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.”
