The bioaccumulation of mercury (Hg) in the food chain may pose a threat to human health. The risk of dietary Hg intake is mostly caused by the consumption of fish and seafood, therefore the knowledge on the exposure from land animal products is limited. In our article, we summarized the results of analyses of Hg in muscle tissue and liver of different livestock and game animals obtained during ten years of official monitoring that was carried out in Poland from 2009 to 2018. The majority of the results in muscle tissue were below the limits of quantification (LOQs). The mean Hg concentrations in muscle tissue ranged from 0.6 to 5.6 μg kg -1 of wet weight and the mean liver Hg concentrations were within the range of 0.8-16.4 μg kg -1 of wet weight, with lowest levels in chickens and highest in wild boars. The results revealed decreasing trends in liver Hg in cattle and cervids over the years, which was congruous with decreasing emission of Hg in Europe. Our results showed that the consumption of meat and liver of livestock and game animals in Poland may be considered to be safe for human health, which was confirmed by the low number of noncompliant samples relative to the applicable legal limits, as well as by estimated dietary exposure., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 The Authors.
