Abstract
Cheese is an excellent source of protein, fat and minerals such as calcium, iron, phosphorus, vitamins and essential amino acids and therefore it is an important food in the diet of youngsters and elderly. Damietta cheese is the most popular soft white pickled cheese in Egypt and in other Middle Eastern countries.
Dairy products are liable to contamination with different types of microorganisms from different sources during production, processing and handling, which lead them to be unfit for consumption and constitute a public health hazard. So, twenty-five of small scale manufactured Damietta cheese samples were collected from different dairy shops and markets in Sharkia, Egypt, were examined for their hygienic and microbiological quality.
The mean value of total bacterial count in examined locally manufactured Damietta cheese samples was 2.88×1010± 0.20×109CFU/ gm.
The recorded results showed that the mean coliform count in examined Damietta cheese was 3.31×109±0.20×109CFU/ gm.
The mean staphylococci count in examined Damietta cheese was 2.09×107±0.20×106CFU/ gm.
S. aureus could be isolated from examined Damietta cheese samples in percentage of 70.83% of isolated staphylococcal strains.
Yersinia spp. could be isolated with a percentage of12% out of examined Damietta cheese samples.
Yersinia enterocolitica could be detected in percentage of 66.67% from Damietta cheese samples.
