NORTHFIELD, Ill. (AP) -- Kraft Foods Group is recalling some cottage cheese products, company officials announced Saturday.

Some ingredients used in Knudsen Cottage Cheese, Breakstone's Cottage Cheese, Simply Kraft Cottage Cheese and Daily Chef Cottage Cheese weren't stored in accordance with proper temperature standards at a Tulare manufacturing facility, they said.

While unlikely, the failure to properly store ingredients might have created conditions that could lead to food-borne illness, Kraft said. The company voluntarily recalled 1.2 million cases of the cottage cheese.

The products, with a coded date between May 9 and July 23 stamped on them, were only shipped to stores in the United States. The codes can be found on the cup bottoms or atop the packages.

Anyone who purchased these products should not eat them. They can be returned to the stores where they were bought for exchanges or full refunds.
