The Prevalence of Parasitic Contamination of Fresh Vegetables in Tehran, Iran
Turkiye Parazitol Derg. 2020 09 04; 44(3):143-148.TP

Abstract

Objective

Parasitic diseases have created numerous health and economic problems in developing and developed countries. One of the most prevalent ways of transmitting diseases is by consuming raw vegetables that are contaminated with parasites. With respect to the importance of healthy vegetable consumption, an awareness of vegetable status helps prevent infection. Therefore, the present study was conducted to determine the level of parasitic contamination of vegetables consumed in Tehran.

Methods

This descriptive and cross-sectional study was conducted on vegetable samples spread in Tehran from October 2017 to September 2018. The samples included 240 vegetables selected from 10 types of vegetable including leek, basil, mint, spring onion, radish, parsley, lettuce, cress, tarragon and coriander. Each sample was examined after passing through washing and centrifuging. Parasitic agents such as unicellular, egg and larva of the worms were studied. The data were analysed using SPSS software.

Conclusion

Parasitic infection was observed in 62 samples (25.8%). The highest and lowest rates of contamination were observed in coriander and lettuce, respectively. Rhabditoid larva (12.5%; 15 cases) and Physaloptera egg (1.6%; 2 cases) were the most and least observed parasites, respectively. Other parasites such as Entamoeba, Giardia, Blastocystis, Hymenolepis, Ascaris and the egg and larva of hookworms were also observed. Despite the relative improvement of social, agricultural, economic and health conditions in Tehran, the prevalence of parasitic infections still persists. Factors such as developing modern waste collection methods, improving urban sewage systems, preventing domestic animal traffic on pastures and promoting the knowledge of different classes of people could reduce the prevalence of these types of diseases.
