Scientific Opinion on the safety for the target animals and for the users of selenium in the form of organic compounds produced by the selenium-enriched yeast Saccharomyces cerevisiae NCYC R645 (SelenoSource AF 2000) for all animal species

In 2011 the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) delivered an opinion on the safety and efficacy of SelenoSource AF 2000 which was inconclusive concerning the safety for target animals and safety for users/workers. In response to this, the applicant submitted additional information. A study supporting tolerance in chickens for fattening was provided; however, no new information on users’ safety was submitted. SelenoSource AF 2000 is considered to be a safe source of selenium for all animal species/categories when used up to the total maximum authorised selenium content in complete feed. In the absence of data, it would be prudent to treat the additive as an irritant to the skin and eyes, as a dermal and respiratory sensitiser and as an inhalation toxicant.
