Abstract

A total of 35 of raw milk samples were collected from street vendors and different supermarkets in Ismailia and Port Said cities and subjected to sensory, chemical and microbiological evaluation. The results showed that acidity % was 0.38+0.02 and Fat% was 2.76±0.07. Microbiologically the mean value of total Staph. aureus was 6.37±0.15 (Log₁₀) cfu/ml,. Salmonellae failed to be detected. While the mean value of total Enterobacteriacaea count was 7.91±0.27 (Log₁₀) cfu/ml. Also, the mean value of totalColiform count was 7.65± 0.35(Log₁₀) c fu/ml, and the mean value oftotal yeasts and mold count was 3.26 ± 0.09 (Log₁₀) cfu/ml. Finally, significance of food spoilage and poisoning isolates, possible sources of contamination and some recommendations to improve the quality of this product were discussed.
