The OIE (World Organization for Animal Health) is an intergovernmental organization created in 1924. As of 2017, the OIE membership represents a total of 181 Countries and Territories. 
Its mission is: 

- To ensure transparency in the global animal disease situation

- To provide expertise and encourage international solidarity in the control of animal diseases
- To safeguard world trade by publishing health standards for international trade in animals and animal products 
- To improve the legal framework and resources of National Veterinary Services Organization 

According to the OIE (World Animal Health Organization), there is no risk of Bovine Spongiform Encephalopathy (BSE) being transmitted in several products, including: milk, hides and skins, deboned meat, and blood and blood by-products, such as fetal bovine serum (OIE Terrestrial Code 11.4 BSE). Most OIE member countries have adopted this position, including the European Union and the United States (USDA). For some time, BSE was used as an argument favouring certain origins. After the OIE determined that BSE was not transmitted by blood products, these arguments have become obsolete
