General Mills recalled a “limited quantity” of Cascadian Farm frozen green beans after a package of the product tested positive for listeria.

No illnesses have been reported, General Mills said. Listeria is a bacteria that causes listeriosis, a serious infection with symptoms including fever and gastrointestinal problems.

General Mills, based in suburban Minneapolis, said the voluntary recall involves 10-ounce bags of Cascadian Farm Cut Green Beans with either of two “better if used by dates” stamped on the package: “10APR2016” and “11APR2016.” The recalled products were distributed nationwide.

The company didn’t specify the quantity of the recall in pounds. Cascadian Farm is a major brand in the organic food market.

General Mills said the recall “is being issued as a precaution after one package of finished product tested positive for the presence of Listeria monocytogenes.” The recalled product was produced and packaged over two days in March 2014.
