly important tool in our arsenal to stop the spread of screwworm. The facility will ensure flexibility and responsiveness in northern Mexico, giving us a greater ability to drop sterile flies and continue to push the pest south,” said U.S. Secretary of Agriculture Brooke Rollins in a press release . “Stopping the spread of screwworm is a top priority for the entire Trump administration.”

Last week Rollins met with Mexican President Claudia Sheinbaum and her counterpart Secretary Julio Berdegue on the joint response to NWS.

“We are boosting our efforts and completing a joint review of our screwworm operations in Mexico to ensure our protocols are being followed,” she says. “As we enter the winter months , we continue to prioritize the response in Mexico and the rest of our five-pronged plan to protect U.S. livestock and the livelihoods of American farmers and ranchers.”

A proven method for NWS eradication is releasing sterile male flies to mate with wild females collapsing the population over time. There are two methods of dispersing sterile insects – aerial dispersal and ground release chambers. Aerial operations are preferred because they allow for dispersal at a steady rate through a large area and also because sterile insects may be dispersed in areas that are unreachable from the ground. Ground release chambers are used when there’s a need to quickly deploy sterile insects outside of the dispersal facility range.

According to the press release, USDA continues to disperse 100 million sterile flies per week in Mexico, but until now, aerial operations have been limited to southern Mexico, necessitating the use of ground release chambers in more northern areas of the country. Mass production and targeted dispersal of sterile flies remain critical components of our effective response.

Although Mexico continues to confirm new cases of NWS, the overwhelming majority of these remain in the far southern part of the country, with no significant northward expansion over the past several months. Should that change, the Tampico facility will allow USDA to immediately tackle any cases that occur elsewhere in Mexico.

The two northernmost detections (approximately 70 and 170 miles from the U.S. border, respectively) occurred in Nuevo León, on Sept. 20 and Oct. 5 , in young cattle transported from Chiapas, Mexico.

Neither case is still active and there have been no additional detections of NWS flies in traps or cases in animals in Nuevo Leon. USDA continues to disperse sterile insects in Nuevo Leon, and will now transition from ground release chambers to aerial dispersal in those areas.

USDA produces sterile flies for dispersal at the COPEG facility in Panama. USDA is also investing $21 million to support Mexico’s renovation of an existing fruit fly facility in Metapa — which will double NWS production capacity once complete. With ongoing support from APHIS technical experts, Mexico anticipates this sterile fly production to begin as soon as summer 2026.

To expand our domestic response capacity, USDA has also begun construction on a sterile fly dispersal facility at Moore Air Base in Edinburg, Texas, that is projected to begin operating in early 2026. APHIS is also expediting design and construction of a sterile fly production facility in southern Texas, with a targeted maximum capacity of 300 million sterile flies per week.

USDA continues to work with Mexico’s agriculture authority, SENASICA, to implement the collaborative NWS Action Plan and guide trapping, surveillance and movement protocols to help stop the northward spread of NWS.

Trade Mission While In Mexico

While Rollins was in Mexico last week, she also led the largest U.S. Department of Agriculture agribusiness trade mission in history. During the mission, 41 U.S. businesses, 33 cooperators and agriculture advocacy groups, six state departments of agriculture, and 150 participants conducted more than 500 business-to-business meetings during the three days.

According to a USDA press release , “This was a critical opportunity for American business to further trade ties and for USDA to continue its aggressive response to NWS in Mexico and continue to hold Mexico accountable for its commitments to the 1944 Water Treaty.”

Mistrial Declared in Arizona Rancher’s Murder Trial

Thu, 26 Sep 2024 18:42:45 GMT

An Arizona judge declared a mistrial in the murder case of rancher George Alan Kelly, 75, who was accused of fatally shooting a migrant on his property near the U.S.-Mexico border.

Superior Court Judge Thomas Fink said the decision was made after jurors failed to reach a unanimous decision after two full days of deliberation.

Following the declaration, Kelly’s defense attorney Kathy Lowthorp revealed outside the courthouse to the media that there had only been one guilty juror in the group, which was why the defense team pushed for deliberations to continue.

“There was one hold out for guilty, the rest were not guilty. So seven not guilty, one guilty,” Lowthorp stated. “We believe in our gut that there was no way the state proved beyond a reasonable doubt.”

