The Speaking of Research website aims is one of the biggest and most accurate resources for information about animal research worldwide. In our mission to provide as much information as possible, we have recently added a page on the European Union’s regulation of animal experiments. While regulations across the 28-EU countries are created and implemented at a national level, they must all conform to EU Directive 2010/63, which aims to harmonise the regulations between member countries.
Our new page on “Animal Research Regulation in the EU“, adds to those pages on UK and US legislation, to help people understand the requirements that EU Directive 2010/63 places on EU member countries.
See an overview of EU legislation below:
Countries in Europe have differing systems of regulation, but those within the European Union must meet the standards set out by EU Directive 2010/63/EU. The purpose of the Directive is to harmonise standards across the EU, as well as to promote and implement the 3Rs – Replacement, Refinement and Reduction of animals used for research. The Directive was adopted in 2010, but member states were given until January 2013 to transpose these regulations into domestic law.
Where specific parts of a country’s laboratory animal welfare standards were higher, they were permitted to retain them, for example, the UK retains its additional protections for cats, dogs, horses and primates. However, overall, the minimum regulations set by the EU are high by international standards. Every aspect from cage sizes to staff training is covered, with the 3Rs of Reduction, Replacement and Refinement at the heart of the Directive’s aims. The Directive requires a risk-based inspection regime and lays down minimum standards for housing and care, and systematic project evaluation. While the UK follows these EU regulations, we have written about their specific rules and regulations on our Animal Research Regulations in the UK page. In March 2017, the UK gave notice of its intention to leave the EU, however, the Government has so far suggested it intends to maintain its current animal welfare legislation after Brexit.
The legislation covers non-human vertebrate species (including independently feeding larval forms and last trimester foetal forms of mammals) and cephalopods.

All EU countries must also provide public statistics outlining the numbers of animal procedures completed each year. These are broken down in many ways, including by species, by type of research, and by severity. Speaking of Research provide analysis of these national statistical releases, which can be found on our Animal Research Statistics page. Across the EU, mice, rats, birds and fish tend to account for over 90% of the animals used in each country.
Scientists must also produce a non-technical summary of their experiment – essentially an abstract stripped of esoteric language so it can be understood by a layman. In countries such as the UK, these are made available on the regulator’s website for the general public to see (UK example).
