Kraft Inc. has issued a voluntary recall on Oct. 25 for their Polly-O String Cheese and String Cheese Twists products after the company was made aware the food items may spoil before the "Best When Used By" code date.

According to the company's news release, about 735,000 cases of the bad batch of products were shipped across the United States only.

The cheese may spoil and lead to discoloration.  The tainted products all have code dates from Oct. 25, 2013 through Feb. 11, 2014.  For full list of products affected, click here.

Kraft released the following statement about the tainted products:

"As you may know, these are natural cheeses that contain no added preservatives, and it's not unusual for cheese to spoil over time.  But in this situation, we saw spoilage occurring before the "Best When Used By" Date.  

"That is not acceptable to us.  So we knew the right thing to do for our consumers was to voluntarily recall the affected product...Again, we're sorry that these products did not meet our standards and your expectations."

No other Kraft or Polly-O String Cheese or String Cheese Twists products -- or any other Kraft Foods or Polly-O products -- are being recalled.

Kraft is recalling the products after several reports from consumers complained of the product spoiling before its "Best When Used By" code date.  The tainted products were made in Campbell, NY.

"Kraft has ceased the production and distribution of the affected products from the relevant facility as the company continues its investigation to resolve the problem," the company said in their news release.  "Consumers who purchased any product listed above should not eat it.  They should return it to the store where purchased for an exchange or full refund."

Customers with questions about the recall are urged to email the company here or contact Kraft Foods Consumer Relations at 1-800-816-9432 between 9 am and 6 pm ET.
