(b) The detection and confirmation by the Commission's Testing Laboratory of a prohibited drug, medication, chemical, substance or any other foreign substance in a test sample of a horse shall be prima facie evidence that the prohibited drug, medication, chemical, substance or other foreign substance was administered to the horse and carried in the body of the horse while participating in a race. This finding shall also be taken as prima facie evidence that the trainer and the trainer's agents responsible for the care, custody or control of the horse has been negligent in the handling or care of the horse.

(c) The determination by the Standardbred or Thoroughbred Bureau Directors, based upon a finding by the Commission Testing Laboratory of a foreign substance or an approved therapeutic substance above the established level in violation of this chapter, may be declared an overage or positive test and may result in the horse being disqualified from purse money or other awards, except for purposes of pari-mutuel wagering, which shall be in no way affected.
