Bacterial and Fungal studies on sheep and goat's milk in Egypt and Sudan

Abstract

Sheep and goat milk samples were collected randomly of apparently normal udders in Egypt and Sudan, at summer and winter seasons. The total milk samples were prepared for microbiological and aflatoxin examination. The microbiological analysis of the examined sheep and goat milk samples revealed that Aerobic Plate Count mean values for Egyptian goat milk were higher than Sudanese one. The obtained results showed that Staphylococcus aureus and Enterococcus faecalis could be isolated from the examined sheep and goat milk of Egypt and Sudan in summer season and in winter season. Salmonella organisms could be detected in one sample of Egyptian summer sheep milk. Seriological typing revealed that the isolated strain was identified as Salmonella typhimurium . The Aspergillus .flavus and Aspergillus parasiticus strains isolated from sheep and goat milk samples were screened for their ability for aflatoxin production. Aflatoxin B was detected in minimum of l 0 ug 1100 ml and maximum 40 ug/ 100 mi. Aflatoxin M1 and aflatoxin M2 failed to be detected in all the examined milk samples from Egyptian and Sudanese ewe and goat. Therefore, improving the quality of produced milk and to safeguard the consumers against infections, the control measures were discussed and taken in consideration.
