EN ISO 21528-1:2017

Microbiology of the food chain - Horizontal method for the detection and enumeration of Enterobacteriaceae - Part 1: Detection of Enterobacteriaceae (ISO 21528-1:2017)

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.

Microbiologie de la chaîne alimentaire - Méthode horizontale par la recherche et le dénombrement des Enterobacteriaceae - Partie 1: Recherche des Enterobacteriaceae (ISO 21528-1:2017)

L'ISO 21528-1:2017 spécifie une méthode pour la recherche des Enterobacteriaceae avec enrichissement. 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 méthode est applicable:
-      lorsque les micro-organismes recherchés nécessitent une revivification par enrichissement, et
-      lorsque le nombre recherché est supposé être inférieur à 100 par millilitre ou par gramme d'échantillon pour essai.
Des limites sont imposées aux possibilités d'application de l'ISO 21528-1:2017 du fait que ces méthodes sont sujettes à de grandes variations (voir l'Article 11).
NOTE       Le dénombrement peut être effectué en calculant le nombre le plus probable (NPP) après incubation en milieu liquide. Voir l'Annexe A.

Mikrobiologija v prehranski verigi - Horizontalna metoda za ugotavljanje prisotnosti in števila enterobakterij - 1. del: Ugotavljanje prisotnosti enterobakterij (ISO 21528-1:2017)

Ta standard določa metodo najverjetnejšega števila (MPN) s predhodno obogatitvijo za ugotavljanje prisotnosti enterobakterij. Uporablja se za:
– izdelke, namenjene za prehrano ljudi in krmo živali; in
– okoljske vzorce na območju proizvodnje hrane in ravnanja s hrano; in
– vzorce iz primarne proizvodnje.
