This document specifies a procedure for the detection of the DNA transition sequence between the 35S promoter region from cauliflower mosaic virus (P35S) and the neomycin-phosphotransferase gene (nptII) from the Tn5 transposon of Escherichia coli. The P35S-nptII segment is part of a construct which confers resistance to neomycin/kanamycin antibiotics frequently found in genetically modified (GM) plants. The detection method is based on real-time PCR and can be used for qualitative screening purposes. For identification and quantification of a specific GM plant (event) a follow-up analysis has to be carried out. This method is applicable for the analysis of DNA extracted from foodstuffs. It can also be suitable for the analysis of DNA extracted from other products such as feedstuffs and seeds. The application of this method requires the extraction of an adequate amount of amplifiable DNA from the relevant matrix.

This document specifies procedures for DNA extraction from alfalfa (Medicago sativa) seeds and for the specific detection of the herbicide-tolerant alfalfa events J101 and J163 and the lignin-modified alfalfa event KK179 in crop/plant/seed/grain test samples. The detection methods are based on real-time PCR and are targeting the DNA transition sequences between the alfalfa genome and the respective integrated gene construct. The methods can be applied for direct event-specific identification or as a follow-up analysis, if sequences encoding the promoter of the Figwort mosaic virus (P-FMV), the terminator of the nopaline synthase gene from Rhizobium radiobacter (T-nos), or the construct CTP2/CP4-EPSPS (herbicide tolerance) were detected by screening analyses of test samples. In this document, the methods were validated using ground alfalfa seeds and DNA extracted thereof. The PCR methods are also applicable for the analysis of other matrices such as feed and foodstuffs. The application of these PCR methods requires the extraction of an adequate amount of amplifiable DNA from the relevant matrix.

This document specifies a procedure for the detection of a DNA sequence of the open reading frame five (ORF V) from cauliflower mosaic virus (CaMV) and a procedure for the detection of the DNA sequence of the nopaline synthase (nos) gene from tumour-inducing (Ti) plasmids of phytopathogenic Rhizobium radiobacter (formerly named Agrobacterium tumefaciens). The procedures can be used in the context of screening for genetically modified crop/plants and their derived products to further clarify a positive PCR result for a specific promoter or terminator of CaMV (P-35S, T-35S), or both, and the nos gene (P-nos, T-nos), respectively. The methods specified in this document will detect and identify naturally occurring CaMV or Rhizobium radiobacter (Ti plasmid) DNA, or both, if present in the sample in the absence of a genetically modified plant event containing the specified target sequences. Both methods are based on the real-time polymerase chain reaction (PCR) and are applicable for the analysis of DNA extracted from foodstuffs and other products such as feedstuffs and seeds/grains. The application of the methods requires the extraction of an adequate amount of amplifiable DNA from the relevant matrix. With appropriate calibration material, the CaMV ORF V or nos copy number, or both, can be estimated and compared, respectively, with the estimated copy number for the promoter (P-35S, P-nos) or the terminator (T-35S, T-nos) sequences, or both. Thereby, conclusions are possible about the presence of an unknown genetically modified organism (GMO) in addition to any detected CaMV DNA or Rhizobium radiobacter Ti plasmid DNA, or both, in a test sample.

This document describes a method using isotopically labelled standards for the quantitative determination of aflatoxins B1, B2, G1, G2 and M1 (AFB1, AFB2, AFG1, AFG2 and AFM1), ochratoxin A (OTA), deoxynivalenol (DON), zearalenone (ZEN), T-2 and HT-2 toxins (T-2 and HT-2) and fumonisins B1 and B2 (FB1 and FB2) in foods by liquid chromatography (LC) coupled with tandem mass spectrometry (MS/MS).
A specific immunoaffinity column (IAC) clean-up is needed for aflatoxins (AFs) and OTA in food intended for infants and young children (e.g. infant cereals, milk-based powders), in spices, in dried fruits and in nuts.
The method has been validated through an intercollaborative study on different commodity groups: cereals and cereal-based products including food for infant and young children, nuts, spices, dried fruits and milk powder. The measuring range of each mycotoxin in these naturally contaminated and/or spiked food samples were:
- AFB1: 0,085 7 µg/kg - 11,4 µg/kg;
- AFB2: 0,079 2 µg/kg - 12,5 µg/kg;
- AFG1: 0,062 8 µg/kg - 20,9 µg/kg;
- AFG2: 0,052 0 µg/kg - 15,0 µg/kg;
- AFM1: 0,034 2 µg/kg - 0,110 µg/kg;
- OTA: 0,448 µg/kg - 17,2 µg/kg;
- DON: 45,2 µg/kg - 743 µg/kg;
- ZEN: 9,57 µg/kg - 131 µg/kg;
- T-2: 10,3 µg/kg - 57,9 µg/kg;
- HT-2: 9,50 µg/kg - 81,8 µg/kg;
- FB1: 31,1 µg/kg - 4 260 µg/kg;
- FB2: 44,2 µg/kg - 1 300 µg/kg.
The measuring ranges of the method for each mycotoxin/matrix combination are given in Table 8.
