The dates are printed on the bottom surface of the cheese packages.

Consumers can also identify packages covered by the recall because the package will carry a code starting with 0 21000 and ending with suffixes 60464 7, 61526 1 or 63360 9.

Consumers who identify any of the products in question should not consume it and should return the packages to the place of purchase for exchange or refund, Northfield, Ill.-based.

Consumer could identify the varieties and package sizes involved in the recall on its website, the company said.
