The present study has been done to assess the degree of contamination of fresh leafy vegetables with parasites in some farms in Dhamar city, Yemen. The results have shown that all 70 examined samples of the selected five types of vegetables were positive for 100% contamination with parasites. The examined vegetables Allium porrum, Nasturtium officinale, Coriandrum sativum, Petroselium hortens and Lactuce sativa were fresh leafy and they are commonly used daily as a green salad by consumers. The intestinal parasites which have been found belong to protozoa and helminthes. The protozoan parasites which have been reported in this study are Entamoeba histolytica (26.9%), Entamoeba coli (18.2%), Balantidium coli (3.8%) and Giaredia lamblia (3.8%). The reported helminthes are (Ascaris lumbricoides (12.5%), Hymenolepis nana (1.9%), Hymenolepis diminuta (1.9%), Enterobuse (19.2%), Taeniasa ginata (6.7%), Heterophyes heterophyes (0.9%), Fasciola hepatica (2.8%)and Hook worm (0.9%). Allium porrum has shown contamination of (25%) which is the highest poly-parasitic contamination of twelve species of parasites followed by Nasturtium officinale (22.11%), Coriandrum sativum (18.2%) and Petroselium hortens (18.2%), whereas Lactuce sativa (16.3%) showed the least of poly-parasitic contamination of parasites. The degree of contamination in 7 different chosen farms in Dhamar city has shown that the highest intensity contamination was found in (farm3, farm4 and farm5) with (17.3%) each, followed by farm1 (13.5%), farm 2 and farm 6 (12.5%) each where farm7 (9.6%) was the least contaminated farm.
