The parliamentary office for the evaluation of scientific and technological choices (OPECST) has just published a report on the use of animals in research and alternatives to animal testing, based on the holding of two contradictory round tables (rapporteurs: Cédric Villani, MP; Florence Lassarade, Senator).

But as it notes that their use remains necessary, there is a conflict, and “ethical” principles are defined; they are based on the “3Rs”: replacement, reduction, refinement. It is a question, when launching an animal experiment: of ensuring that another method cannot be used (so-called alternative method); if not, minimize the number of animals used; and finally to improve the conditions of accommodation for animals, while respecting their vital and social needs (if a cage life can meet these needs), and the conditions for experimentation (mastery of pain, etc.).
