Reason For Issuing Alert

The CFS collected the above-mentioned sample from an online shop for testing under its routine Food Surveillance Programme. The test result showed that the sample contained methylmercury at a level of 0.8 milligram per kilogram, exceeding the legal limit of 0.5 mg per kg.

Methylmercury is the major form of mercury in fish. At high levels, mercury can affect foetal brain development, and affect vision, hearing, muscle co-ordination and memory in adults. Furthermore, as some international organisations such as the World Health Organization have pointed out, consuming predatory fish species is the main source of mercury intake for human beings. The report of the CFS's Total Diet Study has also pointed out that large fish or predatory fish species may contain high mercury levels (for example, tuna, alfonsino, shark, swordfish, marlin, orange roughy and king mackerel). Hence, groups particularly susceptible to the adverse effects of mercury, such as pregnant women, women planning a pregnancy and young children should opt for fish that are smaller in size for consumption and avoid consumption of the above-mentioned types of fish to minimise excessive exposure to metal contaminants in food.

Action Taken by the Centre for Food Safety

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. The importer concerned has initiated a recall according to the CFS's instructions. The CFS is also tracing the source of the product concerned.

The CFS will alert the trade to the incident, and continue to follow up and take appropriate action. An investigation is ongoing.

Advice to the Trade

Stop using or selling the affected batch of the product immediately if in possession.

Advice to Consumers

Not to consume the affected batch of the product.
