Abstract : In the course of a study of parasitic infections by cyst and ova on fruits and vegetable sold in middle-belt Nigeria, three different major public markets was selected. Six different fruits and vegetables total to 2406 samples were examined.Data obtained were statistically analyzed using anova for the level of significance difference where appropriate. Of the 1755 fruits examined, 4.3% were positive for parasites ova and 2.5% for cysts. Of the 761 vegetables examined, 4.6% were positive for parasites ova and 2.8% for cysts.The contamination rate of protozoan cyst and ova found are Giardia lamblia (2.61%) Entamoebs histolytica (0.66%). The difference was not statistically significant (p>0.05).Cases of contamination rate of protozoan cyst and ova were small compared to helminthic contamination. However, helminths such as Strongylodies stercoralis Trichiuris trachura and Ascaris lumbricoides were predominant in that order. The public health implication on the subjects is discussed. Through washing of all fruits and vegetables with clean water prior to consumption is recommended.
