<b>Laboratory Investigation of Intestinal Parasites and Infective Stages in Fruits and Vegetables from Major Markets in Abeokuta, Ogun State, Nigeria</b>

Abstract

ABSTRACT Background: Fruits and vegetables are crucial sources of vitamins and minerals, promoting good health. However, when consumed unclean, they can pose risks, particularly in rural communities of developing countries where intestinal parasitic diseases are endemic, leading to significant economic and public health consequences. Methods: 500 fruit and vegetable samples were collected and washed separately in 10% formal-saline water. The sedimentation method concentrated parasites, which were then examined using a light microscope. Data entry and analysis were performed using SPSS version 21.0. Pearson chi-square was employed to compare the rate of parasitic contamination among different types of fruits and vegetables and assess the association between parasite species and vegetable type. Results: Of the 500 samples, 105 (21.0%) were contaminated with at least one type of parasite. Strongyloides (5.2%) and Ascaris lumbricoides (3.8%) were the most frequently detected parasites, while Hymenolepis diminuta and Trichostrongylus (1.4%) were the least detected. African cherry (80.0%) was the most infested fruit, and Jute mallow (100.0%) was the most infested vegetable. Itoku market had the highest infestation rate (25.0%) of intestinal parasites on fruits and vegetables, while Adatan market had the lowest (17.0%). Parasitic contamination was significantly different among samples (p<0.05). Conclusion: This study's results show a potentially high risk of acquiring parasitic infections from the consumption of raw fruits and vegetables sold in Abeokuta, Ogun State. Growers, sellers, and buyers need to be sensitized to the proper cleaning and handling of the fruits and vegetables. Keyword: Intestinal parasites, Fruits, Vegetables, Markets and Infestation
