Revised Guidance Document on Method Extension
The EURL guidance document on method extension is now available as version 2.0. A table highlighting the required samples for the reduced validation scheme in accordance with the conventional validation approach has been updated. The EURLs hope that this will facilitate the implementation of the approach and encourage the submission of additional feedback in order to improve the overall quality of the guidance documents.
Revised contaminant legislation
In a field adjacent to the control of residues of veterinary medicinal products in foods, Commission Regulation (EU) 2023/915 has been adopted recently and will enter into force from 25th May, 2023. This Commission Regulation repeals Regulation (EC) No 1881/2006 and deals with maximum levels of certain contaminants in food. The document may be retrieved from EUR-Lex.
COCC0423: Sample shipment
The samples for the proficiency test COCC0423were 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. Best of success for your analyses!
Revised EURL guidance document on the quality control during routine analysis
The EURL guidance document on the quality control during routine analysis (ongoing performance verification) is now available as version 1.2. Taking into account the feedback received from the NRLs, a section on the selection of representative analytes on which to monitor the method performance has been introduced. The EURLs hope that this information will be helpful to the laboratories active in the field of the analysis of residues of veterinary medicinal products. The provision of constructive feedback for example during the EURL workshops or by e-mail is encouraged and helps to improve the practicality of the guidance documents.
COCC0423: Registration now open
Starting from today until 31 March, 2023 eligible laboratories are asked to register for the upcoming proficiency test on the determination of coccidiostats in liver. More information is available here.
