World organisation for animal health or OIE is an intergovernmental organisation involved in coordinating international animal disease control. It was established in 1924 and is headquartered in Paris, France. It is recognised by the WTO with respect to standards for international sanitary rules. India is one of the member countries. Recently, the OIE released a revised manual for culling of infected birds. The revised edition requires the administration of anaesthesia before culling (if the birds weigh over 3kg).
