California Horse Racing Board

The California Horse Racing Board held its monthly meeting in Arcadia on February 25.

The California Horse Racing Board on February 25 approved a rule prohibiting the presence of clenbuterol in an American Quarter Horse test sample.

The rule requires that any horse treated with Clenbuterol be placed on the Veterinarian’s List and prohibited from racing until the horse tests clear.

Also at the CHRB meeting, the board’s Legislative, Legal, and Regulations Committee reported on its February 24 meeting, during which the pilot microchip program and illegal match races were discussed. CHRB investigators will work with local law enforcement agencies to identify licensees who may be participating in illegal match races, which typically take place at private ranches.

The CHRB also amended a proposal that would alter the state's riding rules. The riding rules change has been in the works since March of 2014 and the CHRB sent it out for public comment again. The change to the proposal cut down a "multiple infraction window" for jockeys—which would increase penalties for multiple offenses during that time—from 90 to 60 days and also eliminated language that disqualifications could only occur if the infraction caused a horse to lose a placing "according to the distribution of the purse or the order of finish in a trial heat."

The proposal, as currently composed, clarifies the definition of "interference" as "bumping, impeding, forcing or floating in or out, or otherwise causing any other horse to lose stride, ground, momentum or position."
