Concerns have been raised by welfare organisations as to whether forced swim tests remain appropriate. Photograph: iStockThe forced swim test (FST) should not be used on animals in depression and anxiety studies, according to new guidelines from the medicines watchdog. In these tests, rodents are placed into inescapable containers of water, where they then struggle to escape and stay afloat. People for the Ethical Treatment of Animals (Peta) has been lobbying for a ban on the use of this test due to the harm it causes to the animals. It also recommended that researchers consult their ethics committee and their designated veterinarian before including this test in a project proposal.
