Guidance on studies concerning the safety of use of the additive for users/workers

This document provides guidance on how to conduct studies concerning safety for the user/workers. Users/workers are defined as the persons who may be exposed to the additive while handling it, when incorporating it into premixtures or feedingstuffs or using a feedingstuff supplemented with the additive. An assessment of risk to users/workers should be included based on toxicological studies relevant to the nature of the additive. Experience in the manufacturing plant may be an important source of information in evaluating the risks to workers from exposure to the additive itself by both airborne and topical routes.
