Sobo drinks retailed within Ilorin metropolis were investigated for their bacteriological quality, in terms of the total bacterial count and types of bacterial species present. The sobo drinks were found to have an average pH of 3.2. The bacterial counts were generally high ranging from 5.0×104 to 24×104 CFU/ml. Six bacterial species; Bacillus subtilis, Staphylococcus aureus, Streptococcus faecalis, Klebsiella spp, Enterobacter spp, and Escherichia coli were isolated. Consideration of the distribution pattern showed that samples from Unilorin Main Campus and General Post Office contained all the isolates, while three of the isolates; Escherichia coli, Bacillus subtilis and Staphylococcus aureus were common to all samples. Possible sources of the contaminants and their public health implications are discussed and suggestions offered on ways of ensuring safety of the sobo drinks.
