Two local importers of livestock and poultry are stockpiling meat to cope with a possible Y2K bug breakdown over New Year. Ng Fung Hong, the major importer of livestock from the mainland, said it would keep double the normal stock at its Shenzhen farm. By Friday, the stock will stand at 30,000 pigs and 2,800 cattle, which could cater for Hong Kong's needs for up to a week. 'The system might still breakdown even though tests indicate it is Y2K compliant,' a spokesman said. Poultry importer Guangnan would raise its imports of chicken from the mainland by 40 per cent on Friday, the Agriculture and Fisheries Department said. Officials have reminded major importers to keep extra stock. They said local levels of livestock, poultry and fruit and vegetables could last for at least two days of normal consumption.
