ISO (International Organization for Standardization)

International Organization for Standardization (ISO) 21569:2005 describes the procedure to qualitatively detect genetically modified organisms and derived products by analyzing the nucleic acids extracted from the sample under study. ISO/TS 21569-5:2016 specifies a procedure for the detection of a DNA sequence used in genetically modified plants by means of a real-time polymerase chain reaction. The method detects a 78 base pairs long segment of the figwort mosaic virus 34S promoter DNA sequence. ISO 21570:2005 has been established for food matrices, but is also applicable to other matrices, for example, feed and plant samples from the environment. ISO 24333:2009 specifies requirements for the dynamic or static sampling, by manual or mechanical means, of cereals and cereal products, for assessment of their quality and condition. It is applicable to sampling for the determination of heterogeneously distributed contaminants, undesirable substances, and parameters usually homogeneously distributed like those used to assess quality or compliance with specification.
