Microbiology of the food chain - Horizontal method for the detection and enumeration of Enterobacteriaceae - Part 2: Colony-count technique (ISO 21528-2:2017)
This part of EN ISO 21528 specifies a method, without pre-enrichment, for the enumeration of Enterobacteriaceae. It is applicable to - products intended for human consumption and the feeding of animals, and - environmental samples in the area of food production and food handling. Enumeration is carried out by counting colonies in a solid medium after incubation at 37 °C (or 30 °C).
This technique is recommended when the number of colonies sought is expected to be more than 100 per millilitre or per gram of the test sample.

Microbiologie de la chaîne alimentaire - Méthode horizontale pour la recherche et le dénombrement des Enterobacteriaceae - Partie 2: Technique par comptage des colonies (ISO 21528-2:2017)
L'ISO 21528-2:2017 spécifie une méthode pour le dénombrement des Enterobacteriaceae. Elle est applicable:
- aux produits destinés à l'alimentation humaine et animale, et
- aux échantillons d'environnement pour la production au stade primaire, la production des aliments et la distribution des aliments.
Cette technique est destinée à être utilisée lorsque le nombre de colonies recherchées est supposé être supérieur à 100 par millilitre ou par gramme d'échantillon pour essai.
La technique du nombre le plus probable (NPP), incluse dans l'ISO 21528‑1, est généralement utilisée lorsque le nombre recherché est censé être inférieur à 100 par millilitre ou par gramme d'échantillon pour essai.
Mikrobiologija v prehranski verigi - Horizontalna metoda za ugotavljanje prisotnosti in števila enterobakterij - 2. del: Metoda štetja kolonij (ISO 21528-2:2017)
Ta del standarda EN ISO 21528 določa metodo za ugotavljanje števila enterobakterij brez predhodne obogatitve. Uporablja se za: – izdelke, namenjene za prehrano ljudi in krmo živali; in – okoljske vzorce na območju proizvodnje hrane in ravnanja s hrano. Ugotavljanje števila se izvaja s štetjem kolonij na trdem mediju po inkubaciji pri 37 °C (ali 30 °C). Ta tehnika se priporoča, kadar se pričakuje več kot 100 kolonij na mililiter ali gram preskusnega vzorca.
