ST. PAUL (AP) - Minnesota Department of Agriculture regulators are investigating a Freeport area farmer for allegedly selling raw milk and other food products illegally.

According to a search warrant affidavit, Alvin Schlangen is believed to be selling raw milk from a south Minneapolis natural food warehouse and at a drop-off point in St. Paul. By law, raw milk can only be sold directly from farms.

Schlangen also has allegedly been selling other food without a license, according to the Agriculture Department.

Schlangen, an organic egg grower, says he is also the manager of a private food club that leases animals that provide fresh milk, cream and butter for its members. He says he did not break any laws.

Raw milk is unpasteurized, meaning it hasn't been heat-treated to kill pathogens.

According to the affidavit, Schlangen does not have his own dairy operation, but buys milk from dairy farmers and then resells it.
