This part of ISO 13366 I IDF 148 specifies a method for the counting of somatic cells in both raw and chemically preserved milk. The description is applicable for the counting of somatic cells in cow milk, provided that the eventually mentioned prerequisites are met. This method is suitable for preparing standard test samples and determining reference method values that are required for calibrating mechanized and automatic cell-counting methods.

This part of ISO 133661 IDF 148 gives guidance on the operating conditions for counting somatic cells, in both raw and chemically preserved milk, using fluoro-opto-electronic somatic cell counters in which either a rotating disc technique or flow cytometry is applied in the counting section. The guidance is applicable to the counting of somatic cells in raw cow milk. The guidance is also applicable to raw milk of other species, such as goat, sheep and buffalo, if the specified prerequisites are met.

This International Standard specifies a method for the enumeration of presumptive Lactobacillus acidophilus in milk products on a selective medium by using a colony-count technique at 37 °C. The method is applicable to fermented and non-fermented milks, milk powders and infant formulae where presumptive L. acidophilus is present and in combination with other lactic acid bacteria and bifidobacteria. The method is not applicable when the number of presumptive L. acidophilus is less than 104 CFU/g and the numbers of Lactobacillus rhamnosus, Lactobacillus reuteri and Lactobacillus paracasei subsp. paracasei are greater than 106 CFU/g.

This part of ISO 14461.IDF 169 describes a procedure for testing the performance of the colony-count technique within a laboratory by establishing the within-laboratory variability of its technique and identifying those steps that are associated with excessive variability.The procedure is also suitable for checking the proper observance of Good Laboratory Practice (GLP), which may be a prerequisite for participation in interlaboratory tests of colony-count methods.EXAMPLE Appropriate test samples are raw milk, pasteurized milk and dried milk.
