[Genetically modified organisms--problems and legislation].

Genetically modified organisms are defined by law as entities capable of replication and/or transmission of hereditary material that had been altered by the insertion or removal of a DNA fragment. By the EU legal regulation as well as by the Czech law, such organisms are considered risky whereas other products of breeding, though obtained by, e.g., induced mutagenesis, are claimed as safe. Organisms transferred from other ecosystems are also considered safe. The Czech law on the use of genetically modified organisms is based on registers of users and organisms for specific use. Application for the registration that is valid as an approval should be submitted to the Ministry of Environment. The applicant is obliged to present the risk assessment of the particular use of genetically modified organisms. Genetically modified organisms are connected with certain risk to ecology, however health risks are brought about almost exclusively by microorganisms. Modified organisms used for food production are thoroughly tested for substantial equivalency with standard crops and with respect to health parameters of the protein(s) newly introduced due to genetic modification. Detail tests as well as their cost are close to the testing of new drugs. European as well as Czech rules for food labelling are motivated by the psychology of consumers rather than by health impact. They result to absurdities but do not meet the task of public psychology. This is why the EU authorities are looking for measures to change the present situation that other wise would bring Europe well behind the developed countries.
