The Residue Laboratory (Analytical Services) is the National Reference Laboratory for Antibiotics, Pesticides and Veterinary Drug residues in feed and animal products for over 15 years. Currently, the laboratory delivers the South African National Residue Control Plan (NRCP) under Council Directives 96/23/EC and the National Residue Monitoring Plan, which involves testing approximately 7000 samples per annum.
The laboratory has a standing vigorous system that ensures "chain of custody" and all analytical methods used for this purpose have been validated and are accredited to ISO 170205 (SANAS) standard (Technique/Matrix/Analyte dependant).

| | Training
The residue laboratory provides training for local students (Postgraduate and experiential) on various topics in food and feed safety analysis. The laboratory also provides external training for researchers, technicians and quality control officers from various countries in the African continent under the International Atomic Energy Agency (IAEA) coordinated research project.
The laboratory encourages knowledge and skills transfer through scientific exchange programme for postgraduate students, postdoctoral fellows and experienced researchers. |
