The New Berlin, N.Y.-based company also would not say what caused the problem, but said it believes it has addressed the issue.
A representative for Kroger, the nation's largest traditional supermarket operator, said Chobani issued a product withdrawal Friday. "It was not a food safety issue," Kroger spokesman Keith Dailey said in an email.
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."
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.
The private company had an estimated $244 million in revenue in 2010, according to S&P Capital IQ.
Chobani says customers with the affected code dates should contact its customer service team at care(at)chobani.com to get replacement products.
