Shamrock Farm was the United Kingdom's only non-human primate importation and quarantine centre, located in Small Dole, near Henfield in West Sussex. The centre, owned by Bausch and Lomb and run by Charles River Laboratories, Inc. for Shamrock (GB) Ltd, provided animals to various laboratories and universities for use in animal testing. It was Europe's largest supplier of primates to laboratories, and held up to 350 monkeys at a time.
It closed in 2000 after a 15-month protest by British animal rights activists, who campaigned under the name "Save the Shamrock Monkeys."[1]
