Abstract
This study evaluated the microbial safety of vended boiled, pasteurized and UHT milk sold in Nakawa, Kampala-Uganda. 15 milk samples were analyzed; 2 samples had Salmonella, 5 had S. aureus with a count of 1.66 0.02 log10CFU/ml. E. coli was detected in 8 samples with 1.0 0.02 to 3.0 0.01log10CFU/ml count. A high load of 3.0 CFU/ml was obtained in 3 samples with E. coli. Four E. coli positive samples had a contamination load of 2.0 0.015log10 CFU/ml of which one was pasteurized milk. Only a pasteurized milk showed a low E. coli load at 1.0 0.02log10 CFU/ml. All UHT milk had no microbial contamination. Both boiled and pasteurized milk had Salmonella,S. aureus and E. coli in levels above the set threshold limits. Milk consumers in Nakawa stand a potential public health risk of food poisoning reflected by presence of Salmonella, S. aureus and E. coli in some milk sold in the area.
