Results of the present study has shown that 76 out of 470 samples (16%) contained parasite stages. Depending on the type of leafy plant examined the prevalence of parasitic stages in these plants was found to be 27.8% (17/61) in lettuce, 22.8% (13/57) in watercress, 20.6% (7/34) in leek, 19.1% (9/47) in green onion, 17.4% (15/87) in parsley, 15.4% (4/26) in spinach, 13.6% (3/22) in basil, 11.5% (3/26) in coriander, 9.4% (3/32) in radish, 5.3% (1/19) in dill and 4.7% (2/42) in mint. No parasites were detected in 17 samples collected from cabbage. Stages of intestinal parasites detected were Entamoeba coli (35.5%), Giardia lamblia (31.6%), Dicrocoelium sp. (28.9%), Ascaris sp. (26.3%), Taenia sp. (19.7%), Blastocystis hominis (17.1%), Fasciola sp. (14.5%), Hymenolepis sp. (14.5%), Ancylostoma sp. (11.8%), Toxoplasma gondii (6.6%) and Trichostrongylus sp. (2.6%).
