Organic yogurt manufacturer Stonyfield is voluntarily extending the recall of its YoBaby Peach/Pear yogurt to 271 additional stores in six western states.

Recalled yogurts were potentially contaminated with the coliform Klebsiella pneumoniae.

The recall includes an additional 1,344 packs of yogurt shipped primarily to Safeway and Fred Meyer stores in Oregon, Washington, Montana, Idaho, Alaska and northern California.

The recall includes the 4-ounce 6-pack cubs with a code date of June 5, 2014. According to the company, most yogurts were pulled from shelves, but there is a chance some were purchased.

In April, the company voluntarily recalled 188 6-packs of yogurt from Target stores in the southeast and some Mid-Atlantic Walmart stores because of the same potential contamination.
