Severity degrees of animal experiments
During an experiment, animals are exposed to various degrees of distress caused by interventions and measures. These stresses are divided into four different categories known as severity degrees. This classification is Download published (PDF, 710 KB) by the Federal Food Safety and Veterinary Office (external page FSVO ) and applied by the authorising cantonal veterinary offices.
When assessing the degree of animal suffering, the cumulative effect is also taken into account if several interventions and measures are carried out on the same animal.
