تتضمّن قاعدة البيانات أحدث المعلومات عن الحدود القصوى لمخلفات العقاقير البيطرية بناء على توصية لجنة الخبراء المشتركة بين منظمة الأغذية والزراعة ومنظمة الصحة العالمية والمعنية بالمواد المضافة إلى الأغذية. ويمكن الإطلاع على جميع الدراسات المفصّلة لمواضيع معيّنة الواردة في النسخة الإلكترونية لورقة منظمة الأغذية والزراعة الخاصة بالأغذية والتغذية رقم 41. لكنها متوافرة باللغة الإنكليزية فقط رغم توافر بعض الأجزاء في قاعدة البيانات وصفحة البحث والمعلومات الأساسية باللغات الإنكليزية والفرنسية والأسبانية والعربية والصينية.

The Committee noted that on the basis of an MRL of 15mg/kg fordoramectin in whole milk in cattle, the milk discard times would be approximately 240 h according to the studies using the pour-on treatment. Milk discard times would be approximately 480 h after treatment using the dose formulated for injection. The Committee noted that the discard time necessary to accommodate the recommended MRL in milk was unlikely to be consistent with good veterinary practice. |
| ملخص عن التقييم |
In recommending MRLs for doramectin in milk, the Committee considered the following factors: - The ADI for doramectin was 0-1 mg/kg bw, equivalent to an intake of up to 60 mg per day for a 60 kg person - Based on MRLs for tissues in cattle and pigs, and the theoretical maximum daily intake of residues in tissue of 33 mg per day, approximately 27mg per day are available for milk. - Based on its limited metabolism and the known large partitioning ratio for residues between milk fat and aqueous milk, the Committee considered that the ratio for marker residue to total residue for doramectin in milk would be equivalent to the ratio of doramectin residues in fat (0.80). - The residue studies provided used a pour-on formulation at 0.58 mg/kg bw and the injectable formulation at 0.23 mg/kg, somewhat in excess of the recommended doses of 0.5mg/kg bw and 0.2 mg/kg bw, respectively. - The marker residue is doramectin. - A suitable analytical method is available for determining residuesin milk. Based on the factors noted above, the Committee considered recommending an MRL on the basis of the available portion of doramectin residues permitted by the ADI. The Committee recommended an MRL of 15mg/kg, determined as doramectin. Taking into account the marker residue to total residue ratio in fat (0.8) and 1.5 kg of milk in the model food diet, this would be equivalent to 28mg. Total residues of doramectin for muscle, liver, kidney and fat tissues and cow's milk, estimated from the model food diet, would be 61mg/kg. TRS 925 |
