대구시내의 비륭 시장에서 엽채류 등 상치 열무 및 배추를 구입하여 기생충란과 유충의 부착상을 1982연 7월부터 1983연 6월까지 1연간에 걸쳐서 조사하여 이(1969)와 최·이(1972)의 조사성적과 비교하였다. 율소엽은 단단한 솔로 세척하여 부착된 기생충의 종유, 부착률 및 채소 200g당 기생충란의 평균 부착수를 조사하였다. 채소엽에서 4종의 기생기란 회충, 모양선충, 구직및 간흡충란과 2종의 유충 기충의 사상 및 간상유충을 찾아 볼 수 있었다. 이 중 회충란의 부착률은 4.2%로서 가장 높았으며 다음은 구충란으로서 3.6%였다. 채소 2009당 회충란의 부착수는 열무 0.6f권, 상치 및 배추는 각각 0.3개였고 기충의 사상발충은 열무 0.4%, 상치 0.3개, 배추 0.1개였으며 간상유충은 열무 0.2%, 상치 0.1%, 배추 0.05개로서 간상유충보다 사상유충이 많이 부착되어 있었다. 이(1969)와 최·이(1972)의 조사성적에서는 채소 200g당 회충란의 부착수는 열무 7.5%, 상치 3.1%, 배추 0.5개였는데 비하여 이번 조사성속에서는 열무 0.6개, 상치 및 배추는 각각 0.3개로서 심히 감소되었음을 나타내었다.
A survey on vegetables, which consisted of lettuce (Lactuca sativa) , young radish (Raphanus sapiwus), and chinese cabbage (Brassica pekinensis) collected from 6 markets in the Taegu city, was conducted for the discovery of helminth eggs and larvae, from July, 1982 to June, 1983. The results were compared with the data obtained from vegetables collected at the same markets by Lee (1969) and Choi and Lee (1972). Both sides of vegetable leaves were washed carefully with a hard brush, and the species of parasites and the mean number of parasites per 200g of vegetable were determined. When vegetable were examined, 4 species of parasite eggs (ascarid, Trichostrongylus, liver fluke, and hookworms) and 2 larvae (filariform and rhabditoid larvae) were found. Of the parasite discovered, ascarid egg was found to be highest (4.2%) , followed by hookworm egg (3.6%) . The mean number of ascarid egg per 200 grams of vegetable was 0.6 in young radishes, and 0.3 in both lettuces and and chinese cabbages. Similarly, the number of filariform larva of hookworm was 0.4 in young radishes, 0.3 in lettuces, and 0.1 in chinese cabbages, and the number of rhabditoid larva was 0.2 in young radishes, 0.1 in lettuces, and 0.05 in chinese cabbages. In the results obtained by Lee (1969) and Choi and Lee (1972) , the mean number of ascarid egg per 200 grams of vegetable was 7.5 in young radishes, 3.1 in lettuces, and 0.5 in chinese cabbages. By contrast, in the present study it was 0.6 in young radishes an 0.3 in both lettuces and chinese cabbages. These results suggest that there has been significant reduction in the incidence of parasite egg and larva on vegetable leaves during the past 10 years.
