Starbucks said it’s voluntarily recalling some 1,700 bottles of Evolution Fresh juice sold at grocery stores in California and Nevada after the company detected a potential problem.

The Seattle company said Friday it had found a small number of swollen Organic Sweet Greens and Ginger juice bottles with “best by” dates of March 2, and so proceeded to recall bottles sold in about 120 grocery stores in the two states.

On Monday a spokesman said that a preliminary investigation confirmed that “this was an isolated incident and a product quality issue, not a food safety issue,” but that a more comprehensive inquiry is still underway.

Starbucks said it received no complaints nor alerts of illnesses related to the product.

The company said that Organic Sweet Greens and Ginger juices with other “best by” dates, as well as other products, are not part of the recall. The product was not sold at Starbucks retail stores, the company said.

The recalled bottles, which it began selling on Jan. 18, represent less than half of one percent of Evolution Fresh’s production.

Starbucks bought Evolution Fresh in 2011 to diversify beyond coffee and establish a bigger presence in grocery aisles.
