EFSA: Selemax from Biorigin approved in Europe

The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) has approved the safety and efficacy of Selemax (Biorigin, Brazil), a source of selenium in the form of organic compounds produced by a selenium-enriched yeast when used as a nutritional additive for all animal species.

Selemax consists of selenium-containing inactivated yeasts based on Saccharomyces cerevisiae enriched during the fermentation process with selenium. The additive is intended to be marketed in two forms, Selemax 1000 and Selemax 2000, which differ only in the final selenium concentration.

A tolerance study in chickens for fattening, one of the most sensitive species, at 6-fold the maximum authorised content in complete feed demonstrated that Selemax is safe when supplemented up to the maximum authorised content of selenium in complete feed.

Provided that the maximum authorised selenium content in complete feed is not exceeded, the use of Selemax as selenium source is considered to be safe for all animal species.

To ensure consumer safety from consumption of tissues and products of animals treated with Selemax, the FEEDAP Panel maximises feed inclusion of Selemax, (and other selenised yeasts) to 0.2 mg Se/kg complete feed.

Based on the response of liver glutathione peroxidase activity and the selenium level in plasma and liver of piglets to dietary supplementation of selenium from Selemax, the Panel considers this additive an effective source of selenium for all species. Selemax does not modify the quality of meat as measured by physical parameters.
