ISO IWA 32 Test for Screening of Genetically Modified Organisms in Cotton and Textile Products

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO IWA 32 testing. This standard provides requirements and recommendations for laboratories performing genetically modified organism (GMO) analysis in cottonseed, leaves, cotton fiber and cotton fiber-derived materials.

The following are covered by this document:

• Identifying materials to be evaluated in the next steps of the cotton fabric manufacturing process based on the probability of obtaining good quality, fit-for-purpose DNA from the materials;
• Specifying a method for efficient DNA isolation from cotton and cotton-derived materials described in point A;
• Specify the cotton-specific method(s) to be used as a control for reproducible DNA;
• Determining the screening procedure that provides the optimal chance to detect GMOs as a result of the performance of the screening test for the lowest number of genetically modified (GM) elements.

The protocol allows screening of all currently known GM cotton events and is set up to optimize the probability of detection of unknown GM cotton events possibly containing similar DNA sequences. More information is given in CEN/TS 16707.

Sampling is beyond the scope of this document.

A recommended sampling method is given in ISO 6497. General guidance for sampling bulk materials or cotton-based products is available in standards such as ASTM D1441‑12 and CEN/TS 15568.
