A flesh-eating parasite gave Washington a reason to close the southern border to live cattle. Fifteen months later, the parasite is here anyway — in Texas, hundreds of miles from the port that stays shut. What the closure did accomplish is quieter and far more permanent: it is dismantling the American beef industry piece by piece. Our packing plants are closing. Our feedyards are going dark. Our herd is the smallest it has been in 75 years. And the business we are losing is not vanishing — it is moving to Mexico, into the hands of the one company positioned above all others to take it: SuKarne, whose founder has been named in a Pentagon-commissioned report as a possible member of the Sinaloa cartel’s financial network. This is the story of how that happened, told through the record itself. Every claim below links to its source.
Start with the buildings, because buildings don’t lie. In January 2026, Tyson permanently closed its beef plant in Lexington, Nebraska — roughly 3,200 jobs and about 5% of U.S. slaughter capacity, gone. It was the first major permanent closure of the crisis, and Tyson said plainly why: an “acute shortage of cattle.”[2] The company now projects a beef-segment operating loss of up to $600 million for the year and calls the region a “supply desert.”[1]
Then the dominoes. JBS shuttered its Riverside, California plant (374 workers) and cut shifts across its Midwest footprint[2]; months later it announced the closure of its Souderton, Pennsylvania plant — another ~2,000 head a day.[4] Cargill locked out roughly 1,700 workers at Fort Morgan, Colorado. Add a strike at JBS’s Greeley plant and the disruption reached a meaningful slice of national beef-processing capacity.
It isn’t only the packers. The feedyards that supply them are dying too. Lubbock Feeders — a 50,000-head Texas yard that fed more than five million cattle over 70 years and sourced 60–70% of its animals from Mexico — announced it will close.[6] Texas Cattle Feeders warns the closed border could cost the Texas-Oklahoma-New Mexico region roughly one billion fewer pounds of beef in 2026 alone.[5]
“Packer closes. Livestock auction closes. Feedyard closes.”— The domino effect described by industry analysts as the closure drags on
This is not a dip. It is a structural amputation. The U.S. cattle herd is the smallest it has been in 75 years.[1] The closure erased roughly 1.5 million head of Mexican feeder cattle a year — about a 3.3% cut to national supply[2] — and the animal has become the scarce, expensive thing everyone is bidding against.
The Coalition for a Prosperous America put a blunt title on it: America’s Cattle Industry Has Been Gutted. Retail beef is up 22% since January 2025; Choice beef up 27%; live cattle up 37%; weekly slaughter down 6.5% year over year.[3] Ground beef hit a national average of $7.85 a pound.[1] Consumers feel it at the counter. Ranchers feel it as an industry contracting in real time.
The thing to hold onto: every one of those closed plants, empty pens, and lost jobs is capacity that does not switch back on when a port reopens. A herd takes years to rebuild. A shuttered plant may never reopen. We are not weathering a storm — we are losing the house.
Here is the sleight of hand. The border is closed to live cattle — but not to beef. While American feedlots starve, Mexican boxed beef keeps flowing north, and it has surged 23% even as our own plants close.[6][16] Picture it literally: while our pens sit empty, workers sort beef carcasses at an export slaughterhouse in Hermosillo, Sonora, bound for the United States.[7] USDA’s own report found the closure redirected about one million head into Mexican feedlots and lifted Mexican beef production 6%.[11]
And one company is built to capture almost all of it: SuKarne. SuKarne accounts for roughly 75% of all Mexican beef exports — Mexico’s largest cattle-feeding and processing company, and one of the largest beef packers in North America.[8] It was the first company in Mexico to move from selling carcasses to boxed beef, and trade coverage describes it as “equipped to expand its presence in the US retail market and beyond.”[9] It already shipped 110,000 tonnes of beef into the United States in a single year.[10] When the American market needs beef and American plants can’t supply it, SuKarne is the supplier standing there.
Mexico is not letting the moment pass — it is pouring concrete. President Sheinbaum announced an 831-million-peso program to build out high-quality meat production for Sonoran ranchers, framed explicitly as a response to the closure.[12] Sonora broke ground on a new livestock-industrial complex — feed, slaughter, quarantine — to capture value-added beef. Every dollar of that build-out is designed to make the shift permanent.
Even our “American” giant is foreign. JBS, the largest beef packer operating in the U.S., is Brazilian-owned — and it is riding out the crisis by leaning on its Brazilian and Australian plants to fill the gap while it closes American ones.[1] So follow the ownership: the market our ranchers built is being handed to Mexican and Brazilian companies, and the single biggest winner is a firm founded in Sinaloa.
The damage compounds, and most of it is one-directional. A closed plant is often gone for good — the equipment liquidated, the workforce scattered, the permits lapsed. A national herd rebuilt from a 75-year low takes years of breeding, not a policy memo. Meanwhile Mexico is building the plants, the quarantine pens, and the export capacity to serve the very market we’re vacating.[11][12] Each month the closure holds, the handoff hardens.
