Content of essential and non-essential elements in wild animals from western Ukraine and the health risks associated with meat and liver consumption

The meat and offal from game animals may act as sources of both essential and non-essential elements and the presence of high levels of toxic elements in their tissues can pose a serious threat to human health. The purpose of the work was to determine the levels of selected toxic and non-toxic elements in the tissues of free-living animals from western Ukraine and to assess the health risks associated with meat and liver consumption. The test material comprised muscle, liver and kidney samples taken from 12 wild boar (Sus scrofa), 10 roe deer (Capreolus capreolus), 8 hares (Lepus europaeus L.). All material was obtained from the Lviv region, western Ukraine. The obtained results indicate the presence of a relatively high Pb content in free-living animals in western Ukraine. The permissible concentration of this element was exceeded in all meat and offal samples. In the case of Cd, exceeded permissible values were observed in the muscle of wild boar (30% of samples) and kidney of wild boar (8% of samples), roe deer (20% of samples) and brown hare (12% of samples). The highest HQ values were observed for Fe, Cd, Zn and Mn in the consumed liver and meat of the tested animals. However, in neither case was the HQ or HI found to be greater than 1, which indicates a low probability of the development of adverse health effects associated with the consumption of game.
