(1) food, including all material, solid, liquid, or mixed, whether simple or compound, used or intended for consumption by human beings or domestic animals normally kept as household pets and all substances or ingredients to be added thereto for any purpose;

(2) napkins, facial tissues, toilet tissues, foil wrapping, plastic wrapping, paper toweling, disposable plates and cups;

(3) detergents, soaps and other cleansing agents; and

(4) non-prescription drugs, female hygiene products, and toiletries. c. "Package" shall mean any container or wrapper in which a consumer commodity is enclosed and offered or exposed for sale in a food store. d. "Package size" shall mean the physical dimensions of a container which encloses a consumer commodity. e. "Quantity" shall mean the net weight, volume, numerical count, area or linear measure, as appropriate, of the contents of a package. f. "Person" shall mean any individual, partnership, corporation, association, or firm. 2. Upon the petition of a substantial number of each group of manufacturers, packers, distributors, and retailers of any consumer commodity packaged or wrapped in advance of being offered or exposed for sale in a food store, the commissioner may hold a public hearing upon due notice to consider rules and regulations prescribing standard quantities or package sizes by which any such commodity shall be sold, or offered or exposed for sale in a food store. If the commissioner finds that the proposed standardization will reduce an undue proliferation of package sizes and facilitate the ability of consumers to make price comparisons, he may adopt and promulgate such rules and regulations with respect to such commodity unless a voluntary product standard has been established for such commodity pursuant to the federal fair packaging and labelling act. In addition to any such commodities, the commissioner may by rule and regulation, and without any public hearing, prescribe the existing standard quantities or package sizes for milk, cream, melloream, frozen desserts, flours and meals; thereafter the commissioner may prescribe standard quantities or package sizes for such commodities, whether or not a voluntary product standard has been established, without petition but shall hold a public hearing prior to the promulgation thereof. 3. No person shall sell, offer or expose for sale in a food store any consumer commodity for which the commissioner has prescribed, pursuant to subdivision two herein, a standardized quantity or package size except in a package or by a quantity which conforms to that prescribed by the commissioner.
