Workers safety is key in premix and feed production locations. Some feed additives are recognized as occupational hazards for which inhalation represents the main route of exposure.

When there is a possibility that the occupational exposure limit (OEL) for a specific compound in air will be exceeded, due to high dusting potential of the additive, there is a serious toxicity risk. In this case, the dusting potential should be lowered to ensure workers safety.

This is also the case for selenium, which is toxic upon inhalation. The occupational exposure limit for selenium has been set at 0.2 mg selenium per m3 of air in the European Union legislation. Orffa considers it of great importance to ensure worker’s safety, and therefore developed a dust-free form of L-selenomethionine.
