The anthelmintics are substances which use is allowed to expel parasitic worms and other internal parasites from the infected animal. The Commission Regulation (EU) No 37/2010 establishes classification and maximum residue limits of pharmacologically active substances in foodstuffs of animal origin. Among these they are also defined the MRL for allowed substances, such as anthelmintics.

Our programme in 2025 will offer a PT for the research of anthelmintics in bovine muscle. Here below you can find details about our proposal for 2025. Moreover in april 2026 our PT for anthemintics in sheep liver is coming back.

OUR STRENGTHS FOR THESE PTS

• Separate evaluation of results for screening and confirmation methods, with the assigned value derived only from the quantitative confirmation results. This feature of our PTs fulfils the requirement of UNI CEI EN ISO/IEC 17043:2010 to use evaluation methods that are fit for purpose, thus making the assigned value more reliable and the evaluation more valid.
• Even if you are evaluating a screening method, PT simulates what you would do in your routine (comparing your results with confirmatory results). Semi-quantitative (< or >) and qualitative results from screening methods are evaluated with dedicated criteria. Quantitative screening and confirmation results are evaluated with z-scores.
• Even more reliable assigned value thanks to the high stability of our Test Materials, which are supplied as lyophilized (to be analysed after reconstitution) so that their stability is guaranteed even during long transports. In this way, every participant, regardless of their country of origin, can be sure to receive the sample in exactly the same condition as the other participants. After reconstitution, the material is as in your routine!
• Possibility to submit 2 results: with one purchased participation you will receive in the Final Report the evaluation for 2 laboratory technicians or 2 analytical techniques.
• Where participation involves sending 2 different Test Materials, (they may both be contaminated or one of them may be blank), in PT as in routine, the laboratory technicians do not know whether they are analysing a contaminated or a blank material. By providing 2 different Test Materials, the laboratory can then be assessed either for possible False Positives or for how the analytical method responds to different concentration levels.
• The information of False Positives will be present in the Final Report.
