The horse slaughter pipeline
Federal prosecutions have shown criminals using horse trailers to hide smuggled people and drugs, and horse businesses to launder cartel money.
One executive order puts the federal government on it.
The issues
This is no longer only an animal welfare issue. Slaughter-bound horses move through a loosely regulated network of auctions, dealers, holding pens, haulers and border crossings. Federal prosecutions have shown criminals using horse trailers to hide smuggled people and drugs, and horse businesses to launder cartel money. Every crossing is also a pathway for diseases like diphtheria and New World screwworm.
All of this risk serves a trade most Americans don't know exists. About 25,000 U.S. horses were exported for slaughter in 2025, roughly 0.4% of the nation's 6.6 million horses, to feed a foreign horse-meat market.
We are a coalition of horse and human advocates calling on DHS, CBP, USDA and federal law enforcement to close these gaps and end the export of American horses for slaughter.
01
Horse Plus reports that slaughter-bound transport routes can conceal criminal activity. Separately, federal prosecutions have shown criminals using horse trailers to hide smuggled people and drugs, and horse businesses to launder cartel money. Federal agencies should follow the evidence across state lines and international borders.
02
In June 2026, Oklahoma narcotics agents reportedly found approximately 350 pounds of cocaine in a trailer carrying six horses. In a separate New York case, a defendant admitted receiving methamphetamine shipments in horse trailers. Horse Plus also alleges that its investigators uncovered other methods of concealing drugs during equine transport; those allegations warrant investigation.
03
Federal officers found 32 people hidden in a compartment of a horse trailer carrying four horses at a Texas checkpoint. Horse Plus says its undercover sources also witnessed people concealed alongside slaughter-bound horses and reported sex-trafficking activity. Those additional reports require investigation, with victims protected.
04
A federal jury convicted participants in a conspiracy that laundered Los Zetas drug proceeds through American quarter-horse purchases and racing. Horse Plus separately reports concerns about cash-heavy auctions, false ownership trails, horse theft and extortion. Investigators should trace transactions and establish where crimes have occurred.
05
Horse Plus reports that nearly two dozen slaughter-bound horses tested positive for Corynebacterium diphtheriae. The CDC lists other diseases associated with horses that can affect people, including rabies, salmonella, anthrax, MRSA and New World screwworm. Public health and veterinary authorities should review the Horse Plus test results, determine whether the isolates produced toxin, and investigate possible sources of exposure.
06
USDA confirmed New World screwworm in Texas in June 2026. Cases were subsequently reported in horses in Texas and New Mexico in September. The parasite infests living tissue, making inspection, prompt reporting and appropriate animal-movement controls vital. The source of the horse infections remains under investigation.
07
When the paperwork disappears, so can the horses. Animals moved without proper identification, health records, inspections or lawful entry documents can slip through disease-control and enforcement systems, making it harder to trace where they came from, where they are headed and who is responsible. Horse Plus raises concerns about documentation gaps in slaughter-bound transport. Federal equine-import rules and state movement restrictions show why traceability matters.
08
The Horse Plus Legislative Coalition says its DNA testing identified horse meat sold to restaurants and food trucks in Texas and Florida. Separately, a U.S. research study detected horse meat in two ground-meat samples bought from online specialty sellers. Authorities should examine the coalition's test records, trace suspect meat, and enforce inspection and labeling laws.
On September 21, Agriculture Secretary Brooke Rollins convened a federal animal welfare Strikeforce roundtable attended by Health and Human Services Secretary Robert F. Kennedy Jr. Lara Trump also appeared at the event. USDA's announcement introduced its Animal Protection Bureau and originally named horses alongside dogs, saying the new team would support enforcement of both the Animal Welfare Act and the Horse Protection Act.
Then USDA revised the release. The current version removes the references to horses and the Horse Protection Act from its description of the initiative. USDA has reportedly said it did not intend to reclassify horses as companion animals.
So where do horses stand in this new enforcement effort? Horse advocates deserve a clear public answer.
1776
Horses carried the Continental Army, its guns and its supply trains through the war that made the country.
1860
The Pony Express crossed nearly two thousand miles of frontier in ten days, on horseback, and tied a young nation together.
1918
American horses shipped to Europe by the hundreds of thousands and hauled the guns of the First World War.
2026
In the Year of the Horse, as America marks 250 years, tens of thousands of American horses are trucked across the border to be slaughtered.
