Demonstration on April, 26th against the expansion of the primatology station in Rousset (France)
On the occasion of the World Day for Laboratory Animals, One Voice and the CVPA-Collectif Vauclusien de Protection Animale are organising a joint demonstration on Saturday April, 26th 2025 from 1.45pm in front of the Rousset town hall (France) to oppose the project to expand the CNRS primatology station and increase the number of primates destined for laboratories.
At a time when research across many fields is moving beyond animal experimentation and alternative methods are proving increasingly, the CNRS is investing heavily in extending its primatology station at Rousset, 16 km from Aix-en-Provence.
The aim? To transform the station into a national primatology centre, tripling its capacity. The site would be expanded from 600 to 1,740 primates (baboons, macaques, squirrel monkeys and marmosets) destined for use in French laboratories.
A public tender for the expansion work has already been issued.
This project, costing over €30 million and funded by taxpayers, goes against the European Directive 2010/63/EU, which promotes ‘the total replacement of procedures applied to live animals for scientific or educational purposes, as soon as scientifically possible’.
Let’s recall that three quarters of French citizens are opposed to animal experimentation, 81% are opposed to experiments on primates and 80% support the closure of primate breeding facilities in France.
Does it still make sense to launch such a breeding project in 2025 knowing that its construction will not be completed before 2030 and that it will then take a further 4 to 5 years to ‘produce’ enough primates for a demand that will likely have shifted by then?
We strongly doubt it. This is why One Voice and the Collectif Vauclusien de Protection Animale, supported by more than fifty national and international organisations (associations, collectives, foundations, parties, etc.), will gather on April,26th from 1.45pm to voice two demands:
- an ethical, scientific and economic assessment of the relevance of the extension project by an independent committee,
- the reallocation of public funds towards innovative animal-free research methods.
