Reason For Issuing Alert
  • The CFS collected the above-mentioned sample from a supermarket in Chai Wan for testing under its routine Food Surveillance Programme. The test result showed that the sample contained sulphur dioxide. However, the functional class and name of the additive were not declared on the food label of the sample.
  • Sulphur dioxide is a preservative which can be used in a variety of foods including dried vegetables, dried fruits, pickled vegetables and salted fish products. Sulphur dioxide is water soluble, and most of it can be removed through washing and cooking. However, susceptible individuals who are allergic to this preservative may experience breathing difficulties, headache and nausea after consumption.
Action Taken by the Centre for Food Safety
  • The CFS has informed the vendor concerned and the sole agent of the irregularity, and instructed them to stop sale and remove from shelves the affected batch of product. The sole agent has initiated a recall according to the CFS' instructions.
  • The CFS will alert the trade, continue to follow up on the incident and take appropriate action. Investigation is ongoing.
