Determination of GM Maize Event 59122 in Multigrain Bread Mix and GM Soybean Event CV127 in Soybean Powder
Report of the EURL GMFF Proficiency Test GMFF-22/02
The European Union Reference Laboratory for Genetically Modified Food and Feed (EURL GMFF) organised the proficiency test (PT) “GMFF-22/02” for the determination of GMOs in food and feed products to support the implementation of Regulation (EU) 2017/625 [1]. Test item T1 consisted of a dry all-in mix for preparing multigrain bread spiked with flour of maize event 59122 (Unique Identifier DAS-59122-7). Test item T2 was composed of ground soybean seeds spiked with ground seeds of GM soybean event CV127 (Unique Identifier
BPS-CV127-9). The EURL GMFF evaluated the homogeneity and stability of the test items and derived the assigned values from independent measurement datasets obtained in the EURL GMFF laboratories. The assigned values (with expanded measurement uncertainty [k=2]) were 1.75 ± 0.25 m/m % for 59122 and 1.18 ± 0.17 m/m % for CV127.
Sixty-three laboratories participated to the PT round, consisting of 48 NRLs from 24 EU Member States, 11 EU OCLs and 4 OCLs from EU-neighbouring countries.
The vast majority (over 90 %) of the other laboratories proved their satisfactory performance (expressed as z score) for the analysis of 59122 maize in multigrain bread mix and CV127 soybean in soybean flour.
The evaluation of this PT round confirms that most NRLs and OCLs are able to monitor and quantify mass fractions of GMOs in food and feed samples in the frame of Regulation (EU) 2017/625.
