Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on pasteurised Akkermansia muciniphila as a novel food (NF) pursuant to Regulation (EU) 2015/2283. A. muciniphila is a well-characterised non-toxin producing, avirulent microorganism that has been reported as part of normal gut microbiota. The NF, pasteurised A. muciniphila, is proposed by the applicant to be used as a food supplement at max. 5 × 1010 cells/day by adults excluding pregnant and lactating women, and in foods for special medical purposes. The Panel considers that the production process of the NF is sufficiently described and that the information provided on the composition of the NF is sufficient for its characterisation. Taking into account the composition of the NF and the proposed conditions of use, the consumption of the NF is not nutritionally disadvantageous. Based on literature data, and by applying an uncertainty factor of 200 to the no observed adverse effect level (NOAEL) of a 90-day repeated dose oral toxicity study in rats, the Panel concludes that the consumption of 3.4 × 1010 cells/day is safe for the target population under the provision that the number of viable cells in the NF is < 10 colony forming units (CFU)/g (i.e. limit of detection).
