GEOHELMINTHS CONTAMINATION OF LEAFY VEGETABLES SOLD AT SELECTED MARKETS IN YENAGOA METROPOLIS, BAYELSA STATE, NIGERIA

ABSTRACT This study investigated the contamination of leafy vegetables with geohelminths in selected markets within Yenagoa metropolis, Bayelsa State, Nigeria. Leafy vegetables are widely consumed for their nutritional benefits; however, they may serve as vehicles for the transmission of intestinal parasites when contaminated. A total of (insert number) vegetable samples, including fluted pumpkin (Telfairia occidentalis), waterleaf (Talinum triangulare), and scent leaf (Ocimum gratissimum), were collected from major markets and analyzed using standard parasitological techniques such as sedimentation and flotation methods. The results revealed the presence of geohelminth eggs and larvae, including Ascaris lumbricoides, Trichuris trichiura, and hookworm species. The overall contamination rate was (insert %), with higher prevalence observed in vegetables obtained from open markets with poor sanitary conditions. Factors such as the use of untreated wastewater for irrigation, unhygienic handling, and poor market sanitation contributed significantly to contamination levels. The study highlights the public health risks associated with the consumption of raw or poorly washed vegetables. It recommends improved hygiene practices, proper washing of vegetables before consumption, and stricter monitoring of agricultural and market sanitation standards to reduce the transmission of geohelminth infections.
