The supply of vegetables from the mainland picked up yesterday, but is still below import levels before new labelling measures came into effect this month. Vegetable Marketing Organisation general manager Edward Lai Kwok-yan said a total of 480 tonnes of vegetables were imported into the city yesterday. 'The amount was more than on Monday, but it was still 10 per cent less than the normal level,' Mr Lai said. In addition, the wholesale price was about 20 per cent higher than before the labelling steps came into effect. Farmers on the mainland have been asked to label their vegetables with the producers' detailed information in an effort to ensure better quality. Mr Lai predicted that the vegetable supply would return to normal in a week when the market adapted to the new system and the weather improved.
