Fish, sweet potato eaters cautioned
Food authorities yesterday cautioned people against eating sweet potatoes and a popular fish that might be contaminated with illegal food colouring.
This came after Mongkok retailers surrendered 500kg of sweet potatoes following a complaint to the Food and Environmental Hygiene Department on Wednesday.
Another 67kg was surrendered from a stall at the Cheung Sha Wan wholesale market.
Most tests on sweet potato samples showed the colouring was a natural substance, the department said last night, but it advised consumers to be wary of 'abnormally intense colour'.
Tests also began on samples of yellow croaker fish for food colouring, but no stocks had been confiscated in the past three days, the department said. Both the sweet potatoes and fish are believed to have come from the mainland.
'If you buy fish and you find that the colour is extraordinary and after handling it the colour stays in your hands, then you have reason to believe the fish is treated with colouring matter,' a department spokesman said.
