　　Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of disodium 5’-guanylate produced by fermentation with Corynebacterium stationis KCCM 10530 and Escherichia coli K-12 KFCC 11067 when used as a sensory additive (flavouring compound) in feed and water for drinking for all animal species. The additive does not raise safety concerns under the proposed conditions of use for the target species, consumers the users and the environment. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) expressed reservations on the use of the additive in water for drinking due to concerns on its impact on hygienic conditions of the water. The Panel concluded that the additive is efficacious to contribute to the flavour of feed.
