Determination of GM Soybean MON89788 in Meat Paté (T1) and GM Maize T25 in Maize Flour (T2).
EURL GMFF Proficiency Testing Report GMFF-21/02
The European Union Reference Laboratory for Genetically Modified Food and Feed (EURL GMFF) organised a proficiency testing (PT) round (GMFF-21/02) for the determination of GMOs in food and feed materials to support Regulation (EU) 2017/625 on official controls [1]. This PT, managed in line with ISO 17043:2010 [2], was open to National Reference Laboratories (NRLs) and EU official control laboratories (OCLs). Few additional officially appointed laboratories from outside the EU were accepted as well.
Two proficiency test items were distributed to participants to assess the efficacy of GMO analysis in meat paté contaminated with soybean (T1) and in maize flour (T2).
All but one of the 51 laboratories who tested T1 identified the MON89788 soybean event, while all of the 58 laboratories who tested T2 identified the T25 maize event. The majority of the quantitative results reported for T1 were slightly below the assigned value, but did not deviate more than 50 % from it. For T2, 33 results were scored as satisfactory, 2 as questionable and 15 (30 %) as unsatisfactory. Thirteen of the unsatisfactory results were overestimated by a factor of 2 to 5, thus requiring further investigations.
More than 84 % of the participants correctly evaluated the compliance status of the two test items based on their reported measurement results.
