Safety and efficacy of vitamin B2 (riboflavin 5′‐phosphate ester monosodium salt) for all animal species when used in water for drinking

Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on vitamin B2 in the form of riboflavin 50-phosphate ester monosodium salt as an additive for all animal species for use in water for drinking. The additive under assessment is obtained from a source of riboflavin produced by Ashbya gossypii. No information was provided on the identity and characterisation of the production strain, and on whether or not it is a genetically modified microorganism. Therefore, in the absence of adequate information, it is not possible to perform an assessment of the safety of the production strain. Riboflavin 50-phosphate ester monosodium salt \u2018per se\u2019 is considered safe for the target animals, consumers and the environment. In the absence of data regarding the identity and characterisation of the production strain, the FEEDAP Panel cannot conclude on the safety for the target species, consumers, users and the environment of the riboflavin 50-phosphate ester monosodium salt under assessment. Similarly, in the absence of data, no conclusion can be reached on the safety of the product for the users. Riboflavin 50-phosphate ester monosodium salt is regarded as effective in covering the animal\u2019s requirement when administered via water for drinking
