We did it! After a global campaign by PETA entities, French pharmaceutical giant Sanofi will no longer torment tiny animals in a near-drowning experiment known as the forced swim test.

The move follows a campaign that included outreach from PETA scientists and more than 440,000 e-mails from supporters in Australia and around the world.

Sanofi

Sanofi announced the compassionate change with a new public policy confirming that the company “does not use the Porsolt swim test”. It stated, “We have no research projects that involve the use of this test and have no plans for this test to be used in the future, either in-house or at a contract research partner.”

Between 1993 and 2019, Sanofi tormented more than 1,500 mice and rats in the test – and failed to produce a single usable antidepressant.

The Forced Swim Test

In the widely discredited test, experimenters force rats, mice, or other small animals into inescapable beakers of water and watch them desperately swim in search of an escape in the erroneous belief that this can reveal something about human mental health conditions. Once the test is complete, experimenters kill the animals.

Ending Near-Drowning Experiments on Animals

PETA entities around the world have been pressing for an end to the use of the test globally, with actions taken including outreach by scientists, protests, PETA-proposed shareholder resolutions, and e-mails and calls from our supporters. Recent updates from Australia and New Zealand include:

La Trobe University—June 2024 
Following conversations with PETA entities regarding the ineffectiveness and suffering associated with the forced swim test, La Trobe University officials have agreed to prohibit the use of the forced swim test to model human depression, anxiety disorders, and their treatment, in agreement with the Australian National Health and Medical Research Council’s guidance. La Trobe University employees’ last published paper using the forced swim test was in 2022 and officials there also confirmed that no one at the school is currently conducting the test. Learn more.

Parliament of New South Wales—March 2024
It is now illegal to conduct new forced swim tests in New South Wales. Thanks to legislation introduced by the Animal Justice Party and advanced by Animal-Free Science Advocacy (AFSA), mounting new projects that force mice and other mammals to experience the panic of near-drowning will no longer be allowed. PETA has long protested against the cruel and flawed forced swim test and has been working with AFSA to end the use of this experiment in Australia. Learn more.

Australian Research Council—January 2024
After hearing from Animal-Free Science Advocacy, the Australian Research Council, which acts as the government’s primary non-medical research funding agency, has now endorsed the National Health and Medical Research Council’s (NHMRC) decision that prohibits funding any experiments that use the test to model human depression in order to study “depression-like behaviour” or anxiety disorders and their treatment. NHMRC updated its advice last year following requests by PETA and Animal-Free Science Advocacy.

AgResearch (New Zealand)—January 2024
PETA also helped put another nail in the coffin of the cruel and pointless forced swim test, aiding NZAVS in securing New Zealand’s ban on the bogus test. Thanks to the combined effort, the forced swim test is now effectively banned in one-third of Aotearoa’s research institutions, and no university in the country is using this unscientific experiment, sparing countless animals pointless torment.

National Health and Medical Research Council—December 2023
Following requests from PETA and Animal-Free Science Advocacy starting in 2020, the Australian National Health and Medical Research Council (NHMRC) finalized its advice on the forced swim test. In its updated policy, NHMRC recognizes that the test has a significant impact on animal welfare. The policy now prohibits the council from funding any experiments that use the test to model human depression in order to study “depression-like behaviour” or anxiety disorders and their treatment.

University of Western Australia—December 2023
After hearing from PETA and PETA US as well as Animal-Free Science Advocacy, the University of Western Australia confirmed that it has ended its use of the widely discredited and cruel forced swim test. This decision comes after over 25,000 PETA supporters wrote to the university urging it to drop the test. In a letter to PETA regarding the ban, a university representative confirmed that “UWA no longer conducts any active projects that make use of the forced swim test”. Learn more.

Help Ban the Forced Swim Test

The forced swim test is purportedly conducted to study human depression and test the efficacy of antidepressants, but experts have strongly and repeatedly debunked the experiment’s validity.

Please take action by urging Australian universities to ban this worthless test.
