Levels of advancement
II10 Residue testing The capability of the VS to
medicines (e.g. antimicrobials and hormones), chemicals, pesticides, radionuclides, metals, etc.
No residue testing programme for animal products exists in the country. Some residue testing programme is performed but only for selected animal products for export. A comprehensive residue testing programme is performed for all animal products for export and some for domestic use. A comprehensive residue testing programme is performed for all animal products for export and/or internal consumption. The residue testing programme is subject to routine quality assurance and regular evaluation.
[Note: This critical competency may in some countries be undertaken by an agency or agencies other than the VS.]
Results Strengths : The competencies to conduct residue testing exist within CVL, as it has the experience and trained personnel. Weaknesses : Residue testing is limited to those residues tested strictly on export abattoirs and in accordance with importing country requirements. Nevertheless, the majority of the animals consumed in Namibia are slaughtered at these export establishments.

Laboratory Equipment used to carry out residue testing at CVL:
1 X HPLC with UV and fluorescence detectors
1 X HPLC with Diode Array detector
1 X GC with Electron capture Detector (ECD) and Nitrogen Phosphate Detector ‐ (NPD) for pesticides (Organophosphates and Organochlorides)
1 X ELISA Reader for Clenbuterol, Chloramphenicol, Gestagens, Zeranol and ‐ Trenborone screening
Four Plate Inhibition Test (FPT) for antimicrobials testing
Priorities/Recommendations Short Term :
Medium / Long Term : CVL should undergo a systematic review (OIE gap analysis) in order to address the weaknesses
