Background and Objective: Parasitic diseases are the most important infectious disorders and one of the main public health problems in many communities. One of the most important ways of parasite infection is to consume the raw vegetables. The aim of this study is to assess the parasitic contaminations of fresh consumed vegetables in Qom.
Materials and Methods: This is a cross-sectional study in which 840 samples of different vegetables including leek, parsley, lettuce, coriander, radish, spring onion, tarragon, basil, mint, and cress collected from 42 vegetable sellers in Qom during 3 months in 2014 were examined. Samples were evaluated for presence of metazoan and protozoan parasitic contaminations. The vegetables were washed with water and tested microscopically after performance of sedimentation method. Results were reported as descriptive statistics (average and percentage).
Results: In 265 out of 840 samples (31.55%) were found to have parasitic contamination. Among those 110 (41.51%) and 155 (58.49%) were revealed to be metazoa and protozoa, respectively. The highest rate of contamination was detected in leek and parsley with 48 positive samples (18.11%) and the lowest one in coriander radish and lettuce with 9 (3.39%) and 7 (2.65%) samples were positive respectively. Regarding the parasitic infestations, Entamoeba coli cyst with 113 positive samples (42.64%) and Ascaris ova with 59 positive samples (22.25%) had the most pollution and Oxyuris ova with 4 positive samples (1.51%) had the less pollution among consuming vegetables.
Conclusion: The results revealed that the percentage of vegetables contamination in Qom city was middle. It would be recommended that the essential measures should be taken to increase the awareness level of people about the proper disinfection of vegetables.
