“…This is in agreement with literature data, in which a tendency for decreasing mercury concentrations in animal tissues has been documented (Falandysz 1993;López-Alonso et al 2007). In the most recent study, Nawrocka et al (2020) did not confirm the decreasing trends of Hg concentrations in pig's liver from 2009 to 2018, although their values were lower than those reported by other authors from Poland in previous decades.…”

The assessment of mercury content in the muscle, liver and kidneys of fattening pigs and sows was conducted in the Czech Republic during the period of 2015–2019. The samples were collected from sows (n = 31) and fattening pigs (n = 210). The average mercury content in muscle, liver, and kidneys of sows over 5 years was 0.00057 ± 0.00004, 0.0045 ± 0.0008, and 0.0224 ± 0.0067 mg·kg-1, respectively. The average mercury content in muscle, liver, and kidneys of fattening pigs over the same period was 0.00059 ± 0.00004, 0.0012 ± 0.0001, and 0.0044 ± 0.0004 mg·kg-1, respectively. The maximum residual limit (MRL) for human consumption was exceeded in 14 kidney samples. The mercury content in liver did not differ significantly between sows and fattening pigs; in kidneys, the mercury content was higher in sows, with a significant difference in one year (P < 0.05). A slight decrease in the mercury content in kidneys and liver was observed in fattening pigs from the year 2015. In sows, there was a significant increase in the mercury content in kidneys in the year 2016. It can be concluded that there is a need for further monitoring of the mercury content in pig tissues in the Czech Republic.

“…Macrofungi are important food for animals, including insects, snails, rodents, deer and wild boars and the fungal spores can account for up to 35% of their stomach volume (Nawrocka et al 2020 ). Wild-growing mushrooms are also a popular component of the human diet, especially in Poland, which is also the second-largest producer of mushrooms in Europe.…”

“…The assessment of THg concentration in the muscle and liver of cattle and pigs carried out on behalf of the Polish government in 2009–2018 showed that only 0.4% of results were not acceptable. Therefore, the consumption of the meat of slaughter animals does not pose a significant threat to the health of consumers (Nawrocka et al 2020 ). Probably due to the non-hazardous THg level in the Polish livestock, the Hg speciation was not examined.…”

The goal of this paper is to assess the current status and trends of total mercury (THg) contamination of the atmosphere and terrestrial ecosystems in Poland. The study shows that the reduced domestic and worldwide atmospheric emission of Hg resulted in decreased THg level in the terrestrial biotope and biosphere. Considering that Poland is one of the main Hg emitters in Europe, the THg concentrations in its abiotic environment are still elevated. However, the THg level in terrestrial organisms is relatively low, which is because a large proportion of Hg deposited on land is accumulated in organic-rich soils. Regarding the THg concentration, consumption of wildlife and livestock from Poland is safe for humans. Nevertheless, the authors indicate the need for effective environmental monitoring, based on selected bioindicators, which is crucial considering the slowing reduction of Hg emission combined with the consequences of the changing climate.

“…However, many challenges remain in understanding the dynamics of these elements from the animal/farm to the consumer to produce profitable but sustainable farms and thus accurately determining the possible short, medium and long-term impacts. Some aspects of animal production, such as breed and physiological state [ 19 , 20 ], antagonism between elements [ 21 ], productive practices adopted in livestock [ 22 ] and air quality and environmental quality in general [ 23 , 24 , 25 ], can have significant impacts on the concentrations and accumulation of these elements in animal tissues. The precise management of these elements in animal production is not an easy task, particularly in extensive production systems, due to the existence of a wide variety of environments, diversity of management practices, complex interactions between elements and biochemical processes and the occurrence of natural and anthropogenic changes in the environment [ 7 , 26 , 27 ].…”

The objective was to investigate the context, approach and research topics present in the papers that analysed trace elements in beef cattle to identify gaps and scientific perspectives for the sustainable management of trace elements in livestock. The main research groups came from the United States, Spain, Japan, Brazil, India and Slovakia, which represented 31% of the papers produced. Only 37% of studies addressed aspects that integrated animal, environmental and human health. The reviewed papers concerned 56 elements and 15 bovine tissues (Cu, Zn, Pb, liver, muscle and kidney highlighted). The main gaps were (1) lack of research in developing countries, (2) the need to understand the impact of different environmental issues and their relationship to the conditions in which animals are raised, and (3) the need to understand the role of many trace elements in animal nutrition and their relationship to environmental and human health. Finally, we highlight possible ways to expand knowledge and provide innovations for broad emerging issues, primarily through expanding collaborative research networks. In this context, we suggest the adoption of the One Health approach for planning further research on trace elements in livestock. Moreover, the One Health approach should also be considered for managers and politicians for a sustainable environmental care and food safety.
