S.L. 449.19 ст. 7How to establish MRL.

(1) In establishing maximum residue limits for residues of veterinary medicinal products used in foodstuffs of animal origin, it is necessary to specify the animal species in which such residues may be present, the levels which may be present in each of the relevant meat tissues obtained from the treated animal (target tissue), and the nature of the residue which is relevant for the monitoring of residues (marker residue).

(2) In order to control for residues, maximum residue limits shall be established for the target tissue of liver or kidney; however, since liver and kidney are frequently removed from the carcasses marketed in the international trade, maximum residue limits should therefore also always be established for muscle or fat tissues.

(3) In the case of veterinary medicinal products intended to be used for laying birds, lactating animals or honey bees, maximum residue limits shall also be established for eggs, milk, or honey.
