Millions of packages of cheese produced at a Corning-area plant may spoil early, so a recall is underway.

Kraft Foods is recalling some cheese items manufactured at its factory in Campbell. The affected products have code dates from October 25, 2013 through February 11, 2014.

According to the company, spoilage has been occurring before the "best when used by" date on the packages of Kraft and Polly-O string cheese and cheese twists.

A Kraft spokeswoman told WNBF News that production of the affected products at the Campbell facility has stopped as the company tries to determine what caused the problem.

The spokeswoman said Kraft does not know what went wrong with the production of the cheese.

About 400 people work at the plant. Most of them are still working on other activities at the site.

About 735,000 cases of the potentially-bad cheese were shipped across the United States.

The company reported it has received "several reports" from consumers of premature spoilage.

People who have any of the affected products should not eat it. They should return it to where they bought it for an exchange or a refund.

Kraft Foods may be reached at 800.816.9432 between 9 a.m. and 6 p.m.

The Food Bank of the Southern Tier says food pantries and mobile food sites in Broome, Tioga and four other area counties may have distributed some of the recalled cheese over the past month. People who received any of the affected cheese are being advised to throw it away.
