S.D. Codified Laws § 57A-9-609.2
Any person who for himself, or through an agent, sells livestock through a livestock auction agency, as defined in chapter 40-15 and § 301 of the Packers and Stockyards Act (7 USC 201), or who so sells grain through a public grain warehouse, or through a public terminal grain warehouse, or a grain dealer as defined in chapters 49-43, 49-44, and 49-45 respectively, without notifying the livestock auction agency or the grain warehouse or grain dealer of a security interest in such farm products, and with intent to defraud, is guilty of farm products fraud. The failure of the seller to give written notice of a security interest in the farm products prior to the date of the sale by the livestock auction agency, or the grain warehouse, or grain dealer, is prima facie evidence of intent to defraud.
A violation of this section is a Class 1 misdemeanor.
