El uso de leche humana de los bancos de leche requiere un proceso térmico para eliminar los riesgos microbiológicos. Se hizo una evaluación sobre la estabilidad de la capacidad bactericida de la leche humana siguiendo dos modalidades de pasterización térmica: (63°C/30 minutos) y (75°C/15 segundos). Se analizaron 10 muestras. En cada muestra se evaluó el efecto de ambos tratamientos térmicos sobre la capacidad bactericida contra E. coli en relación a la capacidad de leche fresca. Todas las muestras que se analizaron tenían capacidad bactericida. La pasterización de la leche humana indujo una perdida significativa de esta capacidad que fue más pronunciada después del proceso de tratamiento con alta temperatura que con baja temperatura. Leche sin tratamiento, leche pasteurizada a baja temperatura y leche pasteurizada a alta temperatura mostraron reducción en el crecimiento de E. coli en el 70.10%, 52.27% y 36.39% respectivamente. En conclusión, la leche humana posee actividad antibacterial que se pierde en parte como resultado del proceso térmico. Esta capacidad bactericida se conserva mejor a bajas temperaturas, pasteurización prolongada.
