Conn. Gen. Stat. § 21a-20
No person, by himself or agent, or otherwise, shall sell, expose for sale or have in his possession with intent to sell, any article which is produced by taking original packing stock or other butter, or both, melting the same so that the butter fat can be drawn off, and mixing such butter fat with skim milk, cream or other milk product, and rechurning the mixture, or by any similar process, and which is commonly known as process butter, unless he has the words "Renovated Butter" conspicuously stamped, labeled or marked, in a straight line in printed letters, not less than one-half inch in length of plain Gothic type, so that said words cannot be easily defaced, upon the top, side and bottom of every tub, firkin, box or package containing such article or compound. The seller at retail of such article or compound, which is not in the original package, shall, himself or by his agent, attach to each package sold and deliver therewith to the purchaser a label or wrapper bearing in a conspicuous place upon the outside of the package, the words "Renovated Butter" in printed letters not less than one-half inch in length in a straight line of plain Gothic type. Any person who violates any provision of this section shall be fined not less than ten dollars nor more than one hundred dollars. The manufacture, sale and use of renovated butter shall be regulated by the use of such signs as are prescribed for the use and sale of oleomargarine in sections 21a-16 and 21a-17, but the words "Renovated Butter" shall be substituted for the word "Oleomargarine".
