A total of 261 vegetable samples and315 stool samples of school children were collected from Kathmandu Valley. The stool samples were examined by formal-ether technique and direct smear technique.For vegetables, saturated brineflotation method was used. Out of total vegetable samples, 29.5% (77/261) were found to be contaminated with different parasites, Cyclosporaspp. being the most prevalent (28.4%, 74/261) . Thehigh rate of contamination was found in wet season (32.2%, 50/154) than dry season(25.2%, 27/107) (P>0.05). In school children, the overall prevalence rate of parasitic infections was 65.4%, helminth parasites being dominant. Trichuris trichiura(29.2%)was the most common helminth. The female children had the higher parasitic prevalence rate (68.3%, 122/178) than the male counterparts (61.3%, 84/137)(P>0.05). The prevalence of multiparasitism was 61.6% while that of monoparasitism was 38.4%. Indo-Aryans had significantly higher prevalence rate (66.3%, 67/101)followed byTibeto-Burmans(65.7%, 117/178) and Dalits(61.1%, 22/36) (P>0.05).The children without toilet at their home were more infected (79.5%, 58/73) than that of having toilet (61.2%, 148/242) (P<0.05). The children of farmers had higherprevalence rate (73.9%) than other occupation. The high prevalence of parasiticinfection (67.0%) was found in those children who had not taken anthelminthic drug in past six months compared to those who had taken the drugs (33.3%) (P<0.05). Thechildren without nail cut had the more prevalence (74.2%) of parasitic infection thanthose with nail cut (61.2%) (P<0.05).
