Abstract

The potential presence of toxic metals in food is being recognized as a priority by standards organizations and constitutes an analytical challenge. The toxic metal content of milk and dairy products is due to several factors: environmental conditions, the manufacturing process and the possible contamination during several steps of the manufacturing processes. The aim of this study was to evaluate samples of raw milk with fat contents 3.8% obtained at randomly from animal farms in around Nitra, western Slovakia region and ultra – heat treated cow milk (UHT) with fat contents 1.5% commercially available from local market in Nitra. Samples of milk were analysed for metal contents using atomic absorption spectrophotometry (AAS). UHT milk showed higher levels of cadmium, nickel and iron. Higher levels of zinc, copper were detected in raw milk. Significant differences in the concentration of copper between raw and UHT cow milk were found.
