Prevalence of Parasitic Contamination in Salad Vegetables Collected from Supermarkets and Street Vendors in Amman and Baqa’a – Jordan
Journal Title: Polish Journal of Microbiology - Year 2016, Vol 65, Issue 2
Abstract
One of the main ways in transmitting parasites to humans is through consuming contaminated raw vegetables. The aim of this study was to evaluate the prevalence of parasitological contamination (helminthes eggs, [i]Giardia[/i] and [i]Entamoeba histolytica[/i] cysts) of salad vegetables sold at supermarkets and street vendors in Amman and Baqa’a – Jordan. A total of 133 sles of salad vegetables were collected and examined for the prevalence of parasites. It was found that 29% of the sles were contaminated with different parasites. Of the 30 lettuce, 33 tomato, 42 parsley and 28 cucumber sles examined the prevalence of [i]Ascaris[/i] spp. eggs was 43%, 15%, 21% and 4%; [i]Toxocara[/i] spp. eggs was 30%, 0%, 0% and 4%; [i]Giardia[/i] spp. cysts was 23%, 6%, 0% and 0%; [i]Taenia[/i]/[i]Echinococcus[/i] eggs was 20%, 0%, 5% and 0%; [i]Fasciola hepatica[/i] eggs was 13%, 3%, 2% and 0%; and [i]E. histolytica[/i] cysts was 10%, 6%, 0% and 0%, respectively. There was no significant difference in the prevalence of parasite in salad vegetables either between supermarkets and street vendors, or between Amman and Baqa’a, [i]Ascaris[/i] spp. was found to be the highest prevalent parasite in salad vegetables from supermarkets and street vendors and from Amman and Baqa’a. Our results pointed out that, the parasitic contamination of salad vegetables found in our study might be caused by irrigating crops with faecal contaminated water. We concluded that salad vegetables sold in Amman and Baqa’a may cause a health risk to consumers.
