Although it is well established that meat and meat products provide essential nutrients for human development and health, inadequate or inappropriate consumption of these foods can also lead to various health problems. Moreover, in 2015, the IARC classified the consumption of red meat and processed meat as "probably carcinogenic to humans" and as "carcinogenic to humans," respectively. However, the exposure to environmental (organic and inorganic) contaminants through the consumption of meat and meat products was not then discussed. In this paper, the recent scientific literature on human exposure to metals and metalloids through the consumption of meat and meat products has been reviewed, with a main focus on toxic metals and metalloids such as As, Cd, Hg, and Pb. According to PubMed and Scopus, Asia is the continent for which the most data have been reported since 2000, with China specifically being the country with the highest number of available papers on the topic of the present review. Therefore, this review has been focused only on Asian countries. As expected, the concentrations of metals and metalloids in meat and meat products, as well as the estimated intake derived from that consumption, have shown notable differences among regions and countries. However, as has also been previously observed for organic pollutants, the group of meat and meat products is not being, at least in Asian countries, one of the most relevant food groups contributing to human dietary exposure to toxic metals and metalloids.

IntroductionThe level of essential minerals in meat is an important factor in human nutrition and health. Meat from responsibly managed wildlife is an alternative raw material with considerable nutritional benefits. Meat from hunted animals has essential and non-essential elements for the human body. It is important to carefully monitor the levels of heavy metals accumulated in the tissues of hunted animals in polluted areas to ensure food safety and environmental contamination. High levels of heavy metals in food and the environment can pose a danger to human health.MethodsThe study aims to investigate the levels of essential mineral elements and heavy metals in the muscle tissue and organs of wild boar harvested through the herd density control plan over the last decade in north-eastern Romania.Results and discussionThe statistical analysis indicates that the age of the animals had a significant impact on Fe, Cu, and Zn levels in Longissimus lumborum. In the kidney a highly significant difference in Fe content by sex, with males showing higher values than females. The sex was shown to significantly influence the Mg levels. However, there are concerns about the accumulation of heavy metals such as Lead (Pb) and Cadmium (Cd), which may hurt the health of game meat consumers in the study area. Cd level it shows significant differences according to both age and sex, with higher concentrations in adults and males. Statistical analysis shows a negative correlation between Fe and Zn concentrations in muscle samples, while a positive correlation was found between Fe and Mn in kidney samples. There was also a positive association between Zn and Cu in muscle samples, but a negative association in kidney samples. Principal component analysis shows significant variation in essential element and heavy metals data between muscle and kidney samples. The loading plot shows a direct correlation between Pb and Cu and between Pb and Cd. However, an opposite correlation also is observed between Cu and Mg, Cd and Mg, and Pb and Mg. HQ (Hazard Quotient) for children compared to adults indicates a potentially higher risk associated with meat consumption among children because children are more vulnerable than adults. We report for the first time, to the best authors’ knowledge, various levels of essential minerals and exceeded maximum admitted level of heavy metals in the muscle tissues and kidneys of Sus scrofa ferus from Romania intended for human consumption, moreover, our findings highlight the need for strict monitoring and implementation of appropriate corrective measures, given the significant percentages of muscle and kidney samples exceeding the allowable limits for two of the most common toxic metals in the environment.
