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.
