Evidence of Transmissible forms of Enteroparasites on Leafy Vegetables Commercially Traded in Selected Markets within Makurdi Metropolis, Benue State, Nigeria

Abstract

Enteroparasitic infections are known to cause a lot of morbidity and socio-economic deprivations in developing countries with poor sanitary conditions. This work evaluated the prevalence of transmissible forms of  enteroparasite on vegetables sold at four different markets in Makurdi, Benue State, Nigeria. Two-hundred and forty vegetable samples were obtained from four (4) varieties using a randomized design. Samples were examined using concentration technique. The result showed prevalence of 42.4% of enteroparasites. Telfaria occidentalis (flutted pumpkin) recorded the highest prevalence rate of 61.7%, whereas the least infestation was seen in Amaranthus hybridis (Spinach) 25.0%. Entamoeba histolytica (20.0%) was the most common protozoan parasite implicated while Ascaris
lumbricoides (45%) was the most common helminth. Statistical analysis showed a significant association between enteroparasites and vegetables (p<0.05, df = 3, x2 = 11.8). Results of the study showed a great potential risk of acquiring enteroparasite through the consumption of raw or  minimally cooked vegetables. The need for proper washing and cooking of vegetables therefore cannot be overstated.

Key Words: Enteroparasites, Telfaria occidentalis, Amaranthus hybridis, Entamoeba histolytica and Ascaris lumbricoides.
