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)
When the UK left the EU, legislation.gov.uk published EU legislation that had been published by the EU up to IP completion day (31 December 2020 11.00 p.m.). On legislation.gov.uk, these items of legislation are kept up-to-date with any amendments made by the UK since then.
Legislation.gov.uk publishes the UK version. EUR-Lex publishes the EU version. The EU Exit Web Archive holds a snapshot of EUR-Lex’s version from IP completion day (31 December 2020 11.00 p.m.).
There are outstanding changes not yet made to Commission Implementing Regulation (EU) No 503/2013. Any changes that have already been made to the legislation appear in the content and are referenced with annotations.
Revised legislation carried on this site may not be fully up to date. Changes and effects are recorded by our editorial team in lists which can be found in the ‘Changes to Legislation’ area. Where those effects have yet to be applied to the text of the legislation by the editorial team they are also listed alongside the legislation in the affected provisions. Use the ‘more’ link to open the changes and effects relevant to the provision you are viewing.
For a particular food or feed material, the methodological steps shall include the methods for DNA extraction and the subsequent quantification in a real-time Polymerase Chain Reaction (PCR) System. In such a case, the whole process from extraction up to the PCR-technique shall constitute a method. The applicant shall provide information about the whole method.
In that case, the applicant shall provide experimental data from an in-house validation in which the method module has been successfully applied in the context of the application for authorisation.
The method(s) shall be specific to the transformation event (hereafter referred to as ‘event-specific’) and thus shall only be functional with the genetically modified organism or genetically modified based product considered and shall not be functional if applied to other transformation events already authorised; otherwise the method cannot be applied for unequivocal detection/identification/quantification. This shall be demonstrated with a selection of non-target transgenic authorised transformation events and conventional counterparts. This testing shall include closely related transformation events.
The method(s) shall be applicable to samples of the food or feed, to the control samples and to the certified reference material.
The applicant shall take into consideration the following documents for the development of the detection method:
Foodstuffs — Methods of analysis for the detection of genetically modified organisms and derived products — General requirements and definitions: ISO 24276;
Foodstuffs — Methods of analysis for the detection of genetically modified organisms and derived products — Nucleic acid extraction: ISO 21571;
Foodstuffs — Methods of analysis for the detection of genetically modified organisms and derived products — Quantitative nucleic acid based methods: ISO 21570;
Foodstuffs — Methods of analysis for the detection of genetically modified organisms and derived products — Qualitative nucleic acid based methods: draft European standard ISO 21569.
The method shall also take into consideration the more detailed requirements set out in the common criteria set by the EURL, and the ENGL for minimum performance requirements for analytical methods for GMO testing. These criteria are part of the guidance provided by the EURL.
The following points shall be clearly addressed by the applicant:
Scientific basis: the applicant shall provide an overview of the principles of how the method works. This overview shall include references to relevant scientific publications.
Scope of the method: the applicant shall indicate the matrix(es) (for example, processed food, raw materials), the type of samples and the percentage range to which the method may be applied.
Operational characteristics of the method: the required equipment for the application of the method shall be specified, with regard to the analysis as such and the sample preparation. Further information of any specific aspects crucial for the application of the method shall also be included.
Protocol: the applicant shall provide a complete optimised protocol of the method. The protocol shall present all the details as required to transfer and apply the method independently in other laboratories.
A prediction model (or a similar tool) needed to interpret results and to make inferences shall be described in full details. Instructions for the correct application of the model shall be provided by the applicant.
Breeding schemes that are to be applied for the production of genetically modified food and feed and their impact on the interpretation of results shall be provided by the applicant.
primer pairs tested and probe, if appropriate, including a justification as to how and why the proposed primer pair has been selected;
stability testing, which shall be established through the submission of experimental results from testing the method with different plant varieties;
specificity, which shall be established through the submission of the full sequence of the insert(s) in a standardised electronic format, together with the base pairs of the host flanking sequences so as to enable the EURL to assess the specificity of the proposed method by running homology searches in a molecular database;
precision, the relative repeatability standard deviation shall be less than or equal to 25 % related to mass fraction over the whole dynamic range of the method.
participating laboratories, time of the analysis and outline of the experimental design, including the details about the number of runs, samples, replicates, etc.;
description of the laboratory samples (such as size, quality, date of sampling), positive and negative controls as well as certified reference material, plasmids and alike used;
description of the approaches that have been used to analyse the test results and outliers;
any particular points observed during the testing;
references to relevant literature or technical provisions used in the testing.
For the purpose of implementing Articles 5(3)(j) and 17(3)(j) of Regulation (EC) No 1829/2003, the applicant shall, together with the information required under Sections 1, 2 and 3 of this Annex, also provide samples of the food and feed and their control samples of a type and amount to be specified by the EURL for the specific application for authorisation.
The information accompanying the control samples shall include information on the breeding of the plant which has been used for the production of the control samples and on the zygosity of the insert(s).
The applicant may use the same raw material for the production of certified reference material and for the production of control samples.

This timeline shows the different versions taken from EUR-Lex before exit day and during the implementation period as well as any subsequent versions created after the implementation period as a result of changes made by UK legislation.
The dates for the EU versions are taken from the document dates on EUR-Lex and may not always coincide with when the changes came into force for the document.
For any versions created after the implementation period as a result of changes made by UK legislation the date will coincide with the earliest date on which the change (e.g an insertion, a repeal or a substitution) that was applied came into force.
