Abstract
The microbiological quality of two batches of fura de nunu sample was studied. The samples were obtained from six different hawkers at one-week interval in Mami Market, Obirinze, Owerri Metropolis. The same fura de nunu hawker sampled in week 1 and week 2. All the samples collected were analyzed microbiologically. The data obtained were subjected to One-way ANOVA to test for significant difference. The viable count showed variation in the colony count in Week 1 and week 2 from the same hawker. The coliform count showed variation from the same hawker. The gram reaction of bacteria obtained from different hawkers shows that gram positive and gram-negative were more predominant. The result ranged from 3.8×107 cfu/ml to 7.1×107 cfu/ml. The microbial limit for the total viable colony count is 1.0×102 cfu/ml. E. coli was confirmed to be present in almost all the samples except sample A, B and F. The presence of E. coli indicates the possibility of other pathogenic microorganisms present in the samples. The presence of coliform in Fura de nunu samples indicates probable fecal contamination and the presence of E. coli bacteria in all most all the samples are the major biotype of the family. It is recommended that a standard processing method that will ensure Faru de nunu of the highest microbial and nutritional quality be developed and the technology transferred to the local producers.
