Abstract | |||||||||||||||||
| The microorganisms involved in dry-yam (gbodo) and water used in parboiling from different source (well, pipe-borne, river, stream and pond) were investigated. There was predominance of Staphylococcus aureus , fungi and coliforms in the gbodo samples. Coliforms were also observed in all the parboiling water. In gbodo, the total viable bacterial count was generally high, ranging from 1.1 x 106 cfu/ml from Oyo processing area to 7.8 x 105 cfu/ml from Iseyin processing areas. A large percentage of the microorganisms involved in gbodo were fungi ranging from 8.5 x 105 cfu/ml in samples collected from Abeokuta to 1.2 x 106 cfu/ml in samples from Ibarapa. S. aureus was isolated from all the dry yam samples with counts ranging from 2.5 x 103 cfu/ml in samples collected from Iseyin processing area to 9.0 x 104 cfu/ml from Baruba processing area. The control sample prepared at the laboratory has a low microorganism' population compared with all the collected samples. | |||||||||||||||||
