This study aimed to identify key factors that contribute to the disposal of the milk donated to the Human Milk Bank of the city of Varginha, MG, and link the causes of such discharge to characteristics of the donator mothers. The research was carried out in the first semester of 2008 with 45 volunteer breast milk donators. The breast milk samples were collected and analyzed at the Human Milk Bank of Varginha-MG. The personal and social-economic data on the donators were obtained from their registration files. Samples obtained from both manual and mechanical milking types were used. All the procedures used for analysis of the breast milk quality were carried through according to the standard techniques of the Breast Milk Bank. For statistical analysis, techniques of Descriptive Statistics were used, estimation and tests of proportions c2 (chi-square) independence at 5% significance using the software R. As a result, most of the donators (64,44%) ranged from 19 to 30 years of age, 46,67% white, 62,22% having a salary income from 1,5 to 3 minimum wages per month, 60% were primipary and 51,11% had been encouraged by the BLH to donate milk. The average amount of milk donated was from a 100 to 150 mL/donator. Of the total amount of breast milk collected 76,67 liters (72,57%) were used and 29 liters (27,43%) were discarded, 19,2 liters of which discarded on the re-store procedure. Of the samples analyzed, 19 (5,28%) showed dirt and were discarded. The average acidity shown was 3,98º Dornic and 9 (2,64%) samples showed acidity higher than 8º Dornic and were discarded. 31,93% of the analyzed samples showed 800 Kcal/L of human breast milk and the calories average amount was 591,08 Kcal/L. During the microbiologic analysis only 12 (3,61%) samples showed a positive result as for total cholyform and were discarded. It is suggested that the presence of dirt in milk from donors depends on the type of milking, the donor´s age and number of children. In the presence of acid > 8ºD, it is suggested to result from the age of the donor, her social and economic level, the number of children she had previously had and age of the milk. In the presence of positivity for the microbiological test, it is suggested to result from the social and economic level and marital status of the donor. It was found that ethnicity did not affect the variables that favored the disposal of the milk donated to the BLH of the city of Varginha-MG. Looking forward to breast milk quality, it should never be considered as a casual phenomenon, but a process performed in an intelligent way so to avoid any inter-occurrences which might promote the disqualification of the product.
