Nine minerals (calcium (Ca), magnesium (Mg), sodium (Na), potassium (K), phosphorus (P), zinc (Zn), iron (Fe), copper (Cu) and manganese (Mn)) have been estimated in milk of three different species namely, cow (Sahiwal and Tharparkar), buffalo (Murrah) and goat (Alpine x Beetle) of India. Among the species studied, buffalo milk had the highest Ca, P and Mg contents. Na content was found lowest in buffalo milk and K was found significantly higher in goat milk. K was the major mineral in cow and goat milk while Ca was major mineral in buffalo milk. Mineral distribution data indicated that colloidal minerals were highest in buffalo milk followed by goat and cow milk. Ca to P ratio was found maximum in buffalo milk (1.74) and was almost similar in milk (1.45-1.49) of other species studied. Our study indicated that 500 g of milk can meet more than 60% recommended daily allowances of Ca and P as recommended by Institute of Medicine,

Milk and milk products are a significant part of healthy diet. However, contamination of milk can be dangerous and detrimental for the health of consumers. The safety of milk and milk products decreases with increasing concentration of toxic compounds and environmental pollutants. The study was aimed to investigate the contents of some heavy metals in 30 samples of commercially available milk and milk products (dahi, cheese, paneer, khoa and milk powder) collected from five different vendors, from Karnal district of Haryana (India) to know whether the intakes comply with the permissible levels for toxic elements. Mean concentration of all the heavy metals analyzed showed a range of 3. 38-26.4, 3.16-13.89, 3.77-21.04 and 3.34-10.68 ppb for cadmium, lead, arsenic and mercury, respectively. Results indicated that the content of cadmium was maximum in all the samples except for paneer, where mercury concentration was maximum.
