Animal testing is defined as any use of animals for a scientific or educational purpose, where there is assumed to be inflicted pain, suffering, anxiety or permanent damage to the animal, which is equivalent or stronger than what an injection with a needle - performed according to veterinary practices - would cause. The use of animals in experiments is only allowed after obtaining a permit from the Animal Experiments Inspectorate.
The majority of animal testing in Denmark is used to develop and test medicine for humans. The authorities require that all medicine is tested on animals before being administered to humans, to ensure that humans do not get sick from the new medicine. Animal testing is also used to develop new medicine for animals or to educate doctors and veterinarians in e.g. surgery.
