ABSTRACT

Milk has been known to be highly nutritive ad thus a good medium for bacteria growth and vehicles for transmission of food borne infection. A total of 16 samples of different brands of bagged milk obtained from some selected markets within Kaduna metropolis were analyzed for the occurrence of bacteria using pour plate method on selective media. The total aerobic count ranged from 4.0 x 103 to 2.8 x 106. The result obtained showed that bacteria (Staphylococcus aureus) in bagged milk are within the tolerable level as specified by World Health Organization. The public health significance of Staphylococcus aureus in food is highlighted.
