No person shall display for sale, outside of any building or within any building, store or other place, any beverage, food or food product, except in closed containers, so that they are protected from vermin, dust, dirt and other injurious contaminations; provided, that this shall not apply to fruits and vegetables which must be necessarily peeled, pared or cooked before used for human consumption. Displays must be elevated so that the bottom of the containers are not less than twenty-four inches above the surface of the sidewalks, steps or floors of the stores. Displays in watertight containers not less than twenty-four inches in height need not be elevated. Meat or any other article which may be used for human food without cooking, peeling, paring or shelling, or any food product not enveloped or protected from contamination by the touch shall not be handled by the public and food vendors shall make provision by screening, covering or glass cases, against such handling. Such screening, covering or glass cases shall be approved by the Health Officer or his authorized representative. The wrapping of food or foodstuff in anything but clean, fresh wrapping paper is prohibited. (1972 Code §8-10)
