WOAH reference laboratory

APHA is also the World Organisation for Animal Health (WOAH) reference laboratory for bovine spongiform encephalopathy (BSE) and scrapie.

We have specialist experience in TSE diagnosis, surveillance and consultancy. Also, we have played a key role in confirming BSE index cases in several countries. 

National reference laboratory (NRL) remit

The NRL provides containment facilities and expert staff to confirm cases of animal TSE and identify the specific type or strain of disease.

It monitors the diagnostic methods used across the UK TSE laboratory network, coordinates diagnostic standards and stores and maintains representative samples from confirmed cases.

The UK TSE laboratory network carries out TSE surveillance in the UK through a group of private and public laboratories:

  • Eurofins, Risley: commercial partner undertaking TSE rapid-testing of eligible animals in Great Britain

  • AFBI, Stormont: TSE rapid-testing in Northern Ireland

  • APHA Weybridge, Histopathology Team: Histology, Immunohistochemistry (IHC)

  • APHA Weybridge, Molecular Pathology team: Rapid-testing, Western Blotting

  • APHA Weybridge, Central Unit for Sequencing and PCR (CUSP): Genotyping

  • APHA Weybridge, Animal Protein in Feed NRL: Microscopic Analysis Test (MAT), Feed PCR (email: feedanalysisweybridge@apha.gov.uk)

EU reference laboratory (EURL) for TSEs

Between 2001 and 2018, APHA was designated by the European Commission as the EU reference laboratory (EURL) for TSEs.

From 1 January 2019, responsibility for the EURL function for TSEs transferred to a consortium including:

  • Istituto Zooprofilattico Sperimentale del Piemonte, Liguria e Valle d'Aosta (IZSTO), Turin, Italy

  • Istituto Superiore di Sanità, Department of Food Safety, Nutrition and Veterinary Public Health (SANV), Rome, Italy

The transfer took place as part of the UK's withdrawal from the European Union.
