7 Prospects

Currently available methods for detecting GMOs are almost exclusively based on PCR. The predominance of this technique is likely to persist due to its broad applicability (mainly based on the chemical stability of DNA), the tremendous experience which has already been gained with it and the high potential for automation. However, other techniques are currently being tested in projects which seek to develop detection procedures for GMOs. New results may recommend the use of some of these techniques for specialised applications.

In order to prevent food control expenses from escalating, it is desirable that inexpensive and widely applicable screening methods for the detection of food derived from genetic engineering are developed. With the increasing number of commercially sold GMO products these screening methods are likely to be complemented by product-specific detection methods.

National and international coordination of the development of methods to identify GMOs would be highly appreciated. A comprehensive database containing all national approvals of GMOs with the respective genetic and sequence information is bound to promote greater research efficiency in this area. In this respect, it should be noted that the database on which the tables and statistics shown in this report are based will be developed further and partially integrated into the database of an ongoing EC project (DMIF-GEN). The expansion of the database on subjects such as environmental and consumer safety information is planned on a modular basis. This information should provide a basis for the efficient development of identification methods by expert groups, help to assess the safety of genetically engineered food and facilitate information transfer to the consumer and the general public on genetically modified products.
