Samples of animal raw materials were obtained in 2013 in the municipalities of Porac and Matejovce nad Hornádom. Samples of muscle and internal organs were collected from domestic sheep (Ovis aries) reared in the village of Rudnianska burdened area where mercury along with other heavy metals contamination is above the limit value of agricultural soil. Measuring the concentration of heavy metals in the samples was performed in accordance with the general requirements set out in the tenth chapter of the Food Code of the Slovak Republic. Mercury content in biological materials were assessed by total mercury as on the AMA 254 in fresh samples. The other heavy metal content, was determined after wet mineralization (HNO3: H2O - 1: 1) using the device AAS Varian 240 FS. The contamination of the environment showed increased accumulation of heavy metals in the - studiet sheep tissues intended for consumption. Such as Hg content in the kidneys of domestic sheep exceed the limit value by 1.3 times, whereas, in the case of cadmium 3 times exceeding the limit value in meat was recordered. Exceed limit was recorded in the case of lead and copper in the liver.
