The FSA was established as a non-ministerial Government Department in 2000. Its primary purpose was to secure food safety and provide vital advice to Government and to the public; a role that the Government believes must remain independent.
Reorganising in this way will contribute to the Government’s objectives to improve efficiency, and is paramount to the key priority of improving the health of the nation by creating a public health service.
