scope:
This part of ISO 11866-IDF 170 specifies a method for the enumeration of presumptive Escherichia coli by means of a colony-count technique at 44 °C. The method is applicable to - milk, liquid milk products, - dried milk, dried sweet whey, dried buttermilk, lactose, ¯ acid casein, lactic casein and rennet casein, - caseinate and dried acid whey, - cheese and processed cheese, - butter, - frozen milk products (including edible ices), and - custard, desserts and cream. The method specified in this part of ISO 11866-IDF 170 is the preferred method for samples in which comparatively large numbers of presumptive Escherichia coli (more than 100 per gram or 10 per millilitre) are suspected.
