In developing countries, including Pakistan, irrigation system of crop is achieved using untreated waste water and domestic animal raw compost as fertilizer. Hence, vegetables are considered to be the primary sources of human infection with, protozoan, bacterial and helminthes parasites. There for the aim of this study is to in investigates the prevalence of pathogenic bacteria and enteric parasite in waste water irrigated vegetables of Suburb city, Quetta and and coli form Bacteria in irrigated waste water. In this study 20 waste water and 150 different leafy vegetables including spinach, tarteeza , manthali, salad , coreder, janboo, nustured, mint, green onion were examined for bacterial and parasitic examination. Out of 150 leafy vegetables 45(30%) samples were contaminated with Giardia lambia, 16 (10.6%) Tape Worms, 3 (2.0 %) Hook worms, 10 (6.6 %) Round Worms, 15(10%) Coccidia Lamae, 3(2.0%) Pin worms, 9(6 %) Adult lung worms, 3 (2 %) Whip Worms, 1(0.6%), E. Histolytica, 1 (0.6%) Camillid Cappilaria, 3 (2.0 %) Entomoeba Coli, 7 (4.6%) Intestinal Fluke, 1(0.6%) Stomach Worms, 1( 0.6%) Lubricoide Surface Focus. ). Jambo ( 50%) was the most frequently contaminated vegetable followed by Mint (45), Spinach ( 44%), Salad ( 37%), Tarteezak( 33%), Corrode (25%), Green Onion ( 22%) while Mathly and Nustard (Sarsun) significantly show less contamaniation . Total 20 wastewater samples were analyzed. Out of 20 sample , 12( 60%) were detected coliform bacteria and 8(30%) E.coli bacteria. In this present study, waste water coliform composition ranged from 4.5 to 1.2 log with an average of 2.7 log CFU/100 ml, while E.coli ranged from 3.0 to 1.5 log CFU/100 ml with a mean of 1.9 log, in wastewater.
