Аннотація: In the conditions of technogenic load on the environment, one of the priority areas is the monitoring of heavy metals in the trophic chain: «soil → plant (feed) → animal → product → human». In order to prevent poisoning of agricultural animals with heavy metals, it is recommended to systematically monitor the presence of toxic metals in the feed ration. Of particular concern is the production of poultry meat at home, where it has free access to natural minerals, most of which contain heavy metals and other toxicants. Based on this, there is a need for constant monitoring of the contamination of the fodder base of poultry kept at home and the use of control measures to increase the safety of domestic products. The content of heavy metals in meat is one of the most important sanitary indicators of its safety in conditions of contamination of feed with heavy metals. to improve the sanitary safety of poultry products by the level of cadmium and lead. For the correct organization of poultry feeding, it is necessary to take into account, first of all, the nutritional value of feed and its quality. The basis of the ration of agricultural poultry is grain feed (55–80% of the ration), which is part of compound feed. In order to control feed safety, it is necessary to conduct monitoring at all stages of production: starting with the production of raw materials and components, their further processing, storage, transportation and before use. A soil sample taken in the conditions of the Right Bank Forest-Steppe of Ukraine was studied and analyzed, and an excess of the MPC in it and vegetative mass for cadmium by 1.28 and 1.5 times, respectively. barley, corn and sunflower meal. At the same time, exceedances of maximum permissible concentrations were investigated. In particular, in wheat grain, which, among the concentrated feeds of poultry kept at home, makes up 55% on average, an excess of cadmium and copper was found by 2.1 times and 2.0 times, respectively. An excess of the maximum permissible concentrations by 3.0 times was also observed in sunflower meal. The lowest level of heavy metals such as lead, cadmium, zinc and copper was observed in corn grain.
