ISO 21528:2017 Microbiology of the food chain – Horizontal method for the detection and enumeration of Enterobacteriaceae – Part 1: Detection of Enterobacteriaceae
CDN $192.00
Description
ISO 21528-1:2017 specifies a method, with enrichment, for the detection of Enterobacteriaceae. It is applicable to
– products intended for human consumption and the feeding of animals, and
– environmental samples in the area of primary production, food production and food handling.
This method is applicable
– when the microorganisms sought are expected to need resuscitation by enrichment, and
– when the number sought is expected to be below 100 per millilitre or per gram of test sample.
A limitation on the applicability of ISO 21528-1:2017 is imposed by the susceptibility of the method to a large degree of variability (see Clause 11).
NOTE Enumeration can be carried out by calculation of the most probable number (MPN) after incubation in liquid medium. See Annex A.
