The distinction between three levels of substantial equivalence (plete, partial, non) of the novel food to its counterpart, and the subsequent decisions for further testing based upon substantial equivalence, are similar to those defined by OECD (1996). The Codex Alimentarius Commission of FAO/WHO is mitted to the international harmonization of food standards. Food standards developed by Codex Alimentarius should be adopted by the participating national governments. The Codex ad hoc Intergovern mental Task Force on Foods Derived from Biotechnology has the task to develop standards, guidelines and other remendations for geically modified foods. During its first session in Chiba (Japan) in March 2020 definitions were agreed concerning the ‘risk assessment’ and ‘risk analysis’ of geically modified foods. Risk assessment covers issues such as food safety, substantial equivalence and longterm health effects, while risk analysis may include decisionmaking and postmarket monitoring. An Expert Consultation held in Geneva, Switzerland in May/June 2020 evaluated experiences gathered since the 1996 Consultation. Topics considered included substantial equivalence, unintended effects of geic modification, food safety, 6 nutritional effects, antibiotic resistance marker genes, and allergenicity. The Consultation endorsed the concept of substantial equivalence as a pragmatic approach for the safety assessment of geically modified foods, and concluded that at present no suitable alternative strategies are available. Application of the concept is a starting point for safety assessment, rather than an endpoint. It identifies similarities and possible differences between the geically modified food and its appropriate counterpart, which should then be assessed further. The issue of the potential occurrence of unintended effects due to the geic modification process, such as the loss of existing traits or the acquisition of new ones, was examined. The occurrence of unintended effects is not unique for the application of recDNA techniques, but also occurs frequently in conventional breeding. Present approaches to detecting such effects focus on chemical analysis of known nutrients and toxicants (targeted approach). In order to increase the possibility of detecting unintended effects, profiling/fingerprinting methods are considered useful alt
