authorising the placing on the market of 6′-Sialyllactose sodium salt produced by derivative strain of Escherichia coli W (ATCC 9637) as a novel food and amending Implementing Regulation (EU) 2017/2470
(Text with EEA relevance)


THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,


Having regard to Regulation (EU) 2015/2283 of the European Parliament and of the Council of 25 November 2015 on novel foods, amending Regulation (EU) No 1169/2011 of the European Parliament and of the Council and repealing Regulation (EC) No 258/97 of the European Parliament and of the Council and Commission Regulation (EC) No 1852/2001 (1), and in particular Article 12(1) thereof,

Whereas:







(1)


Regulation (EU) 2015/2283 provides that only novel foods authorised and included in the Union list of novel foods may be placed on the market within the Union.












(2)


Pursuant to Article 8 of Regulation (EU) 2015/2283 Commission Implementing Regulation (EU) 2017/2470 (2) has established a Union list of novel foods.












(3)


Commission Implementing Regulation (EU) 2021/82 (3) authorised the placing on the Union market of 6′-Sialyllactose (‘6′-SL’) sodium salt obtained by microbial fermentation using the genetically modified Escherichia coli (‘E. coli’) strain K12 DH1 as a novel food under Regulation (EU) 2015/2283.












(4)


Commission Implementing Regulation (EU) 2023/948 (4) authorised the placing on the Union market of 6′-SL sodium salt produced by derivative strains of E. coli BL21(DE3) as a novel food under Regulation (EU) 2015/2283.












(5)


On 26 March 2021, the company Kyowa Hakko Bio Co., Ltd (‘the applicant’) submitted an application for an authorisation to the Commission in accordance with Article 10(1) of Regulation (EU) 2015/2283 to place 6′-SL sodium salt, obtained by microbial fermentation using a genetically modified strain derived from the host strain E. coli W (ATCC 9637), on the Union market as a novel food. The applicant requested for 6′-SL sodium salt so produced to be used in unflavoured pasteurised and unflavoured sterilised milk products, unflavoured fermented milk-based products, flavoured milk-based products including heat-treated products, beverages (flavoured drinks excluding drinks with a pH less than 5), cereal bars, infant formula and follow-on formula as defined in Regulation (EU) No 609/2013 of the European Parliament and of the Council (5), processed cereal-based food and baby food for infants and young children as defined in Regulation (EU) No 609/2013, milk-based drinks and similar products, total diet replacement foods for weight control as defined in Regulation (EU) No 609/2013, foods for special medical purposes as defined in Regulation (EU) No 609/2013, and in food supplements as defined in Directive 2002/46/EC of the European Parliament and of the Council (6) intended for the general population. Subsequently, on 19 June 2023, the applicant modified the initial request in the application on the use of 6′-SL sodium salt produced with the derivative strain of E. coli W (ATCC 9637) in food supplements to exclude infants and young children. With regard to conditions of use, the applicant also proposed that food supplements containing 6′-SL sodium salt produced with the derivative strain of E. coli W (ATCC 9637) should not be consumed if other foods with added 6′-SL sodium salt are consumed the same day.












(6)


On 26 March 2021, the applicant also made a request to the Commission for the protection of proprietary scientific studies and data, namely, liquid chromatography-mass spectrometry (‘LC-MS/MS’), nuclear magnetic resonance (‘NMR’) and a high-performance liquid chromatography – charged aerosol detection (‘HPLC-CAD’) studies for the determination of the identity of 6′-SL (7); a description of the genetically modified 6′-SL sodium salt production strain (8); a detailed description of the production process (9); a bacterial reverse mutation test with 6′-SL sodium salt (10); an in vitro mammalian cell micronucleus test with 6′-SL sodium salt (11); an in vivo mammalian cell micronucleus test with 6′-SL sodium salt (12); an in vivo mammalian cell micronucleus test with 3′-Sialyllactose (‘3′-SL’) sodium salt (13); a bacterial reverse mutation test with 3′-SL sodium salt (14); a 90-day oral toxicity study in rats with 3′-SL sodium salt (15); a bioinformatics analysis study on the genome of the E. coli W (ATCC 9637) to detect heterologous sequences that could encode possible allergens (16); and, a 90-day oral toxicity study in rats with 6′-SL sodium salt (17), submitted in support of the application.












(7)


In accordance with Article 10(3) of Regulation (EU) 2015/2283, on 7 December 2021, the Commission requested the European Food Safety Authority (‘the Authority’) to carry out an assessment of 6′-SL sodium salt obtained by microbial fermentation using a genetically modified strain of E. coli W (ATCC 9637), as a novel food.












(8)


On 27 April 2023, the Authority adopted its scientific opinion on the ‘Safety of 6′-sialyllactose (“6′-SL”) sodium salt produced by a derivative strain (Escherichia coli NEO6) of Escherichia coli W (ATCC 9637) as a novel food pursuant to Regulation (EU) 2015/2283’ (18), in accordance with the requirements of Article 11 of Regulation (EU) 2015/2283.












