Call for data relevant to the safety assessment of Astaxanthin in the framework of Regulation 2283/2015
- Published: 25/07/2018
- Deadline for registering interest for submission: 20/09/2018
- Deadline for submission of data: 20/12/2018
- Updated deadline for submission of data: 15/02/2019
In 2014, the EFSA NDA Panel assessed the safety of the Novel Food (NF) astaxanthin-rich ingredient derived from microalgae Haematococcus (H.) pluvialis in the context of an application submitted under Regulation (EC) No 258/1997 (EFSA NDA Panel, 2014a). In that Opinion, the Panel noted that the proposed maximum daily intake of 4 mg (0.06 mg/kg bodyweight (bw) for an adult weighing 70 kg) exceeded the acceptable daily intake (ADI) for astaxanthin of 0.034 mg/kg bw per day (corresponding to approximately 2.4 mg for an adult person). This ADI was established by the EFSA FEEDAP Panel (2014b) and was based on a benchmark dose (BMD) lower confidence limit for a 10 % extra risk (BMDL10) calculated for the liver hypertrophy observed in female rats in a chronic toxicity/carcinogenicity study with synthetic astaxanthin and by applying an uncertainty factor of 100 to the BMDL10 of 3.4 mg/kg bw. In this study statistically significant increased incidences of hepatocellular vacuolation, hepatocellular hypertrophy and multinuclear hepatocytes were observed in female rats at all tested dose levels (i.e. 40, 200 and 1,000 mg synthetic astaxanthin per kg bw). Also statistically significant increased incidences of hepatocellular adenomas in females were reported for the mid and high dose groups of female rats in this study. The absence of genotoxicity of astaxanthin was noted in both EFSA Opinions from 2014.
In a mandate dated 27/02/2018, the European Commission (EC) informed EFSA that under Commission Implementing Regulation (EU) 2017/2470 establishing the Union list of authorised novel foods in accordance with Regulation (EU) 2015/2283, an astaxanthin-rich ingredient from H. pluvialis algae is authorised in food supplements at levels of up to 40-80 mg/day, which correspond to a maximum authorised level of 8 mg astaxanthin per day. The EC also informed that since 1995 when astaxanthin was granted authorisation in food supplements at the maximum level of 8 mg/day in Sweden, a number of notifications of astaxanthin pursuant to Article 5 of Regulation (EC) No 258/1997 on novel foods were sent to the EC.
In accordance with Article 29(1) of Regulation (EC) No 178/2002, the EC tasked EFSA to evaluate whether the safety of astaxanthin used as a NF in food supplements at maximum levels of 8 mg/day is still in accordance with the requirements of Regulation (EU) 2015/2283, taking into account the overall, cumulative intakes of astaxanthin from all sources, including from its approved uses in food supplements and in other foods. In doing so, EFSA should solicit and make use of the most recent toxicological and exposure evidence which may be available to business operators and in the public domain.
The purpose of this call for data is to provide the opportunity for stakeholders and other interested parties to submit studies (published, unpublished or newly generated) relevant for the evaluation of the safety of astaxanthin. In particular, EFSA seeks data which may be suitable to confirm or amend the ADI established by EFSA in 2014.
Deadline for submission of data and disclosure of contact details
Interested parties and stakeholders should provide by the updated deadline of 15/02/2019 the information described below.
To assist our planning for assessment purpose, if you intend to supply information after 20/09/2018 please e-mail to nda_callfordata [at] efsa.europa.eu (nda_callfordata[at]efsa[dot]europa[dot]eu) your intention to submit the requested information within 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.
Information not submitted within the final deadline will only exceptionally be considered and EFSA can decide to finalise its opinion solely on the basis of the information provided within the final deadline (15/02/2019).
In order to facilitate the collaboration of all interested parties to provide the data needed, we are seeking your consent to disclose your personal data (name, e-mail address and telephone number) to the other parties that have expressed an interest to provide the requested information. If you do not wish to make your contact details available, clearly indicate it in your first communication.
EFSA kindly invites business operators and other interested parties (governments, interested organisations, universities, research institutions, and companies) to submit data concerning astaxanthin in relation to:
- its natural occurrence in foods other than food supplements;
- intake estimates (oral exposure) in humans;
- kinetic studies (absorption, distribution, metabolism, excretion) in rats and humans;
- mechanistic studies, in particular regarding hepatic adverse effects of astaxanthin;
- animal toxicity studies, particularly chronic and carcinogenicity studies, human data, in particular studies which included liver-related endpoints (e.g. blood markers such as liver enzymes, bilirubin, total protein, albumin, triglycerides, cholesterol, urea nitrogen, activated partial thromboplastin and prothrombin times);
- other information which may be relevant to confirm or amend the acceptable daily intake (ADI) established by EFSA in 2014.
(Note: EFSA does not seek studies on supposed potential benefits of astaxanthin for health)
In order to comply with its requirements for transparency as outlined in Article 38 of Regulation (EC) No 178/2002 as well as in Regulation (EU) No 2015/2283, EFSA has to disclose in its published scientific opinions data received/available which are considered essential for the scientific assessment, as well as background information supporting the relevant scientific reasoning. However, according to Article 39(1) of Regulation (EC) No 178/2002 EFSA may not divulge to third parties confidential information received for which confidential treatment has been requested, justified, and agreed, except for information which must be made public if circumstances so require, in order to protect public health, or whenever its conclusions highlight foreseeable adverse health effects. Furthermore, EFSA is subject to Regulation (EC) No 1049/2001 regarding public access to European Parliament, Council and Commission documents.
Therefore, business operators or interested parties submitting relevant datasets in response to this call are requested to proactively clearly identify as part of their submission all parts or bits of information or data they consider as deserving confidential treatment. For each item for which a claim for confidential treatment is submitted, the concerned individual has to provide verifiable justification supporting each claim by indicating the reasons and circumstances proving why the disclosure of these elements would cause them financial harm.
Confidential status ensures that EFSA does not disclose to the public the information or dataset to which it is granted.
A decision is taken by EFSA on each confidentiality claim submitted by concerned individuals. Confidential status may be granted to information the disclosure of which might significantly harm the competitive position of business operators or other interested parties.
Interested business operators or other interested parties will be informed by EFSA about which information or data will be granted confidential treatment, and on the legal remedies available thereto should a decision rejecting their confidentiality claims be taken.
