In correspondence with the EURL BVL workplan for the current work period, the EURL BVL will offer a webinar focusing on two topics for all interested NRLs on Thursday, 15 December 2022:
15.12.2022, 9:30 – 10:30 a.m. CET: Almanac data base
This webinar deals with the method data collection. Most NRLs have meanwhile entered their method performance data into the Almanac data base. In the webinar, we will give an overview of the results obtained so far, show substance-group-specific evaluations and will answer open questions on data entry and the use of the data base.
15.12.2022, 11:00 – 12:00 a.m. CET: Laboratory-comprehensive validation study – multi-analytes/multi-substance-groups in milk
In the past working periods several laboratory-comprehensive validation studies with participants from many NRLs were organised and successfully finalised. The benefits from participation in such studies are :
- Provision of a detailed method description, practical training (if required), provision of standard substances
- Provision of a validation plan (and a time frame to be followed)
- Provision of an individual and a laboratory-comprehensive validation report
- Complete method validated in accordance with CIR (EU 2021/808) – if participation was successful
The participating laboratories should have the respective resources to carry out the analysis according to the method description and the validation plan in the provided time frame.
Our new validation study will mainly cover substance groups B2e, A6 (nitroimidazoles, CAP), B1 and A3 (corticosteroids) in the matrix milk. The method was devised as a confirmatory method, but can also be used for screening. The detection can be carried out on either LC/MSMS instruments or HRMS instruments. The practical part of the validation study will start in 2023. It would be very much appreciated if you could consider to participate in this study, given the respective resources are available in your lab and there is need for such a method.
During the webinar the details of the method including the list of analytes will be provided. Furthermore, a validation plan and a timetable for the validation study will be presented (implementation of the method, training (if applicable), test run, validation runs, reporting, final evaluation). In the follow-up to the webinar, we will hold a question-and-answer-session for your questions with regard to a possible participation in the study.
If you wish to participate in one – or both – parts of the webinar, please fill in and submit your registration no later than 9 December 2022 (details have been provided to NRLs by e-mail).
The samples for the proficiency test NIIM1122 were shipped today. All participants are asked to fill out the sample receipt form. The password has been provided via e-mail. Further information on the PT is available here.
The Commission Implementing Regulation 2021/808 which lays down requirements for the performance of methods for the analysis of veterinary drug residues has entered into force on 10 June, 2021. In addition to this document, COM asked the EURLs to provide guidance to support the implementation of the new CIR. For this purpose the EURLs have – with the NRL’s support – published several guidance documents outlining their interpretation of CIR 2021/808. These documents are meant as a support for all laboratories but they are not seen as mandatory to follow and other approaches are possible if comparable results are achieved. Still, they aim at a harmonised interpretation of CIR 2021/808 and therefore greatly benefit from the NRL’s contributions. In order to address several laboratories’ request for additional guidance on the application of the standard addition approach respecting the provisions of CIR 2021/808, a working group was formed. The working group and the EURLs are pleased to present the first draft of the Guidance Document on Standard Addition and would now like to initiate the commenting process.
As always, all NRLs are asked to provide their feedback using an online form provided by e-mail by 22 November 2022. As a final step all comments will be reviewed and the draft will be amended.
Due to transitory measures, several annexes to CD 96/23/EC have remained in force even after publication of the revised official control regulation Reg. (EU) 2017/625. The provision given therein have now been updated and published in new regulations. Commission Delegated Regulation (EU) 2022/1644 of 7 July 2022 contains information on substance groups and commodity groups to be controlled, as well as criteria for sampling strategies. Commission Implementing Regulation (EU) 2022/1646 of 23 September 2022 gives detailed information on the preparation of the multi-annual national control plans (MANCP). Both newly adopted regulations will apply from 15 December 2022.
Starting from today until 24 October 2022 eligible laboratories are asked to register for the upcoming proficiency test on the determination of nitroimidazoles in porcine muscle. More information is available here.
Due to the postponement of the sample shipments, the deadline for result submission has been adjusted. Please submit your results by 07 October 2022. Further information is available here.
Due to further issues with the logistic services provider, the BETA0622 sample shipment for international participants had to be postponed once more. A new shipping attempt is planned for 19th July, 2022. The deadline will be adjusted accordingly and will be communicated in due time.
The EURLs are pleased to announce that the guidance document on minimum method performance requirements (MMPRs) has been updated and version 2.0 is now available. The changes with regard to the previous version pertain to residue definitions and matrix changes, as well as clarifications regarding the MMPRs to be considered for authorised pharmacologically active substances, for which no MRL has been set for a specific matrix or species. In addition, the MMPR document has been endorsed by the Standing Committee on Plants, Animals, Food and Feed, which is certainly a significant contribution to harmonised residue control throughout the European Union.
The EURL Berlin will arrange shipment of the sample sets for the proficiency test BETA0622: Beta-agonists in bovine urine for Tuesday, 05th July 2022. The deadline for result submission will be changed to 23rd September 2022.
