Division 4.1.3.2 Studies concerning the safety of use of the additive for consumer

Metabolic and residue studies

These studies are not required if:

• the substance or its metabolites can be demonstrated to be excreted unchanged and essentially to be not absorbed; or

• the substance is absorbed in physiological form and physiological level of compound(s).

No metabolic studies are needed if the substance is naturally present in significant amounts in food or feedingstuffs or if the substance is a normal constituent of body fluids or tissues. However, in these cases, there is a requirement for residue studies which can be limited to a comparison of the levels in the tissues or products in an untreated group to the levels found in the group supplemented with the highest recommended dose.

In all other cases the whole of subsection 3.2.1 of Annex II applies.

Toxicological studies

Toxicological studies are not required if the substance is absorbed in the form of physiological compound(s).

For xenobiotic substances the whole of subsection 3.2.2 of Annex II applies.

For other substances, a case by case approach shall be used, taking into account the level and means of exposure, and any omission of data prescribed in this section must be fully justified.

Assessment of consumer safety

The whole of subsection 3.2.3 of Annex II applies for food producing animals.
