Abstract: Current study emphasized on assessing the pesticide residue level in common edible fish Channa sp. followed by its health risk assessment. Kattemalalavadi of Hunsur Taluk is a remote area with intensive farming activity. Tributary of Cauvery, Lakshmana Teertha flows through Kattemalalavadi hobali encouraging fishing activities. Fishes like Tilapia, Common Carp, Rohu and Channa are commonly captured and sold in local markets. Agricultural rundown is adding pesticides and heavy metals to these water bodies. Hence in the current study fish Channa was selected to assess levels of two pesticides Aldrin and Dieldrin in muscle tissue. The data thus obtained was used for health risk assessment in random population. Pesticide analysis was done by GC-MS/MS, using FSSAI Manual test method. Details about fish consumption was collected using Questionnaire with a sample size of 200 to assess the health risk, EDI, Hazard quotient (HI) and Cancer risk. Hazard quotient and cancer risk value for both Aldrin and dieldrin in Channa sp, is found to be within low risk level at thirty four gram per day consumption rate in the study area.
