Reason For Issuing Alert

-   The Centre for Food Safety (CFS) collected the above-mentioned preserved mustard greens sample from a retail outlet in Wan Chai for testing under its routine Food Surveillance Programme. The test result showed that the sample contained sulphur dioxide but the functional class and the name of the additive were not declared on the food label of the sample concerned.

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.
