The Challenge of Producing RM with Veterinary Drug Residues

Alfredo M. Montes Ninio, President, Microbioticos, Sao Paulo, Brazil (

In order to produce biological reference material from veterinary drugs residues, a pure drug is needed. This drug ought to be characterized by a known supplier, which should have all certain physical and chemical properties. Afterwards, the drug must be administered to an animal, or group of animals, that have previously performed clinical studies to verify their healthy physiologically conditions. Once the drug is administered, the animal must be sacrificed. As the animal’s tissue, which will produce reference materials, must be extracted for analysis. This will be done throughout precise methods, such as mass spectrometry, to verify its residue amount.

Thereafter, the process by which the reference material will be preserved should be determined. As well as its form of packaging. The preservation process recommended today is lyophilisation. One should also make artificial aging experiments to establish which will be the span of this reference material. These will be performed throughout temperature and humidity test to establish how long they last and knowing the stability of the molecule of course, and there are also some that are metabolized continuously in the material. Checks must also be made periodically until the stock that is to be distributed is exhausted.

A question one must ask, is whether it is worth doing all this process. Since the stability of veterinary drugs residues in animal tissue is highly relative. Further, reference materials, in many cases, have become popular for accreditation, rather than performing permanent analyses controls. This is due to the fact that, it is easier for auditors to evaluate the quality of the methods. Nevertheless, today one should mainly explore statistical reference materials. Which consists of using Big Data as a source of information of the resulted data from accumulated signals in the chromatograms, etc.
