A horse from the barn of grade 1-winning trainer Phil Serpe has tested positive for the bronchodilator clenbuterol. The Horseracing Integrity and Welfare Unit noted that the drug was found in Fast Kimmie ‘s system following the filly’s victory in a $30,000 claiming race Aug. 10 at Saratoga Race Course.

Fast Kimmie, won the mile race by a half-length. She was not claimed in the race.

Clenbuterol is officially listed as a controlled substance and can be prescribed by a veterinarian since it is therapeutically used to clear up congestion in horses. However, the drug is highly controlled since studies show the substance possesses steroidal properties. Once the horse has been treated with clenbuterol, it must remain on the vet’s list for 21 days and be cleared of the substance in order for the horse to be eligible to breeze or race. If clenbuterol is detected in a postrace test after no treatment history is provided, the medication is treated as a banned substance and considered an anti-doping violation.

Serpe has been provisionally suspended until HIWU, the Arbitral Body, and Internal Adjudication Panel have reviewed his case so that a final verdict can be determined. Trainers found using banned substances face up to two-year suspension, fines, and the forfeiture of the race purse.

A trainer since 1984, Serpe has saddled the winners of 1,080 races for earnings of $34,699,599.
