UNE EN ISO 21528-2:2018
This part of ISO 21528 specifies a method for the enumeration of Enterobacteriaceae. It is applicable to ¾ð products intended for human consumption and the feeding of animals; and ¾ð environmental samples in the area of food production and food handling. This technique is recommended when the number of colonies sought is expected to be more than 10 per millilitre or per gram of the test sample. The most probable number (MPN) technique, as included in part 1 of ISO 21528, is generally used when the number sought is expected to be in the range 1 to 100 per millilitre or per gram of test sample.
