Section 17. Any person or persons who shall in any of said cities engage in or carry on the sale, exchange, or traffic in milk, shall have the carriage or vehicle from which the same is vended, conspicuously marked with his, her or their names, also designating the locality from which said milk is obtained or where produced, and for every neglect of such marking, the person or persons so neglecting shall be subject to a fine not exceeding ten dollars. For marking wagons or vehicles so as to convey the idea that said milk is procured from or produced in a different locality than it really is, the person or person so offending shall be subject to a fine not exceeding fifty dollars. The addition of water or of ice to milk, is hereby declared an adulteration, and any milk obtained from animals fed on distillery waste or any substance in a state or putrefaction, is hereby declared to be impure and unwholesome.
