<p>ISO 21528-1:2017 specifies a method, with enrichment, for the detection of <i>Enterobacteriaceae</i>. It is applicable to</p>
<p>- products intended for human consumption and the feeding of animals, and</p>
<p>- environmental samples in the area of primary production, food production and food handling.</p>
<p>This method is applicable</p>
<p>- when the microorganisms sought are expected to need resuscitation by enrichment, and</p>
<p>- when the number sought is expected to be below 100 per millilitre or per gram of test sample.</p>
<p>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).</p>
<p>NOTE Enumeration can be carried out by calculation of the most probable number (MPN) after incubation in liquid medium. See Annex A.</p>
