Detention enclosure

Each association shall provide and maintain a designated detention area or enclosure for use by the commission in securing from horses that have run a race, samples of hair, urine, saliva, blood, or other bodily substances or tissues for chemical analysis. The enclosure must include a wash rack, commission veterinarian office, a walking ring, and a sufficient number of stalls each equipped with a window sufficiently large to allow the taking of the samples to be witnessed from outside the stall.