(9)


In its scientific opinion, the Authority concluded that 6′-SL sodium salt is safe under the proposed conditions of use and for the proposed target populations. Therefore, that scientific opinion gives sufficient grounds to establish that 6′-SL sodium salt produced with derivative strain of Escherichia coli W (ATCC 9637), when used in in unflavoured pasteurised and unflavoured sterilised milk products, unflavoured fermented milk-based products, flavoured milk-based products including heat-treated products, beverages (flavoured drinks excluding drinks with a pH less than 5), cereal bars, infant formula and follow-on formula as defined in Regulation (EU) No 609/2013, processed cereal-based food and baby food for infants and young children as defined in Regulation (EU) No 609/2013, milk-based drinks and similar products, total diet replacement foods for weight control as defined in Regulation (EU) No 609/2013, foods for special medical purposes as defined in Regulation (EU) No 609/2013, and in food supplements as defined in Directive 2002/46/EC, complies with the authorisation requirements of Article 12(1) of Regulation (EU) 2015/2283.












(10)


In its scientific opinion, the Authority noted that its conclusion on the safety of the novel food was based on scientific studies and data from namely, LC-MS/MS, NMR and HPLC-CAD studies for the determination of the identity of 6′-SL; the description of the genetically modified 6′-SL sodium salt production strain; the detailed description of the production process; the bacterial reverse mutation test with 6′-SL sodium salt; the in vitro mammalian cell micronucleus test with 6′-SL sodium salt; the in vivo mammalian cell micronucleus test with 6′-SL sodium salt; a bioinformatics analysis study on the genome of the E. coli W (ATCC 9637) to detect heterologous sequences that could encode possible allergens; a 90-day oral toxicity study in rats with 6′-SL sodium salt, contained in the applicant’s file, without which it could not have assessed the novel food and reached its conclusion.












(11)


The Commission requested the applicant to further clarify the justification provided with regard to its proprietary claim over those scientific studies and data, and to clarify its claim to an exclusive right of reference to them in accordance with Article 26(2)(b) of Regulation (EU) 2015/2283.












(12)


The applicant declared that it held proprietary and exclusive rights of reference to the scientific studies and data, namely, LC-MS/MS, NMR and HPLC-CAD studies for the determination of the identity of 6′-SL; the description of the genetically modified 6′-SL sodium salt production strain; the detailed description of the production process; the bacterial reverse mutation test with 6′-SL sodium salt; the in vitro mammalian cell micronucleus test with 6′-SL sodium salt; the in vivo mammalian cell micronucleus test with 6′-SL sodium salt; a bioinformatics analysis study on the genome of the E. coli W (ATCC 9637) to detect heterologous sequences that could encode possible allergens; and, the 90-day oral toxicity study in rats with 6′-SL sodium salt, under national law at the time they submitted the application and that third parties cannot lawfully access, use or refer to those data and studies.












(13)


The Commission assessed all the information provided by the applicant and considered that the applicant has sufficiently substantiated the fulfilment of the requirements laid down in Article 26(2) of Regulation (EU) 2015/2283. Therefore, the scientific studies and data submitted in support of the application, namely, LC-MS/MS, NMR and HPLC-CAD studies for the determination of the identity of 6′-SL; the description of the genetically modified 6′-SL sodium salt production strain; the detailed description of the production process; the bacterial reverse mutation test with 6′-SL sodium salt; the in vitro mammalian cell micronucleus test with 6′-SL sodium salt; the in vivo mammalian cell micronucleus test with 6′-SL sodium salt; a bioinformatics analysis study on the genome of the E. coli W (ATCC 9637) to detect heterologous sequences that could encode possible allergens; and, the 90-day oral toxicity study in rats with 6′-SL sodium salt, should be protected in accordance with Article 27(1) of Regulation (EU) 2015/2283. Accordingly, only the applicant should be authorised to place 6′-SL sodium salt produced with derivative strain of E. coli W (ATCC 9637) on the market within the Union during a period of five years from the entry into force of this Regulation.












(14)


However, restricting the authorisation of 6′-SL sodium salt produced with derivative strain of E. coli W (ATCC 9637) and the reference to the scientific studies and data contained in the applicant’s file for the sole use by them does not prevent subsequent applicants from applying for an authorisation to place on the market the same novel food provided that their application is based on legally obtained information supporting such an authorisation.












(15)


In line with the conditions of use of food supplements containing 6′-SL sodium salt produced with derivative strain of E. coli W (ATCC 9637), as proposed by the applicant, it is necessary to inform consumers by appropriate labelling that food supplements containing 6′-SL sodium salt should not be consumed by infants and children under 3 years of age and should not be used if other foods with added 6′-SL sodium salt are consumed the same day.












(16)


It is appropriate that the inclusion of 6′-SL sodium salt produced with derivative strain of E. coli W (ATCC 9637) as a novel food in the Union list of novel foods contains also the required conditions of use, specifications and other information related to its authorisation, as referred to in Article 9(3) of Regulation (EU) 2015/2283.












(17)


6′-SL sodium salt produced with derivative strain of E. coli W (ATCC 9637) should be included in the Union list of novel foods set out in Implementing Regulation (EU) 2017/2470. The Annex to Implementing Regulation (EU) 2017/2470 should therefore be amended accordingly.












(18)


The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on Plants, Animals, Food and Feed,





HAS ADOPTED THIS REGULATION:
