Introduction Inorganic or aggregated forms of chemical substances metalloids heavy metals etc. in feed and food represent a severe risk for their longterm toxicological effects. Heavy metals are widely dispersed in the environment. The toxicity induced by excessive levels of some of these elements such as chromium Cr cadmium Cd lead Pb and mercury Hg are well known Llobet . et al. 2003 . The toxic metal content of milk and dairy products is due to several factors - in particular - environmental conditions the manufacturing process and the possible contamination during several steps of the manufacturing processes. Southern Italy with more than sheep represents an important source of income for rural areas of this territory. The milk from sheep is almost entirely used to produce cheese. At present no data are available concerning levels of heavy metal contamination in milk and dairy products from sheep in Calabria and Campania - two regions of southern Italy. The aim of this work was to detect the concentrations of some heavy metals in milk collected from ewes in several farms in Calabria and Campania and to evaluate to what extent these .
