| Summary of the evaluation |
In recommending a suitable marker residue and common MRLs for cypermethrins used as veterinary drugs, the Committee consideredthe following factors: - alpha-cypermethrin consists of two of the four cis-isomers present in cypermethrin. - A group ADI for alpha-cypermethrin and cypermethrin of 0-0.02mg/kg bw, which is equivalent to 0-1200 mg per day for a 60 kg person, was established for the most toxicologically active substance (alpha-cypermethrin). - Using the common analytical methods for residue control, the eight isomers of cypermethrin cannot be resolved and a single, fused chromatographic peak is obtained. Therefore, residues reported represent the sum of all isomers. - After considering the request for a common set of recommendations for residues of cypermethrin and alpha-cypermethrin in cattle and sheep tissues and rounding, as appropriate, the Committee recommended the following MRLs, expressed as the total of cypermethrin residues: muscle, liver and kidney, 50 mg/kg and pid=63155; fat, 1000 mg/kg and pid=63155; and milk, 100 mg/kg. The recommended MRLs in muscle, liver and kidney were based on the limits of quantitation of the new methods, considering that the concentration of residues in both cattle and sheep tissues was less than or equal to 35 mg/kg. The MRLs for fat and cow's milk were based on residue depletion data. These MRLs replace those previously recommended. TRS 925 |
