部分原文報導如下：
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 l‐valine produced by fermentation using a non‐genetically modified strain of Corynebacterium glutamicum (CGMCC 7.358). The additive is intended to be used in feed and water for drinking for all animal species and categories. The production strain meets the qualifications for the qualified presumption of safety (QPS) approach to safety assessment and is considered safe. l‐Valine produced using C. glutamicumCGMCC 7.358 is safe for the target species when supplemented in appropriate amounts to the diet according to the nutritional needs of the target species, for the consumer and for the environment. No conclusion could be drawn on the potential of l‐valine produced using C. glutamicumCGMCC 7.358 to be toxic by inhalation, irritant to the skin or eyes, or a dermal sensitiser due to the lack of data. The product l‐valine produced by fermentation using C. glutamicumCGMCC 7.358 is regarded as an efficacious source of the essential amino acid l‐valine for non‐ruminant nutrition. For the supplemental l‐valine to be as efficacious in ruminants as in non‐ruminant species, it requires protection against degradation in the rumen.
