This study was carried out during the period from 5th of August to 25 of November 2003 using 68 samples. The samples were collected from different dairy farms in Khartoum city, half of samples were collected directly from the udder under hygienic conditions and the other half from the last container which goes to market. This research aimed to study the two types of samples as far as number and types of bacteria present to identify the bacterial contamination occurs in the chain of production. The average of total count of bacteria was 1.388 × 108 in first samples (from udder) while the average of the second type of sample was 6.25 ×108 In the second type of sample dominating the types of bacteria isolated were Clostridia, Actinomyces , Staphylococcus, Streptococcus Enterococci, and Pasteurella.
