Background and Aim : Health of the milk and dairy products are highly important for the consumers. Raw contaminated milk and dairy products are one of the most important means of transmission of brucellosis to consumers. The purpose of this study was to evaluate the intensity of contamination of the raw milk to the Brucella spp. in the raw milk collection centers and distributed area in Mashhad and suberbs. Materials and Methods: Totally 265 raw milk samples were collected in a six month period from these centers and examined by Milk Ring Test (MRT) and other microbiological tests. Results: six samples (2.26%) were positive by MRT. From two of these (0.75%) Brucella abortus were isolated and confirmed by microbiological culture and biochemical tests. No Brucella melitenosis were isolated from the samples. Conclusion: Results of the experiment show the seriousness of the Brucellosis transmission to human consumers with raw milk and dairy products.
