To establish a statistically reliable sampling strategy for serological surveillance of classical swine fever (CSF) in Korea, antibody test data from CSF surveillance conducted during year 2005 were analyzed. The most appropriate sampling method was determined to be stratified multi-stage random sampling strategy, in which the primary sampling unit is a pig farm and the secondary are the pigs by the strata of breeders and finishers in the selected farm. The optimum sample size was 5 to 19 including 1 to 2 breeders according to the number of pigs in the farm.
