Fruits and vegetables are sources of parasitic infections in humans. This study was designed to determine the epidemiology of parasitic contamination of fruits, vegetables, and water, as well as the perception of retailers, buyers, and consumers about its contamination in Kwara Central, Nigeria. A cross-sectional study design was employed for this study. A total of 160 fruits, 349 vegetables, and 51 water samples were randomly purchased/collected from thirty different markets. The samples were subjected to sedimentation and modified Ziehl-Neelsen staining techniques. All the types of fruits and vegetables sampled were contaminated with one or more parasites. Eleven different species of zoonotic parasites (6 protozoans and 5 helminths) were detected. Entamoeba coli (39.8%) and Strongyloides stercoralis (9.6%) were the most prevalent protozoan and helminth respectively. The prevalence of other protozoan parasites ranged between 21.3% (Entamoeba histolytica) and 2.3% (Balantidium coli), while that of helminths was between 5.7% (Ascaris lumbricoides) and 2.1% (Trichuris trichiura). Source of fruits and vegetables, source of manure for cultivation, the source of water for washing/wetting purpose, market type, washing of fruits and vegetables before display, the presence of children at home and in the market, and knowledge of parasitic contamination were the risk factors associated (P<0.05) with parasitic contamination of fruits and vegetables among sellers. There is a need to educate the general public on the possibilities of parasitic contamination of fruits and vegetables and its public health implications.
