Abstract 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‐lysine sulfate produced by fermentation using Corynebacterium glutamicum KFCC 11043 when used as a nutritional additive in feed for all animal species. The active substance is l‐lysine. The production strain qualifies for the qualified presumption of safety (QPS) approach to safety assessment and was not detected in the final product. l‐Lysine sulfate produced using C. glutamicum KFCC 11043 does not pose any safety concern associated with the production strain. l‐Lysine sulfate produced by C. glutamicum KFCC 11043 is considered safe for the target species. When using l‐lysine sulfate, the background sulfur/sulfate content in the compound feed should be taken into account. l‐Lysine sulfate produced by C. glutamicum KFCC 11043 is safe for the consumer and for the environment. From the results of studies on the safety for the user of l‐lysine sulfate produced by a different production strain, it was possible to conclude on the safety for the user of the product under assessment. l‐Lysine sulfate produced by C. glutamicum KFCC 11043 is considered non‐toxic by inhalation, non‐irritant to skin or eyes and it is not a skin sensitiser. l‐lysine sulfate is considered as an efficacious source of the essential amino acid l‐lysine for non‐ruminant animal species. For the supplemental l‐lysine to be as efficacious in ruminants as in non‐ruminant species, it would require protection against degradation in the rumen.
