(1) The commission may require a postmortem examination of any horse that is injured on the grounds of a racing association during its scheduled race meet and training periods, while the horse is in training or in competition and that subsequently expires or is destroyed, or any horse that expires while housed on the grounds. In proceeding with a postmortem examination the commission or its designee will coordinate with the trainer and/or owner to determine and address any insurance requirements.

(2) Trainers and owners must cooperate with such action as a condition of licensure.

(3) An official veterinarian may take possession of the horse upon death for postmortem examination. An official veterinarian may submit blood, urine, other bodily fluid specimens or other tissue specimens collected during a postmortem examination for analysis. Upon completion of the postmortem examination, the remains may be returned to the owner or disposed of at the owner's option.

(4) The presence of a prohibited substance in a specimen collected during the postmortem examination may constitute a violation of these rules.

(5) The cost of commission-ordered postmortem examinations, testing and disposal will be borne by the commission.