Kelly had faced second-degree murder in the Jan. 30, 2023, shooting of Gabriel Cuen-Buitimea, 48, who lived just south of the border in Nogales, Mexico. Kelly had earlier rejected an agreement with prosecutors that would have reduced the charge to one count of negligent homicide if he pleaded guilty.

“It is what it is, and it will be what it will be. Let me go home, okay? That alright with y’all?” Kelly told reporters outside the courthouse following the mistrial. “I will keep fighting forever. I won’t stop.”

Judge Fink had told jurors that if they could not reach a verdict on the second-degree murder charge, they could try for a unanimous decision on a lesser charge of reckless manslaughter or negligent homicide.

The Santa Cruz County Attorney’s Office can still decide whether to retry Kelly for any charge or drop the case all together.

A status hearing was scheduled for next Monday afternoon, when prosecutors could inform the judge if they plan to refile the case.

Arizona Border Rancher Accused of Killing Migrant, Now Held With $1 Million Bond

An Arizona rancher has been arrested in connection with the death of a Mexican national who was shot and killed on the rancher’s property, literally yards north of the Mexican border.

(Farm Journal)

George Alan Kelly, 73, was charged with first-degree murder in the death of Gabriel Cuen-Butimea, 48, from Nogales, Mexico. Authorities say Cuen-Butimea was shot Jan. 30 in a remote desert area near Kino Springs, a tiny hamlet in Santa Cruz County. Kelly is being held on a $1 million bond.

Law enforcement have not divulged a motive for the shooting, and details remain sketchy. The incident, however, could develop into a powder keg and further escalate the tense political issue regarding the U.S.-Mexican border.

Here’s what we know. Kelly lives with his wife on their ranch – Vermilion Mountain Ranch – and routinely see migrant trespassers. The couple have reported they fear members of the drug cartels and their heavily armed soldiers trafficking people and drugs.

On the day of the shooting, a sheriff’s dispatch reported a call at around 2:40 p.m. from U.S. Border Patrol about a “possible active shooter” in the area of Sagebrush Road, which is Kelly’s address. CBP apparently received a report from a witness about a “group of people running” and said he was “unsure if he was getting shot at as well.”

At around 5:50 p.m. on the day of the shooting, sheriff’s deputies received another report of shots fired at the property. By 6:42 p.m. they recovered Cuen-Butimea’s body. Authorities have said there was no weapon on the victim at the time, and investigators had collected two assault-style rifles from Kelly’s property in the aftermath to determine whether either was used in the shooting.

Cuen-Butimea was identified by authorities from his Mexican voter card, and his body was found approximately 150 yards from Kelly’s home. News outlets have reported U.S. federal court records “show Cuen-Butimea has had a history of illegal border crossings and deportations in and around Nogales, with the most recent documented case in 2016.”

While an investigation into the shooting is ongoing, officials have said they don’t have a clear motive and that they don’t think Kelly and Cuen-Butimea knew each other.

Under Arizona law, deadly force is allowed on one’s own property if the homeowner believes it “immediately necessary” to prevent trespassing. Other statutes — known as the “stand your ground” laws — also defend the use of physical or deadly force when a homeowner fears a threat and believes force is necessary.

At a preliminary hearing Jan. 31, Kelly asked a judge to reduce his bond so he could help his wife.

“She’s there by herself … nobody to take care of her, the livestock, nor the ranch. And I’m not going anywhere. I can’t come up with a million dollars.”

A GoFundMe account was established to help with Kelly’s legal fees, but the account was quickly taken down, FOX News Digital reports.

“GoFundMe’s Terms of Service explicitly prohibit campaigns that raise money to cover the legal defense of anyone formally charged with an alleged violent crime. Consistent with this long-standing policy, any fundraising campaigns for the legal defense of someone charged with murder are removed from our platform,” a spokesperson for GoFundMe said in a statement to Fox News Digital. “Donors who contributed to the fundraising campaigns for George Alan Kelly’s legal expenses have been fully refunded.”

An active fundraiser for Kelly remains on the Christian crowdfunding platform GiveSendGo which had raised over $16,000 on Friday morning.

“Neighbors say that he had been having difficulty keeping invaders out and say that Mr. Kelly would have acted in good faith,” the fundraiser’s organizer, Shannon Pritchard, wrote. “It is a tragedy that a simple farmer, who should be protected by the government, has been abandoned and had to defend himself.”
