Microbiology of the food chain - Polymerase chain reaction (PCR) for the detection and quantification of microorganisms - General requirements and definitions (ISO 22174:2024)
This document specifies the general requirements for the in vitro amplification of nucleic acid sequences (DNA or RNA).
This document is applicable to the testing for microorganisms and viruses from the food chain using the polymerase chain reaction (PCR). This document, or parts of it, is applicable to other fields of PCR diagnostics based on a case-by-case evaluation.
The minimum requirements laid down in this document are intended to ensure that comparable and reproducible results are obtained in different laboratories.
This document has been established for microorganisms from the food chain and is applicable to:
— products intended for human consumption;
— products for feeding animals;
— environmental samples in the area of food and feed production and handling;
— samples from the primary production stage.
Mikrobiologie der Lebensmittelkette - Polymerase-Kettenreaktion (PCR) zum Nachweis von Mikroorganismen - Allgemeine Anforderungen und Definitionen (ISO 22174:2024)
Dieses Dokument legt die allgemeinen Anforderungen an die in-vitro-Vervielfältigung (Amplifikation) von Nukleinsäuresequenzen (DNA oder RNA) fest.
Dieses Dokument gilt für die Untersuchung auf Mikroorganismen und Viren aus der Lebensmittelkette unter Anwendung der Polymerase-Kettenreaktion (polymerase chain reaction, PCR). Dieses Dokument, oder Teile davon, gilt auf der Grundlage einer Einzelfallbeurteilung auch für andere Bereiche der PCR-Diagnostik.
Die in diesem Dokument festgelegten Mindestanforderungen dienen dazu, vergleichbare und reproduzierbare Ergebnisse in verschiedenen Laboren sicherzustellen.
Dieses Dokument wurde für Mikroorganismen aus der Lebensmittelkette erstellt und ist anwendbar auf
- Produkte, die für den menschlichen Verzehr vorgesehen sind,
- Produkte für das Füttern von Tieren,
- Umgebungsproben im Bereich der Herstellung und Handhabung von Lebensmitteln und Futtermitteln,
- Proben aus dem Bereich der Primärproduktion.
