Description
The EFSA Panel on Additives and Products or Substances used in Animal Feed assesses in 2026 an amino acid made by fermentation for use in feed for every animal species. The product is l-leucine, produced by a genetically modified strain of Corynebacterium glutamicum, and requested both as a nutritional supplement and as a flavouring. The applicant is CJ Europe.
The panel found no safety concern from the genetic modification itself, and neither living production cells nor their DNA were detectable in the finished additive. Used in feed at levels matching animals' nutritional needs, or as a flavouring, the leucine was judged safe for the target species. One reservation stands out in the opinion: delivering the amino acid through drinking water raised concerns, a distinction feed formulators will need to respect.
