| Abstract | ||||
| 75 samples of raw milk, small scale ice cream and large scale ice cream (25 each) were collected from different supermarkets and street vendors in Alexandria city, Egypt and examined bacteriologically for the presence of some food poisoning organisms. Psychrotrophic, Coliform, Staphylococcus and Enterococci were 89 present with a mean value of (9.4x108, 7.5x105and 3x102), (1.0x104, 5.6x102 and 0.0), (16.38x103, 8.9 x 10 3 and 0.0) and (6.9x102, 1.6x102 and 7.3x10) in the examined raw milk, small scale and large scale ice cream samples, respectively. E. coli, Klebsiella spp., Enterobacter spp., Pseudomonas spp., Yersinia spp., Aeromonas hydrophila improving the quality of the product were discussed. Staphylococcus aureus and Enterococci could be isolated at varying percentages from the examined samples. The Enteropathogenic E. coli could be isolated from 96% and 20% from raw milk and small scale ice cream samples and identified serologically as : K66, O112: K66, O111: K58, O114 : K90, O78 : K80, O124 : K72, O128 : K67 and O26 : K60. The public health significance O119 and economic importance of existing food poisoning organisms as well as suggestive measure for improving the quality of the product were discussed. | ||||
