摘要：AbstractA total of 150 samples of raw milk, 75 each of farm and market milk were collected from different farms and supermarkets in Beni-Suef Governorate, in addition to 30 stool samples from milk handlers and 25 milker's hand swabs were examined for the presence ofEscherichia coli,E. coliO157:H7,Salmonella,AeromonasandYersinia. Isolates were identified biochemically and serologically. The obtained results revealed thatE. coliwas detected in a percentage of 26.7% and 16% in the examined raw market and bulk farm milk respectively, while in stool and hand swabs samples were 16.6% and 16%, respectively.E. coliO157:H7 andSalmonellaspp. failed to be detected in any of the examined samples. Additionally, 45% and 16.7% of the recoveredE. colistrains from the examined raw market and farm milk samples were enteropathogenic O166, while 55% and 83.3 were untypable, respectively. On the other hand 60% of human stool samples isolates were O 148 and 40% of the isolates were untypable, while 100% of the hand swab isolates were untypable. The results also exhibits isolation rate ofAeromonas hydrophilain a percentage of 24%, 13.3%, 10% and 16% from market milk, farm milk samples, stool and hand swabs respectively. WhileYersinea enterocoliticarepresent 3.3% in the stool samples only. The public health significance of isolated strains as well as suggested control measures were discussed.
