Dr. Mark Horton, director of the California Department of Public Health, today warned consumers, particularly infants, young children and pregnant women, not to eat the following Soy Deli brand tofu products manufactured by Quong Hop and Co. of South San Francisco because they may be contaminated with Listeria monocytogenes, a dangerous bacteria that may cause serious health problems:

  • All varieties and sizes of Soy Deli brand tofu (date code Dec. 17, 2007).
  • 12-ounce Soy Deli brand Water Pack Tofu (date code Sep. 23, 2007).
  • 30-ounce Soy Deli brand Nigari Tofu (date code Sep. 23, 2007).
  • 16-ounce Quong Hop brand Water Pack Tofu (date code Sep. 23, 2007).
  • 12-ounce Soy Deli brand Water Pack Tofu (date code Oct. 9, 2007).
  • 30-ounce Soy Deli brand Nigari Tofu (date code Oct. 17, 2007).

These recalled products were distributed to supermarkets and natural food stores on the West Coast and throughout the Midwest.  No illnesses have been reported in association with these products.  

The recall was initiated after routine surveillance sampling conducted by the Washington State Department of Agriculture’s Food Safety Program detected Listeria monocytogenes in a 12-ounce package of “Soy Deli Firm Organic Nigari Tofu.”   The recall was expanded to include all products that could have been produced during the same time period as the tested sample.

Listeria monocytogenes is a bacterial organism that can cause serious and sometimes fatal infections in newborns, the elderly and persons with weakened immune systems.  Although healthy individuals may suffer only short-term symptoms such as fever, headache, stiffness, nausea, abdominal pain and diarrhea, Listeria infection can cause miscarriages and stillbirths among pregnant women.  Consumers with any of these symptoms should call their physician. 
Consumers who purchased these products should immediately discard them or return them to the point of purchase.  Consumers with questions can call Quong Hop at 1-650-553-9900.
