High Quality Content by WIKIPEDIA articles! Shamrock Farm was Britain's only non-human primate importation and quarantine centre, located in Small Dole, near Brighton in West Sussex. The centre, owned by Bausch and Lomb, and run by Charles River Laboratories, Inc. for Shamrock (GB) Ltd, closed in 2000 after a 15-month protest by British animal rights activists, who campaigned under the name "Save the Shamrock Monkeys." The company was set up in 1954, trading in wild-caught primates until 1993 and captive-bred ones thereafter.
