The invention relates to a method for the treatment of milk for the production of cheese milk having a reduced content of germs and bacteria, and to an installation for carrying out said method. The aim of the invention is to devise a corresponding method and installation with which the advantages resulting from the treatment of the milk at a low or at a high temperature level can be variably combined depending on the focus. This aim is achieved by a second method variant according to which the supplied milk (M) is subdivided into a first milk portion (MI) and a second milk portion (M2), the first milk portion (M1) is subjected to centrifuging (ZF), the second milk portion (M2) is subjected to the bacteria controlling treatment (BSB) together with • either the at least first retentate (R-1) obtained in the at least first microfiltration (MF-I) • or the at least first retentate (R-1) and in addition with the milkfat fraction (RF) or a first portion of the milkfat fraction (RF1). BSB is a thermal treatment by heating the milk to above 100°C and the mixture treated this way and consisting of • either second components (K2), which consist of a non-centrifuged treated second milk portion (M2*) and a treated at least first retentate (R-1*), • or third components (K3), which consist of the second components (K2) and a treated milkfat fraction (RF) or a treated first milkfat fraction (RF1*), is combined and mixed with the at least first permeate (P-1) or the last permeate resulting from the last microfiltration in order to obtain standardized cheese milk (SKM).
