SAN FRANCISCO Three organic food companies that use spinach in their food have recalled hundreds of thousands of items over listeria concerns.

Organic food company Amys Kitchen has voluntarily recalled about 74,000 cases of frozen and prepackaged products containing spinach.

It comes after one of Amys suppliers issued a recall notice saying the Petaluma-based company may have received organic spinach possibly tainted with the bacteria that causes listeria.

U.S. Food and Drug Administration officials are aware of the recall.

The disease can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems.

Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, listeria infection can cause miscarriages and stillbirths among pregnant women

The company reports it has not had any complaints of illnesses from the products being recalled in the United States and Canada.

The recalled items include vegetable lasagna, tofu vegetable lasagna, garden vegetable lasagna, tofu scramble, enchilada verde meal, spinach pizza, brown rice and vegetables owl, stuffed pasta shells bowl, gluten-free tofu scramble and the breakfast wrap.

Rochester-based Wegmans Food Markets is recalling roughly 12,540 packages of Wegmans organic spinach due to possible contamination with listeria. The 12-ounce product was sold in the frozen food department of the companys 85 stores in New York, Pennsylvania, New Jersey, Virginia, Maryland, and Massachusetts between Jan. 27, and March 21. This product is supplied to Wegmans by Twin City Foods in Stanwood, Washington. A representative from that company said he would have comment later Tuesday.

On Monday, Carmel Food Group issued a voluntary recall of certain Rising Moon Organics frozen ravioli items over the same concern.
