Parasitic contamination of vegetables marketed in Arba Minch town, southern Ethiopia.

Abstract：

BACKGROUND:Consumption of unwashed, raw or unhygienically prepared fruits and vegetables act as potential source for the spread of various parasitic diseases. Moreover, the level of contamination and species of contaminant parasites vary from place to place because of variations in environmental and human factors. Therefore local determination of the level of contamination and associated factors is important for efficient intervention of infections acquired via those food items. METHODS:A Cross-sectional study was conducted among purchased vegetables in selected markets of Arba Minch town from January to March, 2018. A structured questionnaire was used to capture data about factors associated with parasitic contamination of vegetables in the marketing phase. Selected vegetables were purchased and processed for examination of parasitic contamination using direct wet mount, iodine wet mount and modified zeihl Neelson staining following standard protocols. All data were analyzed using SPSS version 20.0. RESULTS:Among 347 vegetable samples examined, 87(25.1%) were contaminated with at least one parasite species. Tomato (35.0%) was the most commonly contaminated vegetable while green pepper (10.6%) was the least contaminated one. Entameoba histolytica/dispar (29, 8.4%) was the commonest parasitic contaminant detected followed by Giardia lamblia (24, 6.9%) and oocyst of Cryptosporidium species (5.8%). Vegetable type (X2 = 13.5; p = 0.009) and source of vegetables (X2 = 24.1; p < 0.001) were significantly associated with parasitic contamination of vegetables. CONCLUSION:Parasitic contamination rate among marketed vegetables in the present study is significantly considerable. Entameoba histolytica /dispar was the most frequently detected parasite. We recommend to the local public health sector to establish a system for continuous monitoring of contamination of vegetables sold at local markets.
