# Commission Implementing Regulation (EU) No 503/2013 of 3 April 2013 on applications for authorisation of genetically modified food and feed in accordance with Regulation (EC) No 1829/2003 of the European Parliament and of the Council and amending Commission Regulations (EC) No 641/2004 and (EC) No 1981/2006 (Text with EEA relevance), Division 1.3: Comparative analysis

Extent: E+W+S+N.I.

The comparative analysis of composition and agronomic as well as phenotypic characteristics shall constitute, together with the molecular characterisation, the starting point to structure and conduct the risk assessment of a new genetically modified food and feed.
It shall aim at identifying similarities and differences:
(a)in composition, agronomic performance and phenotypic characteristics (intended and unintended alterations) between the genetically modified plant and its conventional counterpart;
(b)in composition between the genetically modified food and feed and its conventional counterpart.
Where no appropriate conventional counterpart can be identified, a comparative safety assessment cannot be made and consequently a safety and nutritional assessment of the genetically modified food or feed shall be carried out as for novel foods falling within the scope of Regulation (EC) No 258/97 of the European Parliament and of the Council that do not have conventional counterparts (such as where the genetically modified food or feed is not closely related to a food or feed with a history of safe use or where a specific trait or specific traits are introduced with the intention of bringing complex changes in the composition of the genetically modified food or feed).
