Safety and efficacy of a feed additive consisting of l-leucine produced with Corynebacterium glutamicum KCCM 80421 for all animal species (CJ Europe GmbH)

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of l‐leucine produced with a genetically modified strain of Corynebacterium glutamicum (KCCM 80421) when used as nutritional (amino acid) and/or sensory (flavouring compound) feed additive in feed and water for drinking for all animal species and categories. The l‐leucine manufactured by fermentation with C. glutamicum KCCM 80421 did not give rise to any safety concern regarding the genetic modifications of the production strain.
