Oklahoma regulators find elevated thyroid levels in 68 Remington Park horses

Sixty-eight Remington Park horses tested by Oklahoma regulators showed findings consistent with thyrotoxicosis, a result that turned an emergency horse-welfare probe into a credibility test for one of the state’s biggest racing meets. The Oklahoma Horse Racing Commission’s order covered 171 horses, and the findings immediately raised questions for owners, trainers, bettors and fans watching entries and form lines in Oklahoma City.

The commission issued the Emergency Protective Order on April 22 after reviewing evidence, reports, video recordings and veterinary opinions tied to horses that appeared in extreme distress after racing. Stewards said they saw an abnormal and materially elevated pattern of severe post-race distress, including horses that could not safely leave the track under their own power and had to be transported off the racing surface. The horses were placed on the State Stewards’ List and barred from entering or competing until they met the order’s requirements and were cleared by further written action.

By June 3, the commission said 96 of the horses had been evaluated and 68 showed thyroid findings consistent with thyrotoxicosis. Oklahoma officials said the condition is exceptionally uncommon in horses and can trigger elevated heart rate and respiration, hyperthermia, fatigue, weakness, muscle tremors, stiffness and, in severe cases, collapse. That is why the issue has landed as more than a paperwork dispute. It goes straight to whether recent performances at Remington Park reflected normal competitive effort or something that compromised the horses’ ability to race safely.

The emergency order touched three major trainer groups: 62 horses tied to Jed Vane, 52 to Josue Jacob Garcia and 57 to Leonardo Alcala. With nearly 3,000 horses competing at the meet, the commission’s action did not shut down the entire operation, but it did create a concentrated disruption in stalls, entries and stable patterns that horseplayers track closely.

Three Oklahoma County district judges later upheld the commission’s authority to keep the horses on the stewards’ list, though they modified some terms so the horses could be entered but not start until OHRC veterinarians and stewards were satisfied that doing so would not endanger welfare or racing integrity. The commission said removing a horse from the list requires a separate application for each horse, full disclosure of relevant records, independent veterinary review, diagnostic testing and an observed work followed by a veterinary assessment. Horses previously vanned off face even more scrutiny.

For a meet built on trust in the clock, the barn and the tote board, 68 positive findings is the kind of number that hangs over every start until the regulatory picture is clearer.
