22、 Correct sampling is an operation that requires the most careful attention. Emphasis should be laid on the necessity of obtaining a representative sample of the goods under investigation. If ad-hoc sampling of food products is undertaken without applying a sampling strategy and without considering t
23、he lot specific properties, the analytical result is only valid for the sample that has been analysed. It is not possible to extend the result to the rest of the lot. By applying sampling strategies to assess the level of compliance of a given lot of products, a certain number of samples is taken, a
24、nd the result of the analysis can be extended to the whole lot. The use of sampling strategies is the only effective way to make correct statements about the nature, in this case the GMO-content, of the product tested. This Technical Specification has been established for food products, but could al
