Several parasitic infections are associated with poor hygiene and environmental sanitation resulting in food and watercontaining ova, cysts or larva of these parasites. Therefore, a survey of fruits and vegetables sold at some major markets in Ibadan was carried out between January and June, 2011 to identify the ova, cyst and larva present on them. A total of 264 fruits and vegetables pieces were examined using standard wet mount procedure and Kinyoun acid fast stain to detect parasites. The percentage of fruits and vegetables with eggs, cysts or larvae of eight different species of parasites encoun-tered were 38.09%, 20.38%, 18.56%, 8.33%, 6.42, 4.55%, 2.15% and 1.67% for Ascaris lumbricoides eggs, Strongyloides stercoralis larvae, hookworm eggs, Oocysts of Cryptosporidium, immature cyst of Entamoeba histolytica/dispar, trichuristrichuira eggs, Taenia species egg and oocyst of Isospora species respectively. Tomatoes had the highest percentage with parasites-ova, cysts or larva (73.33%) followed by Irvingia and carrots (66.7% each), mangoes (58.33 %), garden eggs(43.35%), cherries (33.33%), oranges (25.0%), cucumber (22.22%) and lime (12.5%). Considering the availability of different fruits at different seasons of the year and the present-day back to nature‚ approach to healthy diet, it is pertinent to encourage proper washing of fresh and raw fruits and vegetables before they are sold or eaten, thereby preventing transmission either at point of sell or consumption of fruits and vegetables which form sources of infection via the oral route.
