ABSTRACT (Download PDF)

vegetables sold in Nkpor Market, Ochanja Market and Ose Market all in Onitsha, Anambra State
between July and August, 2014. These vegetables were procured directly from the rural farmers
who brought the vegetables to the markets. They were examined in the laboratory for the
presence of parasites using floatation and sedimentation techniques. Out of 480 vegetables
specimens examined, 210 were contaminated thus giving a total prevalence of 43.8%.The
parasites isolated were Ascarislumbricoides120(57.1%), Entamoebahistolytica 30(14.3%),
Hookworm 45(21.4%) and Strongyloidesstercoralis15(7.1%). The highest parasite
contamination was found in fluted pumpkin 43(20.5%) and the least on okro 11(5.2%) and carrot
11(5.2%). Ose market (53.1%) has the highest occurrence of parasite and Nkpor market (31.3%)
had the least. These findings may have important implications for global food safety and
emphasize the importance of raw vegetables in threatening public health by transmission of
intestinal parasites to humans in Nigeria. Individuals and local health authorities should improve
the sanitary conditions in the areas where the vegetables are cultivated and consumed. Therefore,
proper treatment of wastewater used for irrigation of vegetables and improvement of sanitary
facilities in our markets and among vegetable vendors are recommended.
