One hundred and one quarter camel's milk samples from apparently healthy lactating she camels were collected in sterile bottles in order to be evaluated microbiologically and chemically and to distinguish the prevalence of subclinical mastitis in camel and their microbial causes. Among the positive CMT samples, the incidence of CMT (+) score, CMT (++) score and CMT (+++) score were 26.7%, 12.9 % and 9.9%, respectively. The mean SCC of negative and positive CMT milk samples were 69 x10³ ± 7.32 & 304 x10³ ± 2.52, respectively. The study confirmed the high correlation between CMT and SCC in both negative and positive CMT camel's milk samples. The most common causes of subclinical mastitis in examined camel milk samples were CPS, CNS and coliforms. Moreover, it has been reported that raw camel's milk has high levels of total aerobic count, coliform counts, total yeast and mould counts and coagulase positive staphylococci. The analysis of variance (ANOVA) clarified the significant differences of means between normal and mastitic milk at (p < 0.05) in fat %, protein%, urea mg%, total solids %, SNF%, SCC, TBC, staphylococci count, coliform count and yeast counts. In conclusion, fresh camel milk is a perfect and highly nutritional food if produced under acceptable hygienic measures to be free from any human health hazards due to subclinical mastitis or post milking contamination.
