The need to fight animal diseases at global level led to the creation of the Office International des Epizooties through the international Agreement signed on January 25th 1924. In May 2003 the Office became the World Organisation for Animal Health but kept its historical acronym OIE.
The OIE is the intergovernmental organisation responsible for improving animal health worldwide.
It is recognised as a reference organisation by the World Trade Organization (WTO) and in 2016 has a total of 180 Member Countries. The OIE maintains permanent relations with 71 other international and regional organisations and has Regional and sub-regional Offices on every continent.
The organisation is placed under the authority and control of a World Assembly of Delegates consisting of Delegates designated by the Governments of all Member Countries.
The day-to-day operation of the OIE is managed at the Headquarters situated in Paris and placed under the responsibility of a Director General elected by the World Assembly of Delegates.
