All Breeders’ Cup Samples Cleared; Assistant Starter Uninjured, Back To Work

All samples collected from 2021 Breeders' Cup horses have been cleared by the Kenneth L. Maddy Equine Analytical Chemistry Laboratory at the University of California, Davis.

All horses competing in Breeders' Cup races Nov. 5 and Nov. 6 at Del Mar were tested for TCO2 levels in blood. Post-race testing was performed for prohibited drugs on the first four finishers in all Breeders' Cup races and any additional random horses selected by the stewards consistent with California Horse Racing Board protocol. Post-race testing was done on both blood and urine samples.

The Maddy Laboratory's standard protocols look for a wide variety of compounds of concern for racing integrity, such as anabolic steroids, beta2 (b2)agonists, selective androgen receptor modulators, erythropoietin, and other similar doping agents. All post-race samples were tested for cobalt. Routine testing in California exceeds national graded stakes testing standards. The Maddy Laboratory is accredited by the Racing Medication and Testing Consortium and the only laboratory in the Western Hemisphere certified by the International Federation of Horseracing Authorities.

The Maddy Laboratory cleared TCO2 samples on 148 horses that competed in 14 Breeders' Cup races along with 69 horses that competed in other races on the two Breeders' Cup cards. The large fields were popular with the public, as the total all-sources common-pool handle for the two-day world championships was $182,908,409, a new record for the two-day event.

There were no equine fatalities in the races nor any observable injuries to the horses. Carl Woods, the assistant starter who was injured at the starting gate on November 5, informed the CHRB that he is fine and back to work.

Jockeys rode under extremely restrictive rules governing the use of the riding crop. Three jockeys (Florent Geroux, E. T. Baird, and Tom Eaves) violated those rules and received fines totaling $11,000. Two of those fines were $5,000, possibly the highest in North America for whipping violations. All jockeys were advised by the stewards prior to the races that the crop rules would be strictly enforced and that fines would be elevated.

All Breeders' Cup horses competed without the administration of furosemide, or Lasix.

All Breeders’ Cup Tests Come Back Clean

All samples collected from 2021 Breeders' Cup horses have been cleared by the Kenneth L. Maddy Equine Analytical Chemistry Laboratory at the University of California, Davis.

All horses competing in Breeders' Cup races this past weekend at Del Mar were tested for TCO2 levels in blood. Post-race testing was performed for prohibited drugs on the first four finishers in all Breeders' Cup races and any additional random horses selected by the stewards consistent with California Horse Racing Board protocol. Post-race testing was done on both blood and urine samples. The GI Breeders' Cup Classic was won by Knicks Go (Paynter).

NAARV Calls for Revision of Medication Thresholds

In a release authored by its Executive Director Erica Minks, the North American Association of Racetrack Veterinarians (NAARV) is calling on the racing industry to adopt “rational thresholds” as they relate to post-race testing of racehorses. The release comes in the ongoing aftermath of Medina Spirit's positive test for betamethasone, which registered 21 picograms per milliliter.

“The North American Association of Racetrack Veterinarians has advocated for rational and common-sense thresholds for therapeutic medications in racing horses since its inception in 2014,” the release says. “As recently as December 2020, NAARV, with the support of both the Horsemen's Benevolent & Protective Association and United States Trotting Association, proposed a 100 pg/mL threshold (more than four times the level identified in Medina Spirit) for betamethasone. That's because research has recently been published demonstrating that positives below this level can readily be achieved with the simple exposure of the horse to urine from a treated horse, or the many betamethasone-containing creams and sprays for topical use that are available for both humans and horses.

“There is no evidence that this level of betamethasone has any effect on horse performance, nor on the masking of pain. Picogram thresholds and zero-tolerance for therapeutic medications in this current environment, where a thousandth of a picogram can be detected by state-of-the-art testing equipment, are not relevant.

“It is time for the racing industry to follow the science and adopt rational thresholds. By focusing on insignificant levels of therapeutic medications, the regulators of our sport are depriving the industry of appropriate veterinary decision making, alarming the public and fans of horse racing, and creating an erroneous impression of dishonesty and exploitation. This must stop before it collapses the industry. It must stop for the sake of the horse.”
