Microbiology of the food chain - Horizontal method for determination of hepatitis A virus and norovirus using real-time RT-PCR - Part 2: Method for detection (ISO 15216-2:2019)

This document specifies a method for detection of hepatitis A virus (HAV) and norovirus genogroups I (GI) and II (GII), from test samples of foodstuffs [(soft fruit, leaf, stem and bulb vegetables, bottled water, bivalve molluscan shellfish (BMS)] or surfaces using real-time RT-PCR.
This method is not validated for detection of the target viruses in other foodstuffs (including multi-component foodstuffs), or any other matrices, nor for the detection of other viruses in foodstuffs, surfaces or other matrices.

Mikrobiologie der Lebensmittelkette - Horizontales Verfahren zur Bestimmung von Hepatitis-A-Virus und Norovirus in Lebensmitteln mittels Real-time-RT-PCR - Teil 2: Nachweisverfahren (ISO 15216-2:2019)

Dieses Dokument legt ein Verfahren für den Nachweis von Hepatitis-A-Viren (HAV) und Noroviren der Genogruppen I (GI) und II (GII) in Untersuchungsproben von Lebensmitteln [weiches Obst, Blatt-, Stängel- und Zwiebelgemüse, in Flaschen abgefülltes Trinkwasser, zweischalige Weichtiere (BMS, en: bivalve molluscan shellfish)] oder auf Oberflächen mittels Real-time-RT-PCR fest.
Dieses Verfahren ist weder für den Nachweis der Zielviren in anderen Lebensmitteln (einschließlich zusammengesetzter Lebensmittel) oder anderen Matrices noch für den Nachweis anderer Viren in Lebensmitteln, auf Oberflächen oder anderen Matrices validiert.

Microbiologie dans la chaine alimentaire - Méthode horizontale pour la recherche des virus de l'hépatite A et norovirus par la technique RT-PCR en temps réel - Partie 2: Méthode de détection (ISO 15216-2:2019)

Le présent document spécifie une méthode de détection du virus de l'hépatite A (VHA) et des norovirus des génogroupes I (GI) et II (GII) dans des échantillons pour essai d'aliments (baies, légumes feuilles, tiges et bulbes, eau embouteillée, mollusques bivalves) ou sur des surfaces par RT-PCR en temps réel.
Cette méthode n'est pas validée pour la détection des virus cibles dans d'autres aliments (y compris les aliments à plusieurs composants) ou d'autres matrices, ni pour la détection d'autres virus dans les aliments, sur les surfaces ou dans d'autres matrices.

Mikrobiologija v prehranski verigi - Horizontalna metoda za ugotavljanje virusa hepatitisa A in norovirusov z RT-PCR v realnem času - 2. del: Metoda za ugotavljanje (ISO 15216-2:2019)

Standard EN-ISO 15216-2 določa metodo za ugotavljanje virusa hepatitisa A (HAV) in norovirusov I (GI) in II (GII) iz preskusnih vzorcev živil (mehko sadje, listna, stebelna in gomoljna zelenjava, ustekleničena voda, mehkužci-školjke (BMS)) ali površin z uporabo RT-PCR v realnem času. Ta metoda ni potrjena za odkrivanje ciljnih virusov v drugih živilih (vključno s sestavljenimi živili) ali kateri koli drugih zmeseh, niti za odkrivanje drugih virusov v živilih, površinah ali drugih zmeseh.
