Kraft Foods is recalling types of their Kraft and Polly-O string cheese products.
The products, which include varieties of Kraft and Polly-O string cheese and string cheese twists, may spoil before their "best when used by" code dates, leading to product discoloration.
Some 735,000 cases of the affected products were shipped across the United States.
All of the items have code dates from Oct. 25, 2013 through Feb. 11, 2014.
Kraft issued the recall after receiving consumer complaints about premature spoilage.
Consumers can return the items to the store where purchased and receive a full refund.
