During the period January to August 1968, 979 pigs slaughtered at the two local abattoirs in Cheju-do were investigated for Cysticercus cellulosae infection. The results obtained are as follows.
1. A total of 72(7.35%) out of 979 pigs examined were found to be infected with Cysticercus cellulosae. Among the positive pigs, 31(9.2%) were detected at Hallim abattoir and 41(6.4%) at Sogwipo abattoir,respectively.
2. Among the various sites examined, the axial muscles(91.3%) was the most frequent site of infection. The other sites in the order of diminishing frequency were the thigh and gluteal muscles(78.2%), the neck and masticatory muscles(65.2%), the heart and tongue(39.1%), the shoulder muscles(26.0%), the diaphragm(8.7%), and the eye and liver(4.3%). The evidence of infection was not found in the lung of all the positive pigs.
3. The number of cysts contained in the central part of the thigh and gluteal muscles (10cm×10cm×3cm) of 23 infected pigs was examined. The highest number of cysts was 352 and the lowest number was one. The average number of cysts was 70.2.
4. It was concluded, on the basis of the observations on the origin of the positive pigs and the sanitary condition of each of the farms, that human feces is the main source of infection on pigs in Cheju-do.
