Investigation of parasitic contamination of edible vegetables in Isfahan city in 2021

One of the most important ways of transmitting parasites to humans is consuming raw vegetables. Parasites may be transmitted to consumers through Unwashed vegetables. This study was conducted with the aim of determining the amount and type of parasites present in vegetables distributed in the supply centers of Isfahan city in 2021.

8 regions from 12 regions in Isfahan and two shops from each region were selected. 2 samples of 100 gr of vegetables were taken from each store. Each sample entered a bucket containing 1 liter of water and 1.8 ml of Tween 80. The vegetables were removed from the bucket after 30 minutes and the water obtained from washing them was examined after 24 to 48 hours by flotation method with sucrose. Ethical considerations were considered throughout all stages of the study.

10% of the samples had one type of parasitic infection, the highest frequency of isolated parasitic was related to Blastocystis hominis [12.5%] and lowest in [3.1%] related to Ascaris lumbricoides, Trichiura Trichuris, Isospora spp, stercorali Strongyloides, Cyclospora cayetanensis. The largest amount of pollution is seen in the more green and radishes has a parasitic infection.

Raw vegetables have at least one type of parasite. The type of parasites found in raw vegetables shows that human fertilizers and wastewater effluents are used in vegetable irrigation. Therefore, it is very necessary to teach vegetables to be healthy based on health recipes and avoid consuming raw vegetables before they are healthy, to minimize the transmission of parasites.
