AB - Studies were carried out to assess that effect of
processing on the microbial load of maize meal products
sold within Enugu metropolis using appropriate microbial
and biochemical techniques. Eight pathogenic organisms
(Staphylococcus aureus, Escherichia coli, Salmonella
enteritidis, Klebsiella pneumoniae, Streptococcus spp.,
Aspergillus niger, Bacillus cereus and Candida albican)
were isolated in the processed (Akamu, Agidi and Kunu
Zaki) and unprocessed maize samples. The pH levels of
Kunu Zaki, Akamu, Agidi and unprocessed maize
samples were 5.6, 5.1 and 4.9, respectively. The
percentage mean bacterial counts in the samples were
43.32, 34.35, 15.00, 3.70 and 3.53% for Escherichia coli,
Staphylococcus aureus, Klebsiella pneumoniae,
Streptococcus spp. and Salmonella enteritidis,
respectively. The percentage fungal contamination of the
processed and unprocessed samples were 78.49, 14.22
and 7.29% for Bacillus cereus, Aspergillus niger and
Candida albican, respectively. The mean bacterial and
fungal counts in the processed and unprocessed sample
were within tolerable limits of human consumption. The
samples were contaminated with the isolated pathogenic
organisms in the following order: Kunu
Zaki>Akamu>Agidi>unprocessed maize.
