Chobani Issues All-Clear After Yogurt Recall

A week ago, Chobani said that it was investigating its production chain after reports of packages swelling or bloating. Customers' claims of illness led the company to escalate its response on Thursday, when it announced, "To be extra cautious, we have moved from a voluntary withdrawal to a voluntary recall."

At the time of the recall, Chobani said it had successfully pulled more than 95 percent of the products in question. They were made at the company's new facility in Twin Falls, Idaho, which opened last December.

Chobani asked customers who bought containers showing the manufacturing code 16-012 and a "best by" date between Sept. 11 and Oct. 7 to dispose of the yogurt and get in touch for a refund.

The mold can cause spoilage in yogurt products by leading to swelling and bloating, Chobani says. To explain more about it, the company quotes Cornell University's Randy Worobo, a professor of food science:

"This mold should not pose a health risk to most consumers. Very rarely, it can act as an opportunistic pathogen, but not through food and usually only for people with compromised immune systems through inhalation. The organism is regularly used for the production of natural flavor compounds that are widely used in the food industry."

Cornell says that Worobo was not paid to speak about the mold and that he offered his comments as a food expert, not as someone who had tested the products in questions, the AP reports.
