Este estudo visou analisar a qualidade microbiológica do leite humano cru recebido em um banco de leite humano (BLH), quantificando os microrganismos aeróbios mesófilos, Staphylococcus coagulase positivos (ECP), coliformes totais e Escherichia coli. Foram realizadas análises microbiológicas em 60 amostras de leite humano cru recebidas no BLH e os resultados foram os seguintes: o microrganismo E. coli foi positivo em 50% das amostras analisadas, os coliformes totais em 75% delas, o ECP em 46,66% e em 96,66% do total das amostras foram detectados microrganismos aeróbios mesófilos. Das amostras analisadas, a população de E. coli foi positiva em 93,33% (28 amostras) com uma variação entre 1 e 99 NMP/mL; 3,33% (1 amostra) entre 104 e 9,9 x 104 NMP/mL; 3,33% (1 amostra) entre 105 e 9,9 x105 NMP/mL. A população de coliformes totais que foi positiva em 57,77% (26 amostras) das amostras analisadas ficou entre 1 e 99 NMP/mL; 24,4% (11 amostras) ficaram entre 102 e 9,9x102 NMP/mL; 2,22% (1 amostra) entre 103 e 9,9x103 NMP/mL; 8,88% (4 amostras) entre 104 e 9,9x104 NMP/mL; 4,44% (2 amostras) entre 105 e 9,9x105 NMP/mL; 2,22% (1 amostra) entre 106 e 9,9x106 NMP/mL. Os microrganismos aeróbios mesófilos apresentaram-se na quase totalidade das amostras, sendo que 17,24% (10 amostras) variaram de 1 a 99 UFC/mL; 17,24% (10 amostras) entre 102 e 9,9x102 UFC/mL; 10,34% (6 amostras) ficaram entre 103 e 9,9 x 103 UFC/mL; 25,86% (15 amostras) entre 104 e 9,9 x104 UFC/mL; 17,24% (10 amostras) entre 105 e 9,9 x 105 UFC/mL; 10,34% (6 amostras) entre 106 e 9,9x106 UFC/mL e 1,72% (1 amostra) entre 107 e 9,9x107 UFC/mL. Porém, 3,33% (2 amostras) apresentaram-se negativas. Do total de amostras analisadas, o grupo dos microrganismos ECP apresentouse em 78,57% (22 amostras) com variação entre 1 e 99 UFC/mL; em 3,57% (1 amostra) entre 102 e 9,9x102 UFC/mL; 10,71% (3 amostras) entre 103 e 9,9x103 UFC/mL e 7,14% (2 amostras) entre 104 e 9,9 x 104 UFC/mL. / This paper aimed to analyze the microbiological quality of the raw human milk which is received in a human milk bank (HMB) by quantifying the aerobic mesophiles, Staphylococcus aureus (SCP), total coliforms and Escherichia coli. Sixty (60) samples of raw human milk received in HMB were microbiologic analyzed and the results were as follows: the E. coli microorganism was positive in 50% of the analyzed samples, the total coliforms were in 75% of them, the ECP in 46,6% and in 96,6% of the total amount of samples aerobic mesophiles microorganisms were detected. From the total analyzed samples, the population of E. coli was positive in 93,33% (28 samples) with a variation between 1 and 99 NMP/mL; 3,33% (1 sample) was between 104 and 9,9x104 NMP/mL; 3,33% (1 sample) was from 105 to 9,9x105 NMP/mL.

The aerobic mesophiles microorganisms were presented in almost all the samples, being: 17,24% (10 samples) with a variation of 1 to 99 UFC/mL; 17,24% (10 samples) between 102 and 9,9x102 UFC/mL; 10,34% (6 samples) were between 103 and 9,9x103 UFC/mL; 25,86% (15 samples) between 104 and 9,9x104 UFC/mL; 17,24% (10 samples) between 105 and 9,9x105 UFC/mL; 10,34% (6 samples) between 106 and 9,9x106 UFC/mL and in 1,72% (1 sample) between 107 and 9,9x107 UFC/mL.
