Chang Farm, Whatley, Mass., recalled soy bean sprouts with the sell-by date of July 17, 2009 because of the possible presence of listeria contamination.

According to a release from the company, the sprouts are in 10-pound bulk bags and 12-ounce plastic bags, labeled under the Chang Farm brand as Soy Sprouts. The sprouts, recalled July 14,  were distributed to retail stores and wholesalers throughout Massachusetts, Connecticut, New York and New Jersey.

The company asked that retailers and wholesalers who have the product remove it from their shelves and distribution centers. Consumers should discard the sprouts, or return them to the place of purchase for a full refund.
