Abstract A hundred fifty randomly collected samples of ice cream, rice pudding and mehallabia (50, each) from different localities in El-Dakhla city, New Valley Governorate, Egypt, were microbiologically examined. The obtained results showed the T. B.C found in all the examined ice cream samples, with an average count CFU/ml. While, the occurrence of psychrotrophic bacteria was 66% with an average count CFU/ml, total coliforms and fecal coliforms existed in all the examined samples with an average count and CFU/ml, respectively. S. aureus, yeast and mold were detected in 18, 96 and 70% with an average count , and CFU/ml, respectively. E. coli was detected in 20%, while anaerobes were not detected in any of the examined samples. In rice pudding samples, the T.B.C, total coliforms and fecal coliforms existed at 100, 94 and 90% in the tested rice pudding samples, with counts ranged between - , - and - CFU/ml, respectively. E. coli, S. aureus, yeasts and mold were found in 16, 10, 94 and 74%, respectively. The S. aureus count ranged from to , yeast and mold counts ranged from to and to CFU/ml, respectively. All the examined samples were negative for psychrotrophic bacteria and anaerobes. While, in mehallabia samples, the average counts were , , , , and CFU/ml, for T.B.C, total coliforms, fecal coliforms, S. aureus counts, yeast and mold, respectively. The positive % of aerobic plate, total coliforms, fecal coliforms, E. coli, S. aureus counts, yeast and mold were 100, 90, 80, 10, 12, 90 and 64, respectively. All the examined samples were negative for psychrotrophic bacteria and anaerobes. |
