(2) Each retailer shall maintain on the premises fixtures and equipment in a clean and orderly condition. The premises shall be dry, well-ventilated, and have adequate lighting. (b) The board may, by regulation, impose any other minimum standards pertaining to the acquisition, storage, and maintenance of veterinary food-animal drugs, or other goods, or to the maintenance or condition of the licensed premises of any veterinary food-animal drug retailer as the board determines are reasonably necessary. (c) When, in the opinion of the board, a high standard of patient safety consistent with good animal safety and care in the case of an animal patient can be provided by the licensure of a veterinary food-animal drug retailer that does not meet all of the requirements for licensure as a veterinary food-animal drug retailer, the board may waive any licensing requirements.
