The hygienic quality of raw reindeer milk
The somatic cell count (SCC) and total bacterial count (TBC) as well as the presence of major food-borne pathogens and udder pathogens in reindeer raw milk were studied. Two groups of 4 female reindeer were milked on alternate days for six weeks. A milk sample from each quarter was taken before milk...
