Résumé de l'évaluation The following factors were taken into account in estimating the MRLs:
- The ADI
- The parent drug is a suitable marker residue and accounts for 2.4% of the total residues.
- All of the residues in muscle and fat are free residues and are equivalent to parent drug.
- Of the residues in liver, 50% are present in the bound fraction, and 15% of the bound residues are bioavailable.
- The residues in kidney are qualitatively similar to those in liver.
- It is assumed that all bioavailable residues in liver and kidney are equivalent to parent drug.
- The residues are similar in cattle, sheep and pigs.
Because residues at 1-day withdrawal in yolks of eggs laid by hens given the recommended dose were approximately 800 µg/kg, the Committee considered that levamisole should not be used in laying hens and did therefore not reconmend an MRL for eggs. No new data were submitted by the sponsors to support the re-evaluation of levamisole residues in milk. The Committee therefore withdrew the temporary MRL for milk, that was allocated at its thirty-sixth meeting. The sponsors recommend that levamisole should not be used in lactating cows.
If the recommended values are used for the MRLs and account is taken of the factors mentioned above, the theoretical maximum intake of residues of parent drug and its equivalents is 397 µg per day: of which only 14 µg is parent drug.
In view of the inherent variability involved in estimating total levamisole-equivalent residues based on levamisole as the marker residue and the fact that only a small proportion of the total residues is used to estimate the total levamisole equivalents, the Committee considered this value to be approximately the same as the ADI.
