Prior to the
transfer of sovereignty in 1997 it was named Health and Welfare Branch. When the
Principal Officials Accountability System (POAS) was introduced in July 2002, the name of the Bureau was renamed from Health and Welfare Bureau to the name of Health, Welfare and Food Bureau, with the
Food and Environmental Hygiene Department being transferred from the now abolished
Environment and Food Bureau. In July 2007, the bureau was further renamed Food and Health Bureau, with its functions on welfare transferred to the
Labour and Welfare Bureau. As part of the government bureaux restructuring initiated by incoming
Chief Executive John Lee, the Food and Health Bureau was abolished on 1 July 2022. The
Health Bureau is the direct successor agency of the former Food and Health Bureau, taking over the remaining policy portfolios after those on environmental hygiene, food safety, agriculture and fisheries, and veterinary public health were transferred to the
Environment and Ecology Bureau. ==Portfolio==
