Contaminants like heavy metals could remain in milk and its by-products if forage used for ruminant nutrition is contaminated with high levels of these elements. In EU maximum levels (LMR)are established only for lead in milk. In Russia limits have been fixed for different heavy metals in milk and dairy products; for this reason exporting countries, including Italy, have to demonstrate the conformity of their products to the expected limits. IZSPLV analysed 18 cheese samples to research lead, cadmium, arsenic and mercury. All samples were negative and could be exported toRussia.
