Abstract [en]

As the wild boar population increases, so does the consuming of wild boar meat. Often with the belief that this is much healthier than conventional meat. International studies have shown that wild boar meat is more likely to contain higher concentrations of soil pollutions than other game meat. The aim of this study was therefore to analyze the concentrations of lead (Pb) and cadmium (Cd) in the liver of free living wild boars (Sus scrofa), located in the south of Sweden. Samples were taken from 10 wild boars during the hunting season of spring, 2018. The lead and cadmium concentrations in wild boar livers were determined by AAS- atomic absorption spectroscopy. Our result shows a higher uptake for cadmium than lead. Cadmium also seem to increase with age in wild boars due to bioaccumulation. However, 7 out of 10 livers exceeded the maximum limit for food safety standards regarding lead (0,10 mg/kg) and 2 out of 10 for cadmium (0,50 mg/kg). Therefore, the consumer should practice vigilance, especially for wild boar meat originating from areas known to be contaminated.
