With the support of the Quarter Racing Owners of Ontario Inc (QROOI), the Ontario Racing Commission (ORC) has launched an initiative to conduct random out-of-competition testing for the presence of clenbuterol in quarter horses, commencing July 1, 2011. Clenbuterol is a bronchial dilator and is sold under the name Ventipulmin as an injectable suspension and oral syrup.

In the course of the out-of-competition testing, ORC investigators will enquire as to the use of clenbuterol. The investigators will then examine the records of the trainer and veterinarian to confirm the veterinarian’s examination of the animal, the prescription for the drug, as well as the time and dosage. These records are to be readily accessible for inspection by ORC investigators. For example, trainers should keep the records in the barn where the horse is stabled.

Trainers are reminded that under the Rules of Racing (TB 15.09.01-f) they shall maintain records relating to the particulars of any medications administered to horses in their care. Veterinarians are also reminded that under the rules (TB 27.14), the records maintained and kept by a veterinarian shall include the name of the horse, the names of the owner and trainer, the date of the administration or prescription of the drug, substance or medication, and its nature.

The ORC urges the full cooperation of trainers, veterinarians and members of the quarter horse racing community in this initiative.
