Microbiology of the food chain - Method validation - Part 3: Protocol for the verification of reference methods and validated alternative methods in a single laboratory (ISO 16140-3:2021)

This document specifies the protocol for the verification of reference methods and validated alternative methods for implementation in the user laboratory.
This document is applicable to the verification of methods used for the analysis (detection and/or quantification), confirmation and typing of microorganisms in:
—     products intended for human consumption;
—     products intended for animal feeding;
—     environmental samples in the area of food and feed production, handling;
—     samples from the primary production stage.
This document is, in particular, applicable to bacteria and fungi. Some clauses can be applicable to other (micro)organisms or their metabolites, to be determined on a case-by-case basis.
The technical protocols for the verification of validated qualitative methods and validated quantitative methods are described in Clauses 5 and 6. The technical protocol for the verification of validated alternative confirmation and typing methods is described in Clause 7. The protocols for the verification of non-validated reference methods are described in Annex F.

Mikrobiologie der Lebensmittelkette - Verfahrensvalidierung - Teil 3: Arbeitsvorschrift für die Verifizierung von Referenz- und validierten alternativen Verfahren in einem Einzel-Labor (ISO 16140-3:2021)

Dieses Dokument legt die Arbeitsvorschrift fest, die bei der Verifizierung von Referenzverfahren und von validierten alternativen Verfahren zur Umsetzung im Anwenderlabor eingesetzt werden.
Dieses Dokument ist anwendbar auf die Verifizierung von Verfahren zur Untersuchung (Nachweis bzw. quantitative Bestimmung), Bestätigung und Typisierung von Mikroorganismen in:
- Erzeugnissen, die für den menschlichen Verzehr vorgesehen sind;
- Erzeugnissen, die als Futtermittel vorgesehen sind;
- Umgebungsproben im Bereich der Herstellung und Handhabung von Lebensmitteln und Futtermitteln;
- Proben aus dem Bereich der Primärproduktion.
Dieses Dokument gilt insbesondere für Bakterien und Pilze. Einige Abschnitte können auf andere (Mikro )Organismen oder deren Metaboliten angewendet werden. Die Bestimmung muss im Einzelfall erfolgen.
Die technischen Arbeitsvorschriften für die Verifizierung validierter qualitativer Verfahren und validierter quantitativer Verfahren sind in Abschnitt 5 und Abschnitt 6 beschrieben. Die technische Arbeitsvorschrift für die Verifizierung von validierten alternativen Bestätigungs- und Typisierungsverfahren ist in Abschnitt 7 beschrieben. Die Arbeitsvorschriften für die Verifizierung von nicht validierten Referenzverfahren werden in Anhang F beschrieben.

Microbiologie de la chaîne alimentaire - Validation des méthodes - Partie 3: Protocole pour la vérification dans un seul laboratoire de méthodes de référence et de méthodes alternatives validées (ISO 16140-3:2021)

Le présent document spécifie le protocole pour la vérification de méthodes de référence et de méthodes alternatives validées destinées à être mises en œuvre dans le laboratoire utilisateur.
Le présent document est applicable à la vérification de méthodes utilisées pour l'analyse (recherche et/ou quantification), la confirmation et le typage de micro-organismes présents dans:
—          les produits destinés à la consommation humaine;
—          les produits destinés à l'alimentation animale;
—          les échantillons environnementaux dans le domaine de la production et de la manutention de produits alimentaires;
—          les échantillons au stade de la production primaire.
Le présent document est notamment applicable aux bactéries et aux moisissures. Certains articles peuvent être applicables à d'autres (micro-)organismes ou à leurs métabolites, qui doivent être déterminés au cas par cas.
Les protocoles techniques pour la vérification de méthodes qualitatives validées et de méthodes quantitatives validées sont décrits aux Articles 5 et 6. Le protocole technique pour la vérification de méthodes alternatives validées de confirmation et de typage est décrit à l'Article 7. Les protocoles pour la vérification de méthodes de référence non validées sont décrits à l'Annexe F.
