Eight (8) samples of packaged fruit juice which include mango, peach, orange, strawberry, apple, apple/mango, pineapple and orange juice were analyzed for the presence bacterial pathogens using standard microbiological techniques. These fruit juices were purchased from retail shops in Bauchi metropolis, Nigeria. Total bacterial cell count of some of the packaged fruit juice sample ranges from 3.8 x 104 cfu/ml (for mango juice), 1.1 x 105 cfu/ml (for peach juice), 2.5 x 104 (for orange and orange 2 juice), 2.9 x 104 (for strawberry juice) 2.0 x 104 (for apple juice) and 5.0 x 104 for (apple/mango fruit juice. Bacteria isolates obtained from the packed fruit juice includes; Staphylococcus aureus (30%), Pseudomonas aeruginosa (30%), Klebsiella spp (20%) and Escherichia coli (20%). Antibiotic susceptibility testing of the isolates showed that many of the bacteria had an intermediate, resistant and sensitive reaction to most of the antibiotics tested. The bacterial species isolated were 80% sensitive to ciprofloxacin (5µg), 70% sensitive to amoxicillin (25µg) while it showed a 70% resistance pattern to tetracycline(30µg), 60% resistance to ceftazidime(30µg). Some showed intermediate sensitivity to gentamicin (10µg). Due to the number and types of bacteria isolated from the different packaged fruit juices, it can be concluded that bacteria are present within fruits and the materials used for the production of the juice, as well as poor sanitary condition, raw material contaminations, lack of both proper heat sterilization and adequate quality control during processing of fruit juice could be the reasons for this contamination
