Chromium showed a remarkable increase from raw milk to cheese. The high levels may be ascribed to that this chromium is preferentially bound to milk components such as caseins and during the curdling step move mainly in curd. Chromium is used in the leather industry, in inks and in processing of steel, [5]. Near the sampling sites in the Campania region, where the highest levels of this metal were detected, there are some of those types of industries. EU regulations have not yet fixed limits for chromium in milk or in dairy products. However, the mean chromium value observed was lower than the limit established by the Italian National Residues Plan for ovine spleen tissue, which is considered as a bio accumulator of this metal. Our conclusion is that, since chromium concentrations increased in all cheese products examined it would be advisable to establish maximum limits for this compound not only in milk but also in other dairy products.
