ACCUMULATION OF SOME HEAVY METALS (PD, CD AND CR) IN MILK OF GRAZING SHEEP IN NORTH-EAST HUNGARY

摘要

Food safety and traceability control in the production of agricultural primary products becomes more important criteria for the consumers because of the novel requirements of foods as tools for disease prevention and health. The objective of this study was to investigate the accumulation of lead, cadmium and chromium in milk of ewes during pasture condition. In present study, the amounts of the heavy metals in grass samples were lower than the highest acceptable limits according the regulations. Moreover, lead, cadmium and chromium concentrations were 0.023 mg, 0.012 mg and 0.290 mg/wet weight kg in milk samples, respectively. 50% and 40% of the milk samples the lead and cadmium values were out of the permissible limit. However, the amount of the heavy metals in grass and other forages samples were lower than the highest acceptable limits, concentration of Pb and Cd in milk samples were higher than the maximum acceptable limits of the EU regulation. These results suggested that necessary control the heavy metal contents of primary food products for food safety.
