Pig farming may have to be banned in the New Territories. The ban could be brought in as pollution levels at Deep Bay were up to 32 times the maximum recommended limit, partly due to livestock waste, the Advisory Committee on the Environment said. Pig farming may have to be stopped in the area as result, the committee's chairman Peter Wong Hong-chuen said. 'We were very sad to receive this report . . . even though our farms have been good and met high standards, those standards are not sufficient,' Mr Wong said. 'Can they continue to farm in the New Territories? It's a very tough decision,' he said. 'The easiest solution is to say 'no more farming' - but I don't think any of us want that.' Shenzhen authorities were already moving all farms on their side of the border to land further away from Deep Bay. But farmers' representatives said if they were moved, alternative farms would have to be provided. It would be difficult for pig farmers to find replacement farms if they were forced to move, said Fok Wui-ko, secretary of the Federation of Pig Raising Co-operative Societies, Hong Kong, Kowloon and New Territories Ltd. 'Facilities to reduce pollution at the farms have been installed since pollution control measures came into effect last year. Farmers have to invest $1 million on the facilities for every 3,000 pigs,' he said. 'Pollution problems have been reduced with these control measures.'
