Test Description

Sulfonamides make up a significant proportion of veterinary medicines, and as such effectiveness of detection and quantification is key to promote safe foodstuffs for consumption. With a non-targeted detection method needed, key challenges of laboratory testing abilities can be made using proficiency testing to effectively evaluate your capabilities in a simulated environment.

Fish is a highly consumed form of protein globally. This high consumption can leave the supply chain at risk from poor farming practices, which can affect large amounts of consumers globally, owing to the global fish supply chain.

Veterinary medicines used in animals have a wide range of effects in humans. Hence, many veterinary medicines have extremely low maximum residue limits (MRLs) or even no limit, where any detection is classed as non-compliant. The Fapas proficiency testing (PT) 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 PT materials include incurred residues as well as fortified animal products and by combining identification and quantification, your lab can be challenged to simulate real routine testing. The PTs are suitable for all methods, including screening methods (for the detection of the total amount of that chemical class).

Quality control materials are invaluable in maintaining the high-quality testing required to maintain the high testing standards expected by both your customers and regulators. Fapas quality control materials make use of real food matrices, which can allow you to highlight areas of bias within your current routine analysis arrangement. This could be in the form of staff training measures, or instrumentation verification activities.
