Test Description

Animal products for human consumption are tightly legislated and closely monitored for compliance. Veterinary medicines used in animals are likely to have a pharmacological effect in humans. Hence, for many veterinary medicines, there are extremely low maximum residue limits or even no MRL (i.e. any detection is non-compliant). The Fapas quality control materials are produced in keeping with EU MRLs or minimum required performance limit (MRPL) where MRLs are not set. The result reporting requirements are also in keeping with quality control guidelines laid out in EC/657/2002. Fapas veterinary medicine quality control materials include incurred residues as well as fortified animal products. The quality control materials are grouped in analytical chemical class/matrix combinations and combine identification and quantification. The proficiency tests are suitable for all methods, including screening methods (for the detection of total amount of that chemical class).

Within this quality control material Malachite green, including leuco-MG and total MG can be evaluated.

It is important to highlight any high levels of veterinary medicine residues within foodstuffs to avoid passing on their effects to unsuspecting consumers. Your effective testing ability is key to protecting consumers from these potentially harmful chemicals. As such it is imperative to ensure high quality testing is undertaken across a range of testing environments and materials. Fapas quality control materials can be used to track your progress between proficiency tests as well as standardise your testing processes.

Quality control materials from Fapas can be used as part of staff training and instrumentation verification activities, from which to mitigate any risk of bias within your test results. This can give credible, repeatable results to offer to your customers.
