Stop Huntingdon Animal Cruelty (SHAC) - Stop Huntingdon Animal Cruelty (SHAC) is an international animal rightscampaign to close down Huntingdon Life Sciences (HLS), Europe's largest contract animal-testing laboratory. HLS tests medical and non-medical substances on around 75,000 animals every year, from rats to primates. It has been the subject of several major leaks or undercover investigations by activists and reporters since 1989.
SHAC was started in November 1999 by three British animal rights activists — Greg Avery, Heather James and Natasha Dellemagne — after video footage shot covertly inside HLS in 1997 by People for the Ethical Treatment of Animals (PETA) showed HLS staff shaking, punching, and shouting at beagles in their care. The footage was broadcast by Channel 4 in the UK, the employees were dismissed and prosecuted, and HLS's licence to perform animal experiments was revoked for six months. PETA stopped its protests against the company after HLS threatened it with legal action, and SHAC took over as a leaderless resistance.
