EURL methods & forms

EURL methods

The responsibilities and tasks of European Union Reference Laboratories (EURLs) and of National Reference Laboratories (NRLs) are listed in the Regulation (EU) 2017/625. Additional responsibilities and tasks for the EURL for Bee Health are listed in the Commission Regulation (EU) No 415/2013. The methods used within the European NRLs should follow the rules listed in the Commission Delegated Regulation (EU) 2020/689. In this last regulation, a cascade of methods for sampling, analyses, tests and diagnosis is described in Article 6. Hence, official laboratories and NRLs have to use details and guidance made available on the EURL websites and complying with the Regulation (UE) 2016/429. In the absence of the above, internationally recognised rules or protocols (i.e. OIE’s Terrestrial Manual) shall be followed. In the absence of the above, nationally recognised rules shall be followed or, if no such rules exist, relevant methods developed or recommended by NRLs shall be used. In the absence of the above, and when analyses, tests or diagnoses are urgently needed, methods other than those above-mentioned can be used until the validation of an appropriate method in accordance with internationally accepted scientific protocols.

Please find below the diagnostic methods related to bee diseases pursuant to Article 6 of the Commission Delegated Regulation (EU) 2020/689.
