Kraft Foods Group, Inc., is voluntarily recalling some of its Kraft and Polly-O string cheese because it may spoil and change color before the expiration date on the packages.
The company said about 735,000 cases of the affected products were shipped to customers in the United States.
They have "Best When Used By" dates from October 25 through February 11.
Kraft said it issued the recall after receiving several reports from consumers about cheese going bad.
The company has stopped making and distributing the affected products.
The products were made in a plant in Campbell, New York.
Consumers should not eat the recalled products and should return it for an exchange or refund.
