Organic Tofu Recall, Listeria Discovered

San Francisco - As a precaution, a San Francisco tofu company has expanded a recall of their organic tofu after a bacteria called  Listeria monocytogenes was discovered in three of 29 products and 3 plant swabs. The organism can cause serious and sometimes fatal infections in young children, frail or elderly people and others with weakened immune systems. The company, Quong Hop & Co. of South San Francisco, California issued the recall voluntarily. No illnesses have been reported to date in connection with this problem.

The extended recall is being done because these items have the potential to be contaminated with Listeria monocytogenes,  Although healthy individuals may suffer only short term symptoms such as high fever, sever headache, stiffness, abdominal pain and diarrhea, Listeria infection in severe cases can cause miscarriages and still births among pregnant women.



Quong Hop & Co. of South San Francisco, California is expanding their recall of tofu to include the following products in the following sizes and code dates:


  • All varieties and sizes of SOY DELI TOFU BAKED TOFU all Dates through 1/28/2008

  • All varieties of SOY DELI TOFU BURGERS all dates through 1/28/2008

  • SOY DELI 12oz and 8oz VACUUM PACK WHITE TOFU all dates through 1/28/2008

  • All SOY DELI HAWAIIAN TOFU and MESQUITE SMOKED TOFU all dates through 1/28/2008

  • All SOY DELI and QUONG HOP WATER PACK TOFU dates through 11/28/2007

  • ALL varieties and sizes SOY DELI BULK WHITE TOFU all dates through 11/28/2007

  • All varieties of SOY DELI PASTA all dates through 11/28/2007

  • SOY DELI 30oz VACUUM PACK NIGARI FIRM WHITE TOFU all dates through 11/28/2007

The recalled "SOY DELI" and "QUONG HOP" brand products are distributed in the Midwest and West coast through supermarkets and natural food stores.


This expanded recall reflects product currently in the market. No additional cases of bacteria have been reported. This is a precaution being taken to help ensure product safety. The date code can be found on the front panel of all the aforementioned products printed in blue ink. 

The potential for contamination was noted after a routine test by Washington State Department of Agriculture's Food Safety Program revealed the presence of Listeria monocytogenes in a 12 OZ vacuum pack package of "SOY DELI FIRM ORGANIC NIGARI TOFU" Further testing in two sample lots confirmed that the 12oz , 30 oz and Bulk tofu did contain traces of bacteria The company is voluntarily recalling all products produced during the same time period as the sampled product to ensure customer safety.

The Company has been in operation for over 100 years and this is our first detection of Listeria. Our primary concern is our consumers safety.

Consumers who have purchased the recalled products are urged to return them to the place of purchase for a full refund. Consumers with questions may contact the company at 650-553-9900 ext 22.
