Abstract: The identification of suitable sample sizes for reliable detection of contaminants, including genetically modified (GM) materials, in kernel lots is a key issue in order to make inferences on entire consignments, typically characterized by non-random distribution of such contaminants (Lischer, 2001; Paoletti et al., 2003a; Paoletti et al., 2006). A theoretical model defining sampling strategies for non-randomly distributed GMO testing was developed (Paoletti et al., 2003b) and used for the establishment of ad hoc sampling plans for GMO testing (EC Rec. 787/2004; prCEN/TS 21568). Simulation studies implementing such model indicated that a minimum number of 20 increment samples is necessary to ensure reliable representation of the lot in case of low/medium levels of heterogeneity (Paoletti et al., 2003b).
