Animal Testing at Liverpool University

Merseyside Animal Rights has obtained information indicating that the University of Liverpool conducted 14,112 experiments on animals in 2024, with a further 3,538 mice and 20 zebra fish that were killed without being experimented on. None were re-homed. We obtained the information via a Freedom Of Information request. The overall figure for the previous year was 12,936.

151 of these procedures inflicted severe pain on the animals used, 3883 inflicted moderate pain, 6846 inflicted mild pain, 3184 were described as ‘sub-threshold’, indicating they didn’t inflict any noticeable pain on the animal, while 98 led to ‘non-recovery’, meaning they were performed under general anaesthetic and from which the animal did not recover consciousness.

Of the animals used the vast majority were mice with 8,390 being experimented on, followed by 2,668 sheep, 1,965 cows, 619 rats, 194 hamsters, 168 birds, 104 rabbits, and 4 other mammals, each and every one a sentient creature with the ability to feel pain.

No breakdown of these figures was provided this year for the intended use of these experiments, eg. basic research, education purposes, studying human diseases, etc.
The figures we have obtained since 2014, when they first started recording them, show an increase in the last year in the numbers of experiments, following a period of steady decrease. It is hoped that this will be reversed in 2025.

The University of Liverpool claims to embrace the principles of reduction, refinement and replacement (known as ‘the 3Rs’) with regards to animal testing, and to be committed to the development of alternative methods. In terms of refinement which refers in part to how much pain is inflicted on animals, the number of animals subjected to severe pain has dropped by 88% in 2024, but for mild pain there’s a 50% increase.

Whilst the number of mice (their most-used animal) experimented on has dropped by about 20%, there has been a doubling of experiments on rats and sheep, whilst the number of cows used has tripled. The numbers of domestic fowl experimented on has decreased by about 75%, but the ‘other birds’ represent a new category of animal used. There are smaller changes (up & down) in the other categories, whilst the number of animals killed without being used has barely changed in the last five years.

The use of non-human animals as models for both toxicity testing and human disease research is increasingly being called into question. Differences between species means that the results delivered are often inaccurate and frequently dangerous. Nine out of every ten new drugs developed and passed as safe and effective in animals never lead to any human benefit due to ineffectiveness or unexpected toxicity when trialled in people. The use of non-human animals is actually delaying medical progress as well as posing a safety threat to those who volunteer for drugs trials.

Positively, in recent years, there has been a shift in focus towards the replacement aspect of the 3Rs with calls from within the scientific community to accelerate the replacement of animals in research and testing with more human relevant alternatives on both scientific and ethical grounds. Unfortunately, the University of Liverpool seems determined – despite its claims to the contrary – to remain bound to the outdated animal model for research.
