What is ISO 22753 about?
ISO 22753 discusses molecular biomarker analysis. ISO 22753 describes general requirements, procedures, and performance criteria for evaluating the content of genetically modified (GM) seeds/grains in a lot by a group testing strategy that includes qualitative analysis of sub-sampled groups followed by statistical evaluation of the results.
ISO 22753 is applicable to group testing strategy estimating the GM content on a percentage seed/grain basis for purity estimation, testing towards a given reject/accept criterion and for cases where seed/grain lots are carrying stacked events.
Note: ISO 22753 is not applicable to processed products. Description of the use of group testing strategy are available in References [1], [7], [8], [18], [19] and [20].
Who is ISO 22753 for?
ISO 22753 on molecular biomarker analysis is useful for:
- Food scientists
- Biotechnology laboratories
- Food technologists
- Food and food products inspection authorities
Why should you use ISO 22753?
Seed and grain testing are used throughout the world to commercially define the purity of seed and grain lots. Commercial requirements for labelling agricultural products with genetically modified organism (GMO) content at a specified threshold level both as a seed/grain contaminant and a food ingredient have become common to satisfy regulations and consumer demands. Conformance with these specifications is evaluated at various points of the supply chain, often starting with the harvested grain.
The group testing strategy described in ISO 22753 provides a reliable alternative to estimate the GM content since whole seeds/grains are the sample material. The process described in ISO 22753 provides a method to accurately estimate the percentages of GM seeds/grains in a lot irrespective of the presence of stacked event seeds/grains.
