The World Organisation for Animal Health (OIE) is an intergovernmental organisation with a mandate from its 178 Member Countries and Territories to improve animal health and welfare in the world. The OIE is the reference standard-setting international organization according to the Sanitary and Phytosanitary Agreement of the World Trade Organisation. It is notably responsible for ensuring transparency of the animal disease situation worldwide, including diseases transmissible to humans, as well as safeguarding the sanitary safety of world trade of animals and animal products. Since 2000 the organisation also publishes international standards on animal welfare.

Besides first-conducted actions of the previous plans, the 5th Strategic Plan adopted in May 2010 for the years 2011-2015 targets: more activities directed to food security, poverty alleviation; more focus on the “One Health” concept; the impact of climate and environmental changes on animal disease emergence and occurrence as well as the impact of animal production on climate change.
