At present it is not possible to ban outright the use of animals for safety testing or biomedical research. The revision thus seeks to ensure that animals are used only where no other means are available. Their use must be fully justifiable and the expected benefits must outweigh the harm caused to the animals. The new Directive would also ensure that animals receive suitable care and treatment such as appropriately sized cages and an environment adapted to each species. These provisions will be continually monitored.
