For the purpose of preventing fraud and deception in the manufacture, use, sale, and transportation of food, or for the purpose of protecting and preserving the public health, it shall be the duty of the commissioner to fix, adopt, and publish, from time to time, by rulings, in writing, definitions and standards of quality, purity, identity, composition, analysis, content and strength of articles of food, for which no definitions and standards are prescribed by law, and such definitions and standards so fixed, adopted, and published by the commissioner shall be the lawful definitions and standards thereof before all courts; provided that when definitions and standards have been or may be fixed by the secretary of the Department of Agriculture, or the secretary of the Department of Health and Human Services of the United States, except in cases where definitions or standards otherwise are prescribed by law, they may be accepted by the commissioner and if accepted, published as definitions or standards for Minnesota. All definitions and standards promulgated and adopted by the commissioner shall be done in the manner provided by law. Until such definitions and standards are promulgated and adopted in the manner stated, the definitions and standards heretofore prescribed by law or promulgated and adopted by the commissioner shall remain in full force and effect, except as otherwise prescribed by law. Any person who shall manufacture, use, sell, transport, package, offer for sale or transportation, or have in possession with the intent to sell, package, repackage, offer for sale or transportation, or use, or transport, any article of food, which does not conform to such definitions or standards so fixed, adopted, and published, shall be guilty of a misdemeanor.
