Division 4.5 Efficacy requirements for additive categories and functional groups

For all additives intended to have an effect on animals, in vivo studies are requested.

For the categories of zootechnical additives and coccidiostats and histomonostats, efficacy shall be demonstrated by at least three long term efficacy studies. However, for some zootechnical additives and the other additive categories having an effect on animals, short term efficacy studies may be accepted if efficacy can be unequivocally demonstrated.

For other additive categories without a direct effect on animals at least one in vitro efficacy study shall be provided.
