Soil contaminants dredged from the Kalamazoo River and grown at a Caledonia-area farm in northeast Allegan County have been determined to be contaminated and unfit for sale to the public

Officials with the Michigan Agricultural Department said more than 90,000 bushels of  soybeans, which were made into food, must be destroyed because some of the crop was grown on land that had sediment from the Kalamazoo River Superfund site.

Soybeans, high in protein, customarity are turned into animal feed, but can also be used to make oil and food products for human consumption as well as biodiesel fuel, according to a Associated Press story about the decision.

The soybeans, locked up under state order in Hamilton, were sold for $1,300 to CHS, a global Minnesota-based farm cooperative with operations in Michigan, which later filed a lawsuit against the farm for an unspecified amount of compensation.
