Dairy products, including cheese and butter, have been known all over the world for their usefulinfluence on human health.The concentrations of heavy metals are an important component of safety and quality of dairy products.

Based on results, the concentrations of cadmium in the dairy samples wereranged from of 0.01 to 2.5 mg/kg of dry weight. The THQ values in some samples were higher than one. Comparing risk levels formen, women, and children, the non-carcinogenic levels were within the following order: children >women >men.
