The microbiological qualities and physicochemical properties of fresh fruits (water lemon. orange, pineapple and apple) juice were investigated using standard methods. The juices were stored at 30 oC�?±1 from day 0 to day 20. The bacteria isolated were Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Azotobacter chroococcum, Erwinia amylovora, Acinetobacter calcoaceticus, and the yeasts Saccharomyces cerevisiae, Pichia membranifaciens. The total viable bacterial count orange juice ranged from 5�?�?106-1.16�?�?108 cfu/ml, water melon 2�?�?106-1.27�?�?108 cfu/ml, pineapple 7�?�?106-1.04�?�?108 cfu/ml and apple ranged from 6�?�?106-2.6�?�?107 cfu/ml. The fungal counts of orange ranged from 0�?�?102-182�?�?102 sfu/ml, water melon 0�?�?102-76�?�?102 sfu/ml, pineapple 0.0�?�?102 l -182�?�?102 sfu/ml and apple 0.0�?�?102 -118�?�?102 sfu/ml. The total viable counts of bacteria in all the fruits juice decreased with increase in fungal counts. Titratable acidity increased with the decrease in pH while other nutrients in the fruits juice also decreased. Juice obtained from fresh fruits contained microbes which potentially is hazardous to public health.
