Esta base de datos contiene la información más reciente sobre los niveles máximos de residuos en drogas veterinarias según lo recomendado por JECFA. Todas las monografías publicadas en la FAO sobre Alimentación y Nutrición, Papeles 41, son accesibles en formato electrónico. Estas monografías están sólo disponibles en inglés aunque algunas partes de la base de datos, como la página de preguntas y también una información básica se puede encontrar en árabe, chino, español, francés e inglés.

| El resumen de la evaluación |
In reaching its decision on MRLs for clenbuterol, the Committee tookthe following factors into account: - The ADI of 0-0.004 µg per kg of body weight per day, which is equivalent to a maximum ADI of 0.24 µg for a 60-kg person. - Muscle and liver are the target tissues. - The parent drug is the marker residue and is the only residue of public health concern. It accounts for 100% of the total residues in muscle, fat and milk (cows), 60% of the total residues in bovine liver and kidney, and 6% of the total residues in equine liver and kidney. Because the metabolites and bound residues are not of toxicological concern, they do not need to be taken into account in the calculation of the MRLs. - Analytical methods suitable for regulatory use are available. - The sponsor is not proposing to make the drug available for use in lactating cows. The Committee was aware that clenbuterol has been used illegally as a growth-enhancing agent, primarily in cattle. When used for this purpose, it must be administered up to the time of slaughter. Residue studies conducted under these conditions are available, and both these and results of regulatory monitoring indicate that residues are likely to be substantially in excess of the MRLs, particularly in liver. The Committee recommended that clenbuterol should not be used as a growth-enhancing agent. TRS 876 |
