EU-wide animal research statistics, 2020
  • The UK is no longer included in the statistics due to withdrawing from the EU in 2020 

  • 8,624,692 animals used for research in the EU (and Norway) in 2020  

  • Mice, fish, rats and birds account for 91% of animals used 

  • Cats, dogs, and primates account for 0.2% 

  • Germany was the highest user of animals 

  • The UK has already published its 2020 and 2021 animal research statistics 

On Tuesday, 4 April 2023, the European Commission has released its ‘Summary Report on the statistics on the use of animals for scientific purposes in the Member States of the European Union and Norway in 2020’. The figures show that 8,624,692 animals were used for scientific, medical and veterinary research across 27 Member States and Norway in 2020, 6.7% less than in 2019. 

The reduction is partially attributed to a reduced amount of research overall due to lockdown restrictions and cancelled projects in the Covid-19 pandemic. 

For the first time since 1991, the data from the UK is no longer reported due to the UK withdrawing from the EU in 2020. To allow for the comparisons with previous years using the same reporting countries, the EU has recalculated its data 2018 and 2019 to exclude the UK.   

The three countries that used the highest number of animals for experimental purposes in 2020 were: 

  • Germany: 1,494,563 animals used (18.8%) 

  • France: 1,477,344 animals used (18.6%) 

  • Norway: 1,410,152 animals used (17.8%)

In 2020, Great Britain and Northern Ireland used approximately 1,393,695 animals for the first time in experimental procedures. 

 

Purpose of animals used 

Of the 8,624,692 animals used in research in 2020, 7,938,064 animals (92%) were used for experimental purposes while 686,628 animals (8%) were used for the creation and breeding of genetically altered animals. Animals used for experimental purposes decreased by 7.5% compared to 2019, while animals used for the creation and breeding of genetically altered animals increased by 4.1%. 

91% of animals used for experimental purposes in 2020 were mice, fish, rats, and birds, whereas cats, dogs, and primates accounted for 0.2%.

Experimental purposes:

EU Stats 2020 large (2).pngUsing animals in scientific studies for purposes such as basic research and the development of treatments, safety testing of pharmaceuticals and other substances, education, specific surgical training and education, environmental research and species protection. 

Some animals are used more than once during research and in 2020 there were 8,054,930 procedures carried out on animals for experimental purposes, a 7.6% decrease compared to 2019. This includes basic research, which expands our knowledge of living organisms and the environment; applied research, which addresses the prevention of disease and development of treatments; and regulatory research, which includes studies aimed at ensuring product safety and the effectiveness of pharmaceuticals. Of these 8,054,930 procedures: 

  • 40.9% (3,293,349) were for basic research 
  • 31.2% (2,510,499) were for applied research 
  • 17.4% (1,404,240) were for regulatory research 
  • 10.5% (846,842) were for other purposes 

Creation and breeding of genetically altered animals:

The breeding of animals whose genes have mutated or have been modified. These animals are used to produce genetically altered offspring for use in experimental procedures but are not themselves used in experimental procedures. 

8% (686,628) of all animals used for research in 2020 were for the creation and breeding of genetically altered animals. Of these 686,628 animals used:  

  • 57% (388,729) were for the creation of new lines of genetically altered animals  
  • 43% (297,899) were for the purpose of maintenance of established lines of genetically altered animals 

 

Severity of procedures for experimental purposes  

Severity assessments measure the harm experienced by an animal during a procedure. A procedure can be as mild as an injection, or as severe as an organ transplant. Almost half (48.9%) of experimental procedures were classed as (up to and including) mild in 2020.

Severity assessments reflect the peak severity of the entire procedure and are classified into four different categories:   

Non-recovery: When the entire procedure takes place under general anaesthetic and the animal is humanely killed before waking up.  

Mild (up to and including): The procedure caused short-term mild pain, suffering or distress; or no significant impairment of the well-being or general condition of the animal. For example, the equivalent of an injection or having a blood sample taken. This category also includes any animals which have not experienced a level of pain, suffering, distress or lasting harm above the minimum threshold i.e., the equivalent caused by the introduction of a needle in accordance with good veterinary practice. 

Moderate: The procedure caused short-term moderate pain, suffering or distress; long-lasting mild pain, suffering or distress; or moderate impairment of the well-being or general condition of the animal. For example, surgery carried out under general anaesthesia followed by painkillers during recovery.  

Severe: The procedure caused severe pain, suffering or distress; long-lasting moderate pain, suffering or distress; or severe impairment of the well-being or general condition of the animal. This would usually include long-term disease processes where assistance with normal activities such as feeding and drinking were required, or where significant deficits in behaviours/activities persist. Animals found dead are commonly classified as severe as pre-mortality suffering often cannot be assessed. Most severe procedures arise in regulatory testing such as the evaluation of toxicity of drugs.  

 

UK statistics 

Since supplying their figures to the EU, some countries, including the UK, have also published statistics for 2020 and 2021. Statistics on animal use in 2021 for Great Britain can be found here. The EU will continue to publish the EU statistics annually. However, as a result of the UK withdrawing from the EU in 2020, the data from the UK will no longer be included. 

In the EU animal research is strictly regulated under the EU Directive 2010/63. Every procedure, from a simple blood test to major surgery, requires individual, establishment and project licences, as well as approval from animal welfare and ethical review bodies. 

All organisations are committed to the ‘3Rs’ of replacement, reduction and refinement. This means avoiding or replacing the use of animals where possible; minimising the number of animals used per experiment and optimising the experience of the animals to improve animal welfare. 

The use of animals to test tobacco products was banned in the UK in 1997 and it has been illegal to use animals to test cosmetic products in this country since 1998. A policy ban on household product testing using animals was introduced in 2010. Since 2013, it has been illegal to sell or import cosmetics anywhere in the EU where the finished product or its ingredients have been tested on animals.
