  • Deadline for submission of data: 31/05/2019

Background

According to Regulation (EC) No 1333/2008[1], food additives which were permitted for use in the European Union before 20 January 2009 need to be re-evaluated by the European Food Safety Authority (EFSA). The programme for this re-evaluation is defined by Regulation (EU) No 257/2010[2].

EFSA has issued a scientific opinion on the safety of calcium carbonate (E 170) when used as food additive[3] in food categories specified in Annex II to Regulation (EC) No 1333/2008, exempting those for infants below 12 weeks of age. The reason was that the risk assessment approach followed at the time by the former EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS Panel) in the re-evaluation of food additives did not apply to this age group[4]. The ANS Panel has, therefore, specified in its opinion that the re-evaluation of uses for this particular age group will be performed separately.

On 31 May 2017, EFSA’s Scientific Committee (SC) published a guidance document[5] on the risk assessment of substances present in food intended for infants below 16 weeks of age, enabling the assessment of the safe use of calcium carbonate (E 170) and of other food additives for the population group below that age.

Following the latest advice from the EFSA’s Scientific Committee (SC) published guidance document[5], the risk assessment to be performed will address the safety of uses of calcium carbonate (E 170) in foods for infants below 16 weeks of age.

In addition, the ANS Panel identified in the conclusions and recommendations of its published opinion on calcium carbonate (E 170) data gaps in the risk assessment, relevant for all population groups.

For the sake of efficiency, the European Commission asked EFSA to address the above lack of data (data gaps) during its risk assessment of food additives for uses in food for young infants. Therefore specific data requirements for all uses of calcium carbonate (E 170) are included in this call for data.

EFSA will consider the relevance of the information provided for the risk assessment of calcium carbonate (E 170). The submission of the requested information is without prejudice to the final opinion of the Panel.

According to Article 6(5) of Regulation (EU) No 257/2010 where the requested information has not been submitted to EFSA within the set deadlines, the food additive may be removed from the Union list in accordance with the procedure laid down in Article 10.3 of Regulation (EC) No 1333/2008.

Overall objective

The purpose of this call for data is to offer interested parties (IPs) the opportunity to submit documented information (published, unpublished or newly generated) relevant to the re-evaluation of calcium carbonate (E 170) to be used in foods for infants below 16 weeks of age, as well as to address the data gaps that have been identified for all population groups in the already published EFSA opinion on this food additive.

Deadline for submission of data and disclosure of contact details

Interested parties and stakeholders should provide earlier or at the latest by 31/05/2019 the information described below.

Within 6 weeks from the publication of this call, please communicate in writing by e-mail to: fip [at] efsa.europa.eu, your availability to submit the requested information by the timeline specified above or any proposal for a new deadline providing justified reasons. Depending on the replies received the final deadline will be communicated to you through e-mail and by updating the current call.

In accordance with Article 6(4) of the Regulation (EU) No 257/2010 the information not submitted within the final deadline will only exceptionally be considered and EFSA can finalise its opinions on the basis of the information already provided.

In order to facilitate the collaboration of all interested parties to provide the data needed, we are seeking your consent to disclose the name and address of your organisation/business to the other parties that have expressed an interest to provide the requested information. If you do not wish to make these contact details available, clearly indicate it in your first communication.

Information sought

EFSA invites business operators and other interested parties (governments, interested organisations, universities, research institutions, companies) to submit technical and toxicological data on calcium carbonate (E 170), as appropriate. This information will be used:

  • for the follow-up on issues that have been raised in the conclusions and recommendations of the Scientific Opinion on the re-evaluation of calcium carbonate (E 170) as a food additive by the former EFSA ANS Panel (EFSA Panel on Food Additives and Nutrient Sources added to Food) published in 2011[3].
  • for the risk assessment of calcium carbonate (E 170) in food for infants below 16 weeks of age in the food categories 13.1.5.1 (Dietary foods for infants for special medical purposes and special formulae for infants). Data to be submitted should be in line with the EFSA Guidance of the Scientific Committee on the risk assessment of substances present in food intended for infants below 16 weeks of age[5]

    A. Information regarding the follow up of the conclusions and the recommendations for calcium carbonate (E 170) for uses in all population groups (EFSA ANS Panel, 2011)[3]

