Prepackaged dried mushroom sample from China in breach of food labelling regulation


19th August 2022 – (Hong Kong) The Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department announced today that a sample of prepackaged dried mushroom was found to contain sulphur dioxide, a preservative which is allowed to be used in certain foods, but the name of the additive was not declared on the food label. Members of the public should not consume the affected batch of the product. The trade should also stop using or selling the affected batch of the product immediately if they possess it.

Product details are as follows:

Product name: (Not available in English)
Place of origin: China
Packer: (Not available in English)
Net weight: 500g
Best-before date: 30th November, 2023

 “The CFS collected the above-mentioned sample from a retail outlet in Kowloon Bay 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 name of the additive was not declared on the food label,” a CFS spokesman said.

“The CFS has informed the vendor concerned of the irregularity and instructed it to stop sale and remove from shelves the affected batch of the product. According to the CFS’s instructions, the packer concerned has initiated a recall on the affected batch of the product. Members of the public may call the packer’s hotline at 3188 3141 during office hours for enquiries about the recall of the product concerned. Prosecution will be instituted should there be sufficient evidence,” the spokesman added.

Sulphur dioxide is a commonly used preservative 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, headaches and nausea after consumption.

The spokesman reminded the food trade that the use of preservatives in food must comply with the Preservatives in Food Regulation (Cap. 132BD). Furthermore, the Food and Drugs (Composition and Labelling) Regulations (Cap. 132W) require that prepackaged food shall be legibly marked or labelled with a list of ingredients. The regulations also state that for all prepackaged food for sale in Hong Kong containing sulphite in a concentration of 10 ppm or more, the functional class of the sulphite and its name shall be specified in the list of ingredients. Offenders are liable to a maximum fine of $50,000 and six months’ imprisonment upon conviction.
