It is one of the oldest man-made foods consumed by all socio-economic groups. This study was carried out to evaluate the bacteriological profiles and investigate the potassium bromated additives in bread from retail outlets in south west Nigeria. Methods: Bread samples homogenates were examined by standard plate count method on different culture media for isolation of Staphylococcus aureus, Esherichia coli, Pseudomonas aeruginosa, Penicillium spp. And Rhizophus spp were also analyzed for the presence of potassium bromate by spectrophotometry. Potassium bromated in the bread samples was quantitively and qualitatively analyzed using spectrometric determination of bromated in bread. Results: All the 10 samples were found to contain bacteria and molds in varied proportions. Average counts of the isolates for both packed and unpacked bread samples; Staphylococcus aureus,(2.6× 104cfu/g): (4.0× 105cfu/g), Escherichia coli 1.08× 103cfu/g : 1.66× 105cfu/ ) Pseudomonas aeruginosa ( 0.79× 102cfu/g): (1.40× 105cfu/g), Penicillium spp (1.92 × 104cfu/g): (2.74× 105cfu/g) and Rhizopus (1.92× 103cfu/g): (2.71× 105cfu/g)respectively while the bromate levels ranged from0.02 ± 0.05 ppm to 9.33 ± 0.30 ppm were, an indication of not all bakeries following the standard regulation required by NAFDAC for bread production. Conclusion: The presence of food poisoning bacteria in the bread examined could be traced to raw material quality, sanitary status of equipment, handlers hygiene, environment and storage condition while the amount of potassium bromate content found could threaten consumers' life when consumed regularly and hence, the needs for strict monitoring by the food and drug regulatory agencyenBacteriological examinationPotassium bromateBreadIbadanSagamuArticle
