Directive 2010/63/EU[1] is the European Union (EU) legislation "on the protection of animals used for scientific purposes" and is one of the most stringent ethical and welfare standards worldwide.[2]
The Directive repealed Directive 86/609/EEC. It became formally applied across the EU on 1 January 2013. It protects live non-human vertebrates including independently feeding larval forms and foetal forms of mammals from the last third of their normal development, and live cephalopods.
