Drug testing of horses running in the Breeders’ Cup at Santa Anita came back clear.
The California Horse Racing Board said testing was completed Tuesday after samples were delivered on Sunday to the Kenneth L. Maddy Equine Laboratory at UC Davis. Testing began within 24 hours of the Breeders’ Cup Classic, the final race of the two-day world championships that ended Saturday.
All horses underwent pre-race blood testing for total carbon dioxide levels, while post-race testing for prohibited drugs was done on the first four finishers in all of the 15 races, plus random horses selected by the stewards.
In addition to routine testing, 25 percent of all horses pre-entered in the Breeders’ Cup were randomly selected for out-of-competition testing, and those samples cleared before the event.
