Anotace textu normy ČSN EN ISO 21528-1   (560096)

This document 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 this document 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.
