Abstract
This study investigated the microbial quality
of cassava bread produced in selected communities of Bauchi Local
Government Area, Bauchi State. The research aimed to identify and characterize
the bacterial contaminants associated with cassava bread, considering
its growing importance as a substitute for wheat bread in Nigeria. Laboratory
analyses were carried out using cultural, morphological, and biochemical
methods to determine the types and frequency of microbial isolates. The results
revealed the presence of three bacterial species: Staphylococcus aureus,
Escherichia coli, and Salmonella spp. Morphological and biochemical tests
confirmed their identities, with S. aureus showing positive catalase and
coagulase activity, E. coli being catalase and indole positive, and Salmonella
spp. displaying distinct Gram-negative rod characteristics. Frequency analysis
indicated that S. aureus was the most prevalent isolate (45.43%), followed by
E. coli (36.86%), while Salmonella spp. was the least frequent (18.18%). The
findings demonstrated that cassava bread sold in the study area is
susceptible to microbial contamination due to poor hygiene during production,
handling, and storage. The predominance of S. aureus suggests contamination
from food handlers, while the presence of E. coli points to possible fecal
contamination from water or the environment. Although less frequent, the
detection of Salmonella spp. underscores the risk of foodborne illnesses
associated with cassava bread consumption. It is concluded that cassava
bread, despite its nutritional and economic benefits, poses potential public
health risks if produced under unhygienic conditions. The study recommends
strict adherence to hygiene by food handlers, regular monitoring by health
authorities, use of treated water in production, and public awareness on food
safety.
