Abstract

 Background: Outbreaks of human parasitic diseases associated with the consumption of raw VEGETABLES, often occur in developing and developed countries.Objective: To evaluate parasitic contamination of edible VEGETABLES in Qazvin.Methods: This was a descriptive analytical study in which 150 samples of different VEGETABLES including leek, parsley, lettuce, coriander, radish, spring onion, tarragon, basil, mint, and cress; collected from several greengroceries in Qazvin during 12 months between 2006-2007 were examined. Samples were evaluated for presence of metazoan and protozoan parasitic contaminations. The vegetable samples were washed with water and tested microscopically after performance of sedimentation method.Findings: Fifty three out of 150 samples (35.3%) were found to have parasitic contamination. Among those 45 (30%) and 8 (5.3%) were revealed to be metazoa and protozoa, respectively. Metazoan contaminations were detected by observation of helminthes’ eggs 13 (8.6%) and rhabditoid larva 32 (21.4%) in VEGETABLES. The highest rate of contamination was detected in leek (60%), and the lowest in coriander and radish (20%). Regarding the parasitic infestation, rhabditoid larva with 21.4% and Hymenolepis nana ova with 0.7% were shown to have the highest and lowest rates, respectively.Conclusion: Based on our results, edible VEGETABLES in Qazvin are the potential sources of several PARASITIC INFECTIONS in human.
