ALL pig and poultry farms in the territory could be wiped out if tough waste control licensing regulations are passed, operators claim. The Hong Kong Livestock Industry Association warned that should the proposals become law there would be a 10 per cent cut in the local supply. Chairman So Ying-kiu said: ''The requirements under the proposed legislation are too restrictive and give us no chance to continue our business. As a result, we'd all have to close for business.'' Farmers yesterday threatened to move their pigs and poultry to the streets or take violent action if the Government went ahead with the plan. ''We have no choice. If we cannot survive, we would like to die together with them [the Government]. We have prepared for the worst,'' he said. The Public Health Regulation (Animals and Birds) (Licensing of Livestock Keeping), studied by a Legco committee last week, requires farmers to treat their waste and meet the standards laid down by the Environmental Protection Department (EPD) before a licence is issued. But the farmers said it was not possible to meet the standards, because the requirements were too restrictive and unreasonable. More than 20 farmers yesterday met officials from the Planning, Environment and Lands Branch and the EPD and Agriculture and Fisheries Department (AFD) to vent their anger. The principal assistant secretary for the branch, William Hui Chi-wai, was quoted as saying the laws were aimed at controlling livestock waste, bringing it into line with environmental standards. But the association's vice-chairman, Ng Po-wing, said: ''They are making it difficult for us to operate. The legislation is a death penalty for us.'' Although the EPD and the AFD have tested various treatment methods to help farmers run their businesses and meet requirements, the farmers said they did not work. Mr Ng said: ''The Government did not take our views into account because they believed there will be no disruption of poultry supply if we cease our business.'' There are about 500 livestock farms in Hong Kong, supplying about 10 per cent of fresh meat for the local market. The association urged the Government to freeze the plan and work together with the farmers to come up with a livestock waste treatment method. ''At present, the only thing we can do is to lobby legislators to withdraw the bill,'' Mr Ng said.
