Abstract: An attempt was made to know the residual status of some organochlorine pesticides in shrimp (Peneus monodon) and prawn (Macrobrachium rosenbergii) by Electron Capture Detector (ECD) of Gas Chromatography during their culture with rice. A Total of six (06) sites viz. Bagerhat Sadar, Kochua, Fakirhat, Mollarhat of Bagerhat District and Dumuria, Fultola of Khulna District were selected for this study from where the shrimp/prawn samples were collected to assess some organochlorine pesticides named Heptachlor, DDT, Dieldrin and Endrin. The heptachlor residue concentration was 0.035~0.155 ppm, Endrin residue was 0.008~0.020 ppm, Dieldrin residue concentration was 0.003 ppm and DDT residue concentration was 0.005 ppm in Shrimp body. In Prawn sample, Heptachlor residue concentration was 0.586~0.806 ppm, Endrin concentration was 0.044~0.073 ppm. Dieldrin and DDT residue were not detected in Prawn body. From the assessment of these four pesticide residues concentration in Shrimp and Prawn body, it was noticeable that Heptachlor concentration was in alarming level according to acceptable limit of EU. Endrin, Dieldrin and DDT concentration were not in harmful level in accordance with EU acceptable level. So, proper initiatives should take to inhibit the uses of all classes of hazardous pesticides and chemicals for avoiding any health hazard situation to ensure food safety.
