Chobani Pulls 'Fizzy,' 'Swelling' Yogurt Off Shelves

Chobani is pulling some of its Greek yogurt from supermarket shelves after hearing of "swelling or bloating" in cups.

The company said it has investigated and found a type of mold commonly found in dairy that may be to blame.

On Tuesday, Chobani was responding to people who were complaining about their yogurt cups on Twitter. One person described her cup as "unnervingly fizzy," another said the cups were like "yogurt soup" and another said it tasted like "wine."

Yet another person said the strawberry flavor they bought tasted "really old."

A representative for Kroger, which operates Ralphs supermarkets, said Chobani issued a product withdrawal Friday. "It was not a food safety issue," Kroger spokesman Keith Dailey said in an email.

Chobani said the affected product came from its Idaho facility and represents less than 5 percent of its total production. The company has been working with retailers to remove and replace containers with the code 16-012 and expiration dates Sept. 11 to Oct. 7.

Chobani, which is based in New Berlin, N.Y., did not say how many of its cups or what varieties were affected. The effort was voluntary and it is not issuing a formal recall.

Chobani, which says it uses only high-quality, natural ingredients, has grown rapidly since it was founded in 2005.

Greek yogurt in general has surged in popularity as well, with fans saying they prefer its thicker consistency and relatively higher protein content when compared with the sweeter yogurt varieties that have long been sold in American supermarkets.

Chobani says customers with the affected code dates should contact its customer service team at care@chobani.com to get replacement products.
