Over 1.18 million animals experienced moderate to severe pain in UK labs in a single recent year. This article presents the global data on animal testing, detailing the scale of use, the suffering inflicted, and the regulatory shortcomings that perpetuate the practice.
Key Takeaways
- In 2022, over 1.18 million animals were used in research in the UK, with 97% experiencing moderate to severe pain
- In UK 2022, 88% of procedures caused moderate to severe suffering
- 95% of drugs failing animal tests also fail in humans
- EU 2021: 1.9 million mice used, highest species
- Toxicity testing accounts for 40-50% of all animal experiments globally
Animal testing still affects hundreds of millions each year, showing why stricter protections are urgently needed.

Interpretation
Annual Usage Numbers Interpretation
The grim global ledger reveals our reliance on sentient suffering as scientific currency, where millions of lives are reduced to annual statistics and the overwhelming majority of their experiences are written in a language of pain, all while being meticulously excluded from the very regulations designed to protect them.
