By considering various contaminants in the water body and sediments of the southern Caspian Sea, there is a possibility of excessive bioaccumulation of heavy elements such as lead and cadmium in aquatic animals, including Rutilus kutum. The elements can eventually enter the human body through the food chain and cause some problems. Therefore, the present study eva‎luated the risk of R. kutum consumption in the stand of lead, and cadmium in the southern shores of the Caspian Sea. Thus, Rutilus kutum (n= 30) were collected by a casting net. The muscle tissues of R. kutum were digested according to the acid digestion method and the concentration of lead and cadmium were determined using an atomic absorption spectrometer. Food consumption risk was performed using the method proposed by the US Environmental Protection Agency. The results showed that the levels of lead and cadmium in R. kutum muscle tissue were 0/717±0/053 and 0/42±0/052 mg/kg, respectively. The levels of lead and cadmium exceeded some of the national and international guidelines. Target Hazard Quotient (THQ) for both lead and cadmium were less than one, indicating the absence of health risk. Daily (0/389 and 0/228 for lead and cadmium respectively) and weekly absorption rates (2/725 and 1/596 for lead and cadmium respectively) were lower than the allowable rates provided by the relevant organizations. Adults can consume 0/391 and 0/167 kg/day and children can consume 0/081 and 0/035 kg/day of R. kutum in terms of lead and cadmium, respectively, without any non-carcinogenic effects on their health. As a result, it seems the consumption of R. kutum according to the current rate does not pose a risk to the health of consumers.
