Abstract: This study was assumed to evaluate the hygienic quality of some fermented milk products. One hundred and thirty random samples (30 each of large scale plain yoghurt, Butter milk, Labneh and 40 samples of skimmed milk Raieb) were collected from dairy shops and supermarkets in Cairo, Giza and El Monofiagovernorates. The collected samples were examined to evaluate their microbial status. The results revealed that Coliforms, total Staphylococci, S. aureus, aerobic spore formers, yeast and mold could be present in high numbers, while Yersinia enterocolitica couldn't be detected in all of the examined samples.
