Mikrobiologjia e ushqimeve dhe materialeve për ushqimin e kafshëve - Reaksioni zinxhir polymerase (PCR) për zbulimin e patogjenëve që lindin në ushqime - Kërkesat për përgatitjen e mostrave për zbulimin cilësor

Microbiology of food and animal feeding stuffs - Polymerase chain reaction (PCR) for the detection of food-borne pathogens - Requirements for sample preparation for qualitative detection (ISO 20837:2006)

Scope

ISO 20837:2006 provides criteria and examples for sample preparation in order to obtain PCR-compatible samples or nucleic acids of suitable quality and quantity for PCR.
It provides a description of the general principles involved. References to standards concerning the enrichment of microorganisms are given in Annex A, and a detailed method for DNA extraction is given in Annex B.
ISO 20837:2006 has been established for food matrices, but could also be applied to feed and agricultural/environmental matrices with some adaptations, if necessary.
