Microbiology of the food chain - Estimation of measurement uncertainty for quantitative determinations (ISO 19036:2019)
This document specifies requirements and gives guidance for the estimation and expression of measurement uncertainty (MU) associated with quantitative results in microbiology of the food chain.
It is applicable to the quantitative analysis of:
— products intended for human consumption or the feeding of animals;
— environmental samples in the area of food production and food handling;
— samples at the stage of primary production.
The quantitative analysis is typically carried out by enumeration of microorganisms using a colony-count technique. This document is also generally applicable to other quantitative analyses, including:
— most probable number (MPN) techniques;
— instrumental methods, such as impediometry, adenosine triphosphate (ATP) and flow cytometry;
— molecular methods, such as methods based on quantitative polymerase chain reaction (qPCR).
The uncertainty estimated by this document does not include systematic effects (bias).
Mikrobiologie der Lebensmittelkette - Feststellung von Messunsicherheiten bei quantitativen Bestimmungen (ISO 19036:2019)
Dieses Dokument legt Anforderungen fest und bietet eine Anleitung für die Abschätzung und Angabe der Messunsicherheit (MU), die mit quantitativen Ergebnissen in der Mikrobiologie der Lebensmittelkette verbunden ist.
Sie ist anwendbar für die quantitative Analyse von:
- Produkten, die für den menschlichen Verzehr oder als Futtermittel bestimmt sind;
- Umgebungsproben aus den Bereichen der Herstellung von Lebensmitteln und beim Umgang mit Lebensmitteln;
- Proben aus der Primärproduktion.
Die quantitative Analyse erfolgt in der Regel durch die Auszählung der Mikroorganismen anhand eines Koloniezählverfahrens. Dieses Dokument gilt allgemein auch für andere quantitative Analysen, einschließlich:
- Verfahren der wahrscheinlichsten Keimzahl (MPN);
- instrumentelle Verfahren, wie Impediometrie, Adenosintriphosphat (ATP) und Durchflusszytometrie;
- molekulare Verfahren, wie Verfahren, die auf der quantitativen Polymerase Kettenreaktion (en: quantitative polymerase chain reaction, qPCR) basieren.
Die Schätzung der Unsicherheit, die in diesem Dokument enthalten ist, schließt systematische Effekte (systematische Abweichung von Messungen) nicht ein.
Microbiologie de la chaîne alimentaire - Estimation de l'incertitude de mesure pour les déterminations quantitatives (ISO 19036:2019)
Le présent document spécifie des exigences et fournit des recommandations pour l'estimation et l'expression de l'incertitude de mesure (IM) associée à des résultats quantitatifs en microbiologie de la chaîne alimentaire.
Elle s'applique à l'analyse quantitative des:
— produits destinés à la consommation humaine ou à l'alimentation animale;
— échantillons environnementaux dans le domaine de la production et de la manutention de produits alimentaires;
— échantillons au stade de la production primaire.
L'analyse quantitative est généralement effectuée par le dénombrement de micro-organismes à l'aide d'une technique par comptage des colonies. Le présent document s'applique aussi en général à d'autres analyses quantitatives, telles que:
— les techniques du nombre le plus probable (NPP);
— les méthodes instrumentales, comme l'impédancemétrie, l'adénosine triphosphate (ATP) et la cytométrie en flux;
— les méthodes moléculaires, comme les méthodes fondées sur la réaction de polymérisation en chaîne quantitative (qPCR).
L'incertitude estimée par le présent document n'inclut pas les effets systématiques (biais).
Mikrobiologija v prehranski verigi - Ocena merilne negotovosti pri kvantitativnem določanju (ISO 19036:2019)
Ta mednarodni standard podaja zahteve in napotke za oceno in izražanje merilne negotovosti (MU), povezane s kvantitativnimi rezultati mikrobiologije prehranske verige. Uporablja se za kvantitativno analizo:
– izdelkov, namenjenih za prehrano ljudi ali krmo živali;
– okoljskih vzorcev na področju proizvodnje hrane in ravnanja s hrano; ter
– vzorcev v fazi primarne proizvodnje.
Kvantitativna analiza se običajno opravi s štetjem mikroorganizmov s tehniko štetja kolonij. Na splošno se uporablja tudi za druge kvantitativne analize, vključno s tehnikami najverjetnejšega števila (MPN) in instrumentalnimi metodami. Negotovost, ki jo ocenjuje ta mednarodni standard, ne vključuje sistematičnih učinkov (»resničnost« ali »pristranskost«).
