Amostras de leite materno do banco da Maternidade Evangelina Rosa, localizada em Teresina, PI (Brasil) foram avaliadas quanto a qualidade microbiologica. As amostras de leite cru apresentaram media de 5,7x105 UFC/mL na contagem de aerobios mesofilos e 6,0x102 UFC/mL na contagem de psicrotroficos. Oito amostras (32%) tiveram valores de 105 a >300 x 10 UFC/mL para contagem de Staphylococcus aureus. Na enumeracao de coliformes totais e fecais os valores obtidos foram de Abstract Maternal milk samples of "Maternidade Evangelina Rosa" bank, located in Teresina, PI (Brazil), were evaluated for its microbiological quality. It was observed that raw milk samples displayed average counts of mesophilic aerobic of 5,7x 105 CFU/mL and psicotrophics counts of 6,0x102 CFU/mL. Eight samples (32%) presented Staphylococcus aureus counts that varied from 105 to >300x101 CFU/mL. In total and fecal coliforms enumeration the values obtained varied from 0,3 to 24 NMP/mL. Pasteurized human milk presented mesophilic aerobic average count of 1,1x102 CFU/mL. None of the analyzed samples presented total, fecal coliforms and S. aureus. The pasteurization is of high importance to maintain the hygienicsanitary quality of human milk bank.
