Directive 2009/9/EC lays down detailed scientific and technical requirements for the testing of veterinary medicinal products to assess their quality, safety and efficacy. For the authorisation procedure for veterinary medicinal products to function properly, it is crucial that Member States apply the up-to-date requirements. Otherwise the approval and market entry of new products may be delayed.
