scope:
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.
