The decrease in bee colony populations has been associated with various factors, including bacterial diseases. In response, the use of veterinary drugs for prevention or treatment in beekeeping is common, but this practice can result in drug accumulation in honey and other bee products. Consuming contaminated honey may lead to negative health effects, such as allergic reactions, hypersensitivity, carcinogenicity, reproductive issues, and teratogenicity.
This is why it is essential to maintain high levels of analytical performance for the honey matrix as well. To do so, as every year, we propose several interlaboratory circuits for the detection of Veterinary Drug Residues in honey. Among them, in 2025 returns:
PT for NITROIMIDAZOLES in HONEY
code H5508 – Round of November 2025
- Deadline for online orders: October 3rd 2025
- Shipping date: November 17th 2025
- Test Material: 30g of honey for confirmatory methods participation or 15g for screening methods participation (in case the provided volume is not enough, it is possible to order additional material at a reduced price)
- Molecules under study: Dimetridazole, metronidazole, Ipronidazole, Ronidazole,2-HydroxyDimetridazole (HMMNI), 2-Hydroxy metronidazole, 2-Hydroxy Ipronidazole. The Test Material may contain one or more of the molecules under study. It is not mandatory to search for all the analytes under study, you will receive the evaluation only for the molecules actually searched.
- Indicative concentrations: <15 ppb
- The price is only 362,00€ for confirmatory methods and 324,00€ for screening methods
Other matrices proposed in 2025 for Nitroimidazoles PTs are muscle (M5304) and egg (E5305).
OUR STRENGHTS FOR THESE PTs
- Separate evaluation data for screening and confirmatory methods, with the assigned value deriving only from quantitative confirmatory results. This feature of our PTs respects the requirement of UNI CEI EN ISO/IEC 17043:2010 to use fit-for-purpose methods of evaluation, makes the assigned value more reliable and the assessment more valid. Even if you are using a screening method, the PT simulates what you would do in the routine (comparing your results with confirmatory ones). The semi-quantitative (< or >) and qualitative screening results receive evaluations provided with dedicated criteria. The quantitative screening and confirmatory results are evaluated through z-score.
- Possibility to submit 2 sets of results and evaluate them in the Final Report, thus, with one subscription, 2 laboratory technicians, or 2 different methodologies.
- Information about False Positives is provided in the Final Report.
