A dynamic panel to cover high-risk matrices and ensure global compliance
Despite the strict bans of Regulation (EU) 37/2010, nitroimidazoles (such as metronidazole and ronidazole) remain one of the most persistent challenges for food safety. EFSA reports and RASFF notifications confirm that these substances are detected every year in critical matrices like honey, aquaculture products, and poultry, often due to illegal treatments.
However, the risk is not limited to these sectors: analytical pressure is high across the entire livestock supply chain. For this reason, the ability to accurately detect these residues is a mandatory requirement for laboratories operating on an international scale.
A dynamic offer for real needs
The nitroimidazole panel offered by Test Veritas is designed to be broad and flexible. The matrices proposed in our Progetto Trieste programme change every year to meet the real needs of laboratories and respond to market trends. Over the years, our circuits rotate between eggs, milk, muscle, honey, and serum, allowing participants to test their competence on a complete range of products.
For 2026, our focus is on the bovine supply chain with three dedicated Proficiency Tests in the Round of May:
NItroimidazoles in bovine muscle (code M6304)
Molecules under study: dimetridazole – metronidazole – ipronidazole – ronidazole – 2-Hydroxy
Dimetridazole (HMMNI) – 2-Hydroxy Metronidazole – 2-Hydroxy Ipronidazole
Indicative concentrations: < 30ppb
Nitroimidazoles in bovine milk (code MI6305)
Molecules under study: dimetridazole – metronidazole – ipronidazole – ronidazole – 2-Hydroxy
Dimetridazole (HMMNI) – 2-Hydroxy Metronidazole – 2-Hydroxy Ipronidazole
Indicative concentrations: < 20ppb
Nitroimidazoles in bovine serum (SE6306)
Molecules under study: dimetridazole – metronidazole – ipronidazole – ronidazole – 2-Hydroxy
Dimetridazole (HMMNI) – 2-Hydroxy Metronidazole – 2-Hydroxy Ipronidazole
Indicative concentrations: < 10ppb
Participating in these PTs allows your laboratory to compare results with an international network of experts, ensuring reliable data ready for global markets.

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.
