(70)In other cases, the rules falling within the scope of this Regulation provide that the placing on the market or the movement of certain animals or goods are to be accompanied by an official label, official mark or other official attestation issued by the operators under the official supervision of the competent authorities or by the competent authorities themselves. Official attestations include, for example, plant passports, organic logos and identification marks, where these are required by Union legislation, and marks of protected designations of origin, protected geographical indications or traditional specialities guaranteed. It is appropriate to lay down a minimum set of rules to ensure that also the issuance of official attestations is able to be performed in accordance with appropriate guarantees of reliability.
