(a) The commissioner, with the approval of the board, is authorized to promulgate such rules and regulations for commercial feeds and pet foods as are specifically authorized in this chapter and such other reasonable rules and regulations as may be necessary for the efficient enforcement of this chapter. In the interest of uniformity, the commissioner shall, by regulations, adopt, unless he determines that they are inconsistent with the provisions of this chapter or are not appropriate to conditions which exist in this state, the following:
(1) The official definitions of feed ingredients and official feed terms adopted by the Association of American Feed Control Officials and published in the official publication of that organization; and
(2) Any regulation promulgated pursuant to the authority of the Federal Food, Drug and Cosmetic Act (21 U.S.C. Section 301, et seq.); provided, that the commissioner, with the approval of the board, would have the authority under this chapter to promulgate such regulations.
(b) Before the issuance, amendment or repeal of any rule or regulation authorized by this chapter, the commissioner shall give adequate notice of the proposed regulation, amendment or notice to repeal an existing regulation in a manner reasonably calculated to give interested parties including all current licensees, adequate notice and shall afford all interested persons an opportunity to present their views thereon, orally or in writing, within a reasonable period of time. After consideration of all views presented by interested persons, the commissioner, with approval of the board, shall take appropriate action to adopt and promulgate the proposed rule or regulation or to amend or repeal an existing rule or regulation. The provisions of this subsection notwithstanding, if the commissioner, pursuant to the authority of this chapter, adopts the official definitions of feed ingredient or official feed terms as adopted by the Association of American Feed Control Officials, or regulations promulgated pursuant to the authority of the Federal Food, Drug and Cosmetic Act, any amendment or modification adopted by said association or by the Secretary of Health, Education and Welfare in the case of regulations promulgated pursuant to the Federal Food, Drug and Cosmetic Act, shall be adopted automatically under this chapter without regard to the publication of the notice required by this subsection, unless the commissioner, by order, specifically determines that said amendment or modification shall not be adopted.
