Henry’s Farm Inc. of Woodford, VA has expanded the recall of its soybean sprouts to include natto soybean sprouts because they, too, may be contaminated with Listeria monocytogenes.

The initial recall was announced on April 27, 2012.

Test sampling by the state of Virginia’s Food Safety and Security Program returned positive results for Listeria.

No illnesses have been reported.

The recall is for:

– All clear 1.5 lb. plastic packages of Grown in Natural Spring Water Soybean Sprouts. The packages were not coded.

– All bulk (approximately 10 lb.) plastic bags of Soybean Sprouts. The packages were neither coded nor labeled.

– All clear 1 lb. plastic packages of Grown in Natural Spring Water Natto Soybean Sprouts. The packages were not coded.

The recalled sprouts were distributed to retail stores in Virginia, Maryland and Washington D.C.

According to state authorities, the lack of coding or other traceback labeling information has made it difficult to determine the quantity of sprouts distributed.

Individuals who have the recalled sprouts may return them to the place of purchase for a full refund.

For more information on the recall contact the company directly at 301-802-2996 or the Virginia Department of Agriculture and Consumer Services, Food Safety and Security Program at 804-786-3520.

Listeria can cause serious and sometimes fatal infections to individuals 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.
