Milk makes a significant contribution to the human diet through provision of macro nutrient, vitamins and minerals. The exact composition of milk varies by species to naturally or contamination. It is recognized that imbalance quantity of minerals and trace element being a serious health hazards especially for infants. Therefore, some essentials elements like  K, Fe, Co and Pb (as a non essential element) have been determined in locally available milk powder of infant formulas, milk powder of growing children , processed milk or tetra pack milk of different brands and fresh milk samples (cow and buffalo) by sophisticated analytical techniques flame emissions spectroscopy (FES) and atomic absorption spectroscopy (AAS). The range of mean concentration of elements (K, Fe and Co) in milk samples was found to be 650.00-1500.00mg/l, 2.76-8.93mg/l and 0.05mg/l respectively. The levels of these elements in milk powder of infant formulas (1&2) were compared with the standards of FAO/WHO, recommended values of the Committee on Nutrition of the American Academy of Pediatrics, human milk and cow’s milk.
