NORTHVILLE, Mich. (AP) — A Michigan dairy is conducting a voluntary recall of some of its products due to the failure of equipment used to verify proper pasteurization during processing.

The state Department of Agriculture and Rural Development announced Thursday that Northville-based Guernsey Farms Dairy‘s recall includes five products produced at different times. The state says they were primarily distributed in southeastern Michigan.

No illnesses have been reported.

Products include: skim milk, gallon size, with code date Oct. 20; egg nog, quarts and half-gallons, with code date Oct. 21; half-percent milk, half-gallon size, with code date Oct. 11; butter pecan ice cream, 48-ounce, with product code 27116; and French vanilla ice cream, 48-ounce, with product code 27016.

Consumers should dispose of the recalled products or return them to the place of purchase for replacement.
