Four officials were appointed yesterday in the final stage of the Government's shake-up of responsibility for food safety, hygiene, arts, sport and culture. Lily Yam Kwan Pui-ying becomes Secretary for Environment and Food, heading a new bureau overseeing food supply and safety, environmental hygiene and protection, conservation and agriculture and fisheries. Mrs Yam, 53, a former ICAC commissioner, is now head of a taskforce reorganising municipal services. She will be helped by Rita Lau Ng Wai-lan, 46, now head of the Urban Services Department, who becomes Director of Food and Environmental Hygiene. Paul Leung Sai-wah, 52, formerly trade representative in Tokyo, becomes the Director of Leisure and Cultural Services, taking over municipal services responsibilities. Helen Yu Lai Ching-ping, 58, Director of Regional Services, will head a taskforce on building safety and maintenance. The revamp was triggered by the bird flu in late 1997 which killed six people. Poor handling of the crisis led Tung Chee-hwa to order the abolition of the municipal councils, which had responsibility for environmental hygiene. They are to be scrapped on Friday. Mrs Yam said a new direction on food safety policy was needed to cope with world trends: 'We will balance the genuine needs and will not be led by one or two [pressure] groups only.' Guidelines on handling food crises will be issued to government departments. Mrs Lau pledged to provide a one-stop service for monitoring food safety. 'We will monitor importation, slaughter, checking and sale of food and licensing of restaurants,' she said.
