Division 4.6 Studies on the quality of animal products where this is not the effect claimed

In order to demonstrate that the additive does not have a negative effect or other effect not requested on the organoleptic and nutritional (hygienic and technological if appropriate) characteristics of food deriving from animals fed with the additive (when this is not the effect desired), appropriate samples shall be taken during one of the efficacy trials. Two groups shall be observed: an unsupplemented group; and a group with the highest dosage proposed for the additive. The data shall allow statistical evaluation. Omission of these studies shall be adequately justified.