With reference to the conclusions and recommendations in the Scientific Opinion on the re-evaluation of calcium carbonate (E 170) as a food additive by the former EFSA ANS Panel (EFSA Panel on Food Additives and Nutrient Sources added to Food) published in 2011[3] information for calcium carbonate (E 170) is sought on:

1. Technical data

The characterisation of all the different commercial preparations of the food additive calcium carbonate (E 170) from five non- consecutive batches of each preparation, in relation to:

  • analytical data on current levels of lead, mercury, cadmium and arsenic in commercial samples of the food additive;
  • the lowest technologically achievable level for aluminium, lead, mercury, cadmium, and arsenic in order to adequately define their maximum limits in the specifications;
  • Because of their potential importance in toxicokinetics and toxicological effects, particle size and particle size distribution should be included in the EU specifications for the food additive calcium carbonate (E 170) in Commission Regulation (EU) No 231/2012. Detailed and comprehensive proposed specifications for the characterisation of the fraction of nanoparticles present in the food additive calcium carbonate (E 170) should be submitted. Information on particle size and particle size distribution for the food additive calcium carbonate (E 170) supported by analytical data, in line with the “EFSA guidance on the risk assessment of the application of nanoscience and nanotechnologies in the food and feed chain: Part 1, human and animal health”[1], is requested. This should allow the establishment of parameters in the EU specifications for calcium carbonate (E 170) that fully characterise the material used as a food additive. The analyses should be performed with appropriate analytical methods. EFSA seeks specific data on the methods of analysis used. These include but are not limited to e.g. the principle of the method, the scope of the method (i.e. the range of sample types that the method is used for), the concentration units used to express the analytical result(s), validation of the method (in particular limit of detection (LOD) and (LOQ).

2. Literature searches

Literature searches relevant for the safety evaluation of calcium carbonate (E 170) for all uses in foods for all population groups from 05/07/2011 up to the date of the data submission, should be conducted as described in the Guidance for submission for food additive evaluations (section 5.3)[4].

B. Information required for the risk assessment of calcium carbonate (E 170) for uses in foods for infants below 16 weeks of age

1. Technical data

For the uses of calcium carbonate (E 170) in the infant formulae for use in special formulae used for infants below 16 weeks of age under special medical conditions (FC 13.1.5.1), EFSA seeks information on:

  • the levels of use of calcium carbonate (E 170), as well as analytical data on the concentration of calcium carbonate in these formulae,
  • the fate and the reaction products of calcium carbonate (E 170) in the formula ready to use,
  • particular specification requirements for identity and the purity of calcium carbonate (E 170) (e.g. with respect to lead, aluminium and other toxic elements). This includes data on physical characterisation regarding the particle size as requested in part A.1 in the food additive and the formulae as consumed.

2. Toxicological data

Within the frame of the EFSA Guidance of the Scientific Committee on the risk assessment of substances present in food intended for infants below 16 weeks of age[5]the following information on the toxicological properties of calcium carbonate (E 170) and its adverse effects relevant for its use in special formulae used for infants below 16 weeks of age under special medical conditions (FC 13.1.5.1):

  • post-marketing surveillance reports on undesired and adverse reactions indicating the ages and other relevant data of the exposed infants and young children and the use level of calcium carbonate (E 170) in the marketed products;
  • published and unpublished case reports (e.g. available nutrivigilance data) on undesired and adverse effects, associated with the oral administration of calcium carbonate in any form to infants and young children.

 

3. Literature searches

Literature searches should be conducted relevant for the safety evaluation of calcium carbonate (E 170) when used in foods for infants below 16 weeks of age, as described in the Guidance for submission for food additive evaluations (section 5.3)[4].

Confidentiality

According to article 8 of Regulation (EU) No 257/2010 setting up a re-evaluation programme of approved food additives, confidential treatment may be given to information the disclosure of which might significantly harm the competitive position of business operators or other interested parties.

Therefore, the business operators and/or the interested parties should indicate which information wish to be treated as confidential and provide verifiable justification supporting this request. Note that the information described in article 8(2) of the Regulation (EU) No 257/2010 cannot be confidential.

In application of Article 8(4) of Regulation (EU) 257/2010, following a proposal from EFSA, the Commission will decide after consulting the interested business operator and/or the other interested parties, which information may remain confidential.
