A study on eating habits of second intermediate hosts (fresh-water fishes, crayfish and crabs) of Clonorchis sinensis and Paragonimus westermant was made in Pusan area residents during the period of 6 months from May to October of 1962, by the questionnaire formula. A total of 9,155 persons(male: 4,223, female: 4,932)responded during this study.
An analysis of the study revealed that:
1) The eating rate of fresh-water fishes of Pusan citizens was 59.1%(male: 64.8%, female: 53.7%), and the rate of rural woman and city women were 74.9% and 61.4% respectively. The ways of the eating in both of Pusan citizens and rural women were boiling, which was the most common, and next raw eating, roasting, frying, soaking in salt and drying, in that order.
2) The eating rate of the crayfish and crabs of Pusan citizens was 48.6%(male:54.5%, female: 41.7%), and the rate of rural women and city women were 60.4% and 38.3% respectively. The most popular way of eating among both of Pusan citizens and rural women was boiling. Roasting was the second commonest way and soaking in soy-souce, raw eating and frying followed.
