Abstract
Fifty random ice-cream and yoghurt samples (25 each from ice cream
and yoghurt) collected from different localities in Sharkia Governorate,
Egypt were examined for detection and enumeration of staphylococci and
their enterotoxins and Salmonella.
The mean value of staphylococci count /ml in examined ice-cream and
yoghurt samples were 1.7 x 106 ± 8 x 105 and 0.38x106 ± 7.4x104
respectively.
S. aureus could be isolated from 32% and 12% of examined ice-cream
and yoghurt samples, while S. epidermidis could be detected in 68% and
88% of them respectively.
Concerning the Incidence of enterotoxin A and enterotoxin B in
examined ice cream samples (S. aureus) were 25% and 12.5%, respectively
while in case of yoghurt samples the incidences were 0 and 33.3%,
respectively.
No enterotoxin C or enterotoxin D could be detected in all examined
samples.
Salmonella failed to be detected in all examined ice-cream and yoghurt
samples.
The public health importance and economic significance of isolated
microorganisms as well as their control measures were discussed to improve
the quality of ice-cream and yoghurt to safe guard the consumers from infection.
