Kraft is recalling 1.2 million cases of cottage cheese that could spoil prematurely and cause illness.

The recall, announced Saturday, includes the Knudsen, Breakstone, Simply Kraft and Daily Chef brands.

Ingredients used in nearly three-dozen cottage cheese products weren't properly stored in a California facility, Kraft Foods Group said.

Since the discovery, officials halted production of those products at that plant and began working to fix the issue, Kraft said.

Kraft called the recall precautionary. Spokesman Russ Dyer said the company was investigating one complaint of illness stemming from a batch of cheese that was not recalled and is now expired.

Many of the varieties recalled are tubs between 4 and 16 ounces. The products were stamped with dates between May 9 and July 23.

Each case includes between six and twelve tubs of cottage cheese.
