Reason For Issuing Alert

The CFS collected the above-mentioned sample from a supermarket in North Point for testing under its routine Food Surveillance Programme. The test result showed that the sample contained sulphur dioxide. Although the sulphur dioxide level is below the maximum permitted level under the Preservatives in Food Regulation (Cap. 132BD), the functional class and the 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 of the irregularities and instructed it to stop sale and remove from shelves the affected batch of the product. The distributor concerned 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.

Advice to the Trade

Stop using or selling the affected batch of the product immediately if they possess it.

Advice to Consumers

Should not consume the affected batch of the product.
