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 the safety and efficacy of monosodium l‐glutamate monohydrate produced by fermentation using Corynebacterium glutamicum KCCM 80188 when used as a sensory additive (flavouring compound) in feed and water for drinking for all animal species. The production strain is not genetically modified. Viable cells of the production strain were not detected in the final additive. The additive does not give rise to any safety concern regarding the production strain. Monosodium l‐glutamate monohydrate produced using C. glutamicum KCCM 80188 is considered safe for the target species, for the consumer and for the environment. Monosodium l‐glutamate monohydrated produced by C. glutamicum KCCM 80188 is considered not toxic by inhalation, not irritant to skin or eyes and not a dermal sensitiser. The FEEDAP Panel expressed reservations on the use of the additive in water for drinking due to concerns on its impact on the hygienic conditions of the water. The Panel concluded that the additive is efficacious to contribute to the flavour of feed.
