A $71 million fraud case in South Dakota is the latest blow to the organic supply chain.
Federal prosecutors in February accused Kent Duane Anderson, a Rapid City, S.D., businessman, with passing off conventional grain and seed as organic for more than five years.
Anderson pleaded not guilty to charges of wire fraud and money laundering.
The case is the second large-scale organic fraud case in the Midwest to attract federal prosecution in less than a year, and comes amid ongoing concern over fraudulent organic imports.
