Kraft Food Groups has announced it is voluntary recalling 7,691 cases of Kraft American singles.

A supplier did not keep an ingredient used in the cheese at the proper temperature, according to Kraft.

There are four kinds of Kraft American Singles included. Products with best when used by dates of Feb. 20, 2015 and Feb. 21, 2015 are involved in the recall.

There have been no reports of illnesses from the recalled cheese, but Kraft is asking customers to return any tainted products to the store they bought it from for a full refund.
