A tofu-producing company in San Francisco, Quong Hop & Co., has stated that it is recalling quite a few of its tofu products, many of which may be contaminated with Listeria monocytogenes, a food-borne disease that can affect kids, the elderly and others with weak immune systems.

At this time, no illnesses have been connected with the tofu products from the company, but the recall stands in place as a cautionary measure regardless.

The recall affects these Quong Hop & Co. products: the 30-ounce Soy Deli nigari tofu, the 12-ounce Soy Deli water packed tofu and the 16-ounce Quong Hop water packed tofu -- all with a date of September 23, 2007. Also, the recall was expanded after first being announced to include the 30-ounce Soy Deli nigari tofu coded Oct, 17, 2007, and the 12-ounce Soy Deli water packed tofu coded Oct. 9, 2007.
