Primate Research in Numbers
In 2019, a total of 234 primates were used in Switzerland for research purposes at companies and universities. This comprises about 0.05 percent of all animal testing.
The severity of every animal testing project is classified according to a four-level system both "prospectively" at the time of the application, and "retrospectively" at the time of project completion. This classification system describes the level, intensity and duration of distress caused to the animals.
Most of these experiments were categorised as low severity, which means they were either non-stressful or only slightly stressful for the animals involved.
