1.
The L-lysine content shall be indicated on the labelling of the additive.
2.
L-lysine sulphate may be placed on the market and used as an additive consisting of a preparation.
3.
For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address potential risks by inhalation. Where those risks cannot be eliminated or reduced to a minimum level by such procedures and measures, the additive and premixtures shall be used with personal protective equipment, including breathing protection.
