Hall of Fame trainer Bob Baffert denied giving 2018 Triple Crown winning horse Justify a banned substance that caused a positive test prior to last year's Kentucky Derby and blamed the result on contaminated food.
Baffert said Thursday that he "unequivocally" rejects the implication he'd give Justify or any other horse scopolamine, which the colt tested positive for after winning the Santa Anita Derby in April 2018.
The New York Times reported Justify tested positive for the substance and that the California Horse Racing Board did not adequately investigate the matter. Justify was allowed to continue racing and won the Kentucky Derby, Preakness and Belmont Stakes to become the 13th Triple Crown winner in history.
"Damn shame this great horse, connections and me have to be put through all this," Baffert said in a text message to The Associated Press. "It was obvious environmental contamination. It's been a known problem in California."
California Horse Racing Board equine medical director Rick Arthur told the AP that the amount of scopolamine in Justify's blood was "minuscule" and that he recommended based on his findings that the case not be prosecuted. Scopolamine, also known as hyoscine, can be used to treat motion sickness in humans and in limited equine cases can relieve intestinal spasms, though it can be toxic to horses.
Scopolamine, which has been nationally downgraded from a class 3 to a class 4 level substance in horse racing, can come from jimson weed that grows wild in California. The Association of Racing Commissioners International's Uniform Classification of Foreign Substances guidelines say class 4 drugs "comprise primarily therapeutic medications routinely used in racehorses (that) may influence performance but generally have a more limited ability to do so."
Arthur said seven horses from four different trainers at Santa Anita were found to have some level of scopolamine or atropine in their systems during the period when Justify tested positive and he recommended that the two cases that crossed the threshold — Justify and another — be dismissed.
"It was a conclusion certainly of the executive staff that that was the appropriate and correct way to handle the case," said Arthur, who is equine medical director at the veterinary school at the University of California at Davis, and is assigned to but not paid by the California Horse Racing Board. "I'm the primary adviser on drug testing to the board, and my opinion is it would have no pharmacological effect."
