| dc.description.abstract | Vegetables play an essential role for good health and they form a major component of human diet, but raw and minimally processed vegetables also serve as main agents of intestinal parasitic diseases. Vegetables get contaminated with these parasites throughout the process of planting to consumption. During the present study, vegetable samples of tomato, capsicum and cucumber collected from different polyhouses and open fields at Punjab Agricultural University and at local markets near P.A.U gate no. 3 and from the sources of contamination i.e. pre-harvest (irrigation water and soil) and post harvest (reservoir tank water) sources were processed and helminthic parasites (eggs/larvae) were extracted. Vegetables were found to be significantly less contaminated in polyhouses than in open fields and local markets. The helminthic parasitic incidence was found to be more in winter than in summer season. The maximum helminthic infestation during winter season in tomatoes from local markets was 58.33% followed by open fields (33.33%) and least in polyhouses (25%). In polyhouses, three types of parasitic helminths were found from samples of cucumber, capsicum and tomato and these were: Ascarid eggs, Strongyloides stercoralis (larvae) and Trichuris trichiura. Two more types of parasites were observed in the open fields these were: Fasciola spp. and Ancyclostoma duodenale. Four types of helminth parasites were found in local markets nearby PAU these were Ascarid eggs, S. stercoralis, T. trichiura and Fasciola spp. S. Stercoralis was the most prevalent helminth parasite >Ascarid eggs >T. trichuira >Ancyclostoma duodenale and Fasciola spp. was the least in tomato, cucumber and capsicum samples collected from polyhouses and open fields at P.A.U and local markets nearby P.A.U. | en_US |
