　　Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of vitamin B12 (cyanocobalamin) produced by fermentation with a non-genetically modified strain of Ensifer adhaerens (CGMCC 21299), when used as a nutritional additive for all animal species. No viable cells or DNA of the production strain were detected in the additive. Therefore, cyanocobalamin produced by fermentation with E. adhaerens CGMCC 21299 does not raise safety concerns as regards to the production strain. The Panel on Additives and Products or Substances used in Animal Feed concluded that cyanocobalamin produced by fermentation with E. adhaerens CGMCC 21299 is considered safe for all animal species, for the consumers and the environment. Due to the presence of nickel, the additive is considered a skin and respiratory sensitiser. Inhalation and dermal exposure are considered a risk. Due to the lack of data, the Panel could not conclude on the potential of the additive to be an eye irritant. Cyanocobalamin produced by fermentation with E. adhaerens CGMCC 21299 is effective in meeting animal's nutritional requirements when administered via feed.
