Abstract: One hundred random samples of market and bulk raw milk (50 of each) and 50 concentrated (25 each of condensed and evaporated) milk, collected from different localities in Damietta Governorate. A survey was conducted to determine the hygienic quality of concentrated and raw milk samples. The obtained results revealed that the mean values of acidity in examined market and bulk raw milk were 0.20±0.0007 and 0.21±0.0007 respectively. The methylene blue reduction time showed that 64% of examined raw milk samples had a reduction time 5 hours or more while 36% had a reduction time less than 5 hours. The mean total colony counts/ml of examined market and bulk raw milks were 3.7×107 and 2.7×107 respectively. Prevalence of coliforms contamination were 84% and 74%, while the mean coliform counts (MPN/ml) were 5 X 102±0.85 and 77.8±0.30 for market and bulk raw milk samples respectively. Prevalence of E. coli in the examined market and bulk raw milk samples were 66% and 86% with mean value of 39.6±0.99 and 6.2±0.63/ml of milk respectively. Out of the tested E. coli isolates (10) E. coli serotypes (O152 poly 8), (O26 poly 1), (O63 poly 5), (O164 poly 8) and (O86a poly 1) represented 3, 3, 2, 1, and 1 of the total isolates respectively.
