Prevalence of Parasitic contamination of salad vegetables in Ilorin, North Central, Nigeria
Abstract
Fresh salad vegetables are essential for good health and they form a major component of human diet in every family in Nigeria. Raw vegetables can be agent of transmission of intestinal parasites. The aim of this study is to determine the parasitic contamination of salad vegetables sold at wholesale and retail markets around Ilorin metropolis. A total of 150 samples of salad vegetables obtained from five different markets were examined for both protozoa and helminth parasites using standard methods. About 25 samples each of lettuce, cabbage, carrot, cucumber, tomato and onion were examined. Eggs of Ascaris lumbricoides, Entamoeba histolytica/dispar, Enterobius vermicularis, cysts of Giardia lamblia, Fasciola hepatica, Trichuris trichiura, Strongyloides stercoralis, Balantidium coli and Necator americanus were detected in 28.0%, 23.3%, 11.7%, 5.0%, 6.7%, 3.3%, 10.0%, 3.3% and 8.3% respectively. Of the sampled areas, Ipata market recorded the highest parasite prevalence of 63.3% while G.R.A market recorded the lowest parasite prevalence of 13.3%. The most encountered parasite was A.lumbricoides (28.0%) while N.americanus was the least (3.3%) parasite found. The study revealed a high rate of protozoa and helminthes contamination of salad vegetables in the study areas. Parasitological contamination of raw salad vegetables sold in wholesale and retail markets in the study area may pose a health risk to consumers of such products.