The bill is already enormous. Beef prices at record highs.[3] Thousands of jobs erased across Nebraska, California, Pennsylvania, and Colorado.[2][4] A billion pounds of lost production in three states.[5] A domestic eradication program that historically saved the U.S. cattle industry an estimated $2.3 billion a year now overshadowed by a border policy working against it.[15] Run this out another year and “recovery” stops being the word. “Replacement” is.
Now the part no one in Washington wants to say out loud. The screwworm did not arrive on the back of an inspected, ivermectin-treated feeder steer crossing at Douglas. By the mainstream account, it arrived the way contraband always does — through illegal, unregulated cattle movement. CNN framed the comeback bluntly: a resurgence driven by organized crime.[13]
The industry coverage is even blunter. Beef Magazine: “The smoking gun points to drug cartel cattle. Call it narco-ranching.”[14] An estimated 800,000 head are smuggled across the Guatemala-Mexico border every year[14][16], entering with falsified papers and bogus ear tags; Mexican animal-health experts believe that smuggling helped bring the screwworm north in the first place.[15]
American ranchers have been pointing at exactly this. The people closest to the herd blame the illegal, cartel-linked cattle trade — not the legal one. A coalition of nearly 200 ranch and farm groups pressed USDA to act[15]; R-CALF has argued the border must stay shut until the pest is eradicated in Mexico[15]; and even USDA’s Secretary told the Senate the spread came from “the Mexican cartels with the illicit cattle traffic.”[17]
So here is the question that writes itself: if the threat is illegal cartel cattle, why is the punishment falling on the legal, inspected trade — while the business flows to the Mexican packer with the deepest documented ties to the cartel itself?
This must be stated carefully, and it will be. SuKarne was founded and is led by Jesús Vizcarra Calderón.[10] The following are matters of public record, each attributed to its source:
The essential caveat, in fairness and for accuracy: Jesús Vizcarra has never been charged with or convicted of any crime. No link to the cartel has been legally established. He has denied that any illicit money ever entered his companies. These are documented allegations and associations — not proven facts — and they are presented as such.
But allegations are exactly what a border policy this consequential should weigh. We are told the closure protects America from a threat that rides in on cartel-moved cattle. The effect of that same closure is to route billions of dollars in beef business to a Mexican company whose founder sits in a Pentagon-commissioned report on cartel finance. At a minimum, the public is owed an answer: who, precisely, are we handing our market to — and did anyone at USDA ask?
The closure has never behaved like science. It has behaved like politics. USDA’s own experts named Douglas, Arizona the lowest-risk port and reopened it on July 7, 2025 — about 900 head crossed. Three days later, USDA slammed it shut again, citing a screwworm case in Veracruz on the opposite side of Mexico, roughly 370 miles away (no published scientific basis as a port-closure metric) — and the reversal landed days after a coordinated lobbying campaign by R-CALF and 18 allied groups.[24]
Then the pattern set in: “not ready” in November, a teased reopening “in two to four weeks” in March, the functioning Nogales port left out of the conversation entirely.[25] By March 2026 the Secretary was no longer describing the closure as animal-health protection at all — she was calling it leverage, crediting it with making Mexico “better partners” under USDA “pressure,” “metrics,” and “accountability.”[26]
The distances don’t hold up as a standard, either. The Secretary’s public case rests on mileage — “800 miles,” “200 miles” — but USDA has never published a scientific standard that turns a distance into a port’s open-or-closed status, and its own stated criterion is a “systemwide” judgment of Mexico, not a regional one. Ask the question that ends the debate: show me the published risk assessment that turns miles into port status. No one at USDA can answer it — because it does not exist.
The framing didn’t stay in the hearing room — it metastasized. After the Secretary tied the pest to “open borders” and cartels, a U.S. senator went on television and claimed migrants carried the parasite in on their pets and “flesh.” Newsweek found no evidence linking human migration to the outbreak[22]; the CDC reports zero locally acquired human cases and says screwworm is not transmitted person to person.[23] The real vector — illegal animal movement — was documented all along.[13]
Put the pieces together and the shape is unmistakable. Six threads, each backed by the links above:
1. We are losing plants, jobs, and the herd itself. Tyson Lexington gone; JBS Riverside, Souderton, and Memphis; Cargill’s lockout; Lubbock Feeders closing; the herd at a 75-year low.

6. The closure behaves like politics, not science. Douglas reopened on the science, then reclosed on a case 370 miles away days after lobby pressure; reframed as “leverage”; the mileage standard doesn’t exist.

The question, restated for anyone willing to dig: Was this ever science-based animal-health policy — or did it become a machine for moving America’s beef industry to Mexico, enriching a cartel-linked company, and raising prices on American families? The record above is enough to justify asking in public.
