A patented cultivar of yeast (Saccharomyces cerevisiae CNCM I-3060) marketed as Sel-Plex® has been approved for use in animal fodder:
*	U.S. Food and Drug Administration approval for use as a supplement to feed for chickens, turkeys, swine, goats, sheep, horses, dogs, bison, and beef and dairy cows.
*	Organic Materials Review Institute approval for use as a feed supplement for all animal species.
*	As of 2006, the European Food Safety Authority's Scientific Panel on Additives and Products or Substances used in Animal Feed allows the use of Sel-Plex® in animal fodder for poultry, swine, and bovines, as the selenium is not significantly bio-accumulated by the human consumer. Only a small amount should be used when blending animal feeds, 10x the authorized maximum selenium intake causes a drop in production. Appropriate measures to minimize inhalation exposure to the product should be taken.
