Large game animals (roe deer, red deer and wild boars) were harvested in hunting grounds located in the Warmia and Mazury District (Poland). Blood samples were collected (from the heart or jugular vein) immediately after the animals had been shot. Plasma was separated from whole blood to determine the levels of zearalenon (ZEA) and alpha-zearalenol (alpha-ZOL). ZEA and alpha-ZOL were found in all animal species examined in the study. The highest concentrations of these mycotoxins were recorded in wild boars. The lowest amounts of these compounds were observed in young wild boars (weaners), and the largest - in the oldest ones. The presence of both forms of mycotoxins in the blood samples of game animals indicates that their feeding grounds, such as crop fields, are infested with mould fungi (mainly of the genera Fusarium and Penicillium). Such a high percentage of animals (especially wild boars) whose blood contains mycotoxins constitutes a serious health hazard to wild game consumers
