Two government-friendly parties yesterday vowed to vote to block an amendment proposed by a Democratic Party legislator to a controversial new food-labelling law. Fred Li Wah-ming said he would move the amendment in the Legislative Council on Wednesday seeking to remove exemptions the government has written into the bill for products carrying health claims. Mr Li said he would boycott such products if the law was passed in its present form. But the Democratic Alliance for the Betterment and Progress of Hong Kong and the Liberal Party said they were satisfied with the compromise proposal put forward by the government and would vote against the amendment. As first proposed, the labelling law would have exempted only products selling fewer than 30,000 units a year that did not carry nutritional claims such as 'low-fat' or 'zero trans-fat'. The government extended this to low-volume products that did carry health claims after retailers said up to 15,000 lines of food would be affected if all so-called 'health' products had to carry labels detailing ingredients. Mr Li said the flexibility given to those products was unacceptable because the practice would create a loophole in the law, undermining protection of consumers' health. 'The compromise is a political one and it goes against the purpose of the legislation by compromising the consumers' right to being informed fully about the ingredients,' he said. Under the proposed regulation, packaged food will have to carry labels detailing total energy and seven elements: protein, carbohydrates, total fat, saturated fat, trans-fatty acids, sodium and sugar. Liberal Party legislator Vincent Fang Kang, who represents the wholesale and retailing sectors, said consumers would be the losers if Mr Li's amendment was passed because it could mean many of the health foods could not be imported. 'We wholeheartedly care about people's health, which is always our top priority,' Mr Fang said. 'But if we make a law that is so strict that food deemed healthy overseas is banned in Hong Kong, is it what we want to do for people's health?' Citing low-sodium chips, Mr Fang said: 'In the US and Canada, they accept a level of 3g. But Hong Kong wants to set the limit at 2.5g. If we disallow the import of such low-sodium chips, our consumers will be forced to buy chips with a higher sodium level.' DAB legislator Tam Yiu-chung echoed Mr Fang's views. 'The government's compromise proposal is not the best. But if it is generally accepted by the community, we should try it first ... we can review it later.'
