The global ISO IWA 32:2019 GMO proficiency test initiative is a collaboration between GOTS, OCA
and Textile Exchange with technical support from Wageningen Food Safety Research. The joint
project has reached a significant milestone: fourteen laboratories from China, Germany, India,
the Netherlands, and Portugal have successfully passed the proficiency test. An overview of the
laboratories that can currently conduct GMO testing as per the ISO IWA 32:2019 method has
now been jointly published by GOTS, OCA and Textile Exchange, which constitutes an
important milestone on the journey towards the widespread use of this standardized protocol.
