1.
L-histidine monohydrochloride monohydrate may be placed on the market and used as an additive consisting of a preparation.
2.
The additive can be also used via water for drinking.
3.
The endotoxin content of the additive and its dusting potential shall ensure a maximal endotoxin exposure of 1 600 IU endotoxins/m 3 air ( 2 ) .
4.
For users of the additive and premixture, feed business operators shall establish operational procedures and organisational measures to address potential risks for the eyes and skin and by inhalation. Where those risks cannot be eliminated or reduced to a minimum by such procedures and measures, the additive and premixture shall be used with personal protective equipment.
