USA Today has reported that according to The Jockey Club's Thoroughbred Safety Committee (TSC), retrospective testing of frozen samples will commence in April, 2009.

"The testing of these samples may result in positive test results, which can then be used as probable cause for the future collection of test samples from racehorses with the same owner, trainer or attending veterinarian," TSC chairman Stuart S. Janney III was quoted as saying.

The article states that Janney also said that an accumulation of positive test results by the same owner, trainer or attending veterinarian could be considered "aggravating circumstances" in the determinations of fines and suspensions.
