Kraft Foods Group isn’t stringing anyone along — pun intended, obviously — with a voluntary recall of certain varieties of Kraft and Polly-O String Cheese and String Cheese Twists. The problem is that no one likes eating processed cheese that’s past its time, and about 735,000 cases might be doing just that.

The company announced the recall in the last few days, saying that the aforementioned products might be spoiled before the clock strikes midnight on their “Best When Used By” code dates. That could cause the products to become discolored as well, which does not usually have an appetizing effect.

According to the FDA and Kraft, the affected products all have code dates from October 25, 2013 through February 11, 2014, but no one in Canada got one of the bad cases, just the U.S. customers.

The best by date is on the back of multi-content packages toward the bottom, or on the bottom of the front of the package for individually sold products. The recall was prompted by reports of premature spoilage and has led Kraft to stop the production and distribution of products from a facility in New York state while the investigation continues.

Got bad cheese? Don’t eat it — return it to the store where you purchased it for an exchange or full refund.
