The Federal Food Safety and Veterinary Office has published on the 30 August 2018 Technical information on animal experimentation regarding severity degrees. The document provides information for the attention of the cantonal authorities responsible for animal experiments, their advisory committees and all persons concerned with animal experiments. It is intended to serve as a guideline for careful assessment of the severity of animal experiments and the genetic constraints on the animals, in order to allow correct classification of animal experiments in severity categories. It is also intended to promote efforts to find less constraining animal models and experimental procedures and thus to support the implementation of the 3R principles in the longer term. More info can be found on the FSVO website.
