Czech National Reference Laboratory for Animal Proteins

Animal protein detection in feeds has completed ten years of successful operation on the international level. Precisely ten years ago, the laboratory engaged in this activity became the National Reference Laboratory for Animal Proteins in Feeds (NRL-AP). The laboratory is operated within the framework of the Feeds Department of the Central Institute for Supervising and Testing in Agriculture. For the first time, it was accredited in 2006 for the detection of animal proteins in feeds using a microscopic method, the only recognized reference method at that time within the European Union (EU).


During 2009 and 2010, the laboratory developed active efforts to become engaged in the development of the RT-PCR (real-time polymerase chain reaction) method aimed at helping to specify the species and exact origin of contamination. Subsequently, the laboratory was equipped with the necessary systems and successfully established and accredited the RT-PCR methodology. The laboratory is charged of testing and inspecting feeds for any presence of animal proteins, and if a positive finding is determined, with specifying the form of contamination. The purpose is to ensure safety in terms of BSE/TSE spreading in ruminant animals.


The laboratory passes at least two qualification tests on a regular basis with the EU Reference Laboratory (EURL-AP) focused on the microscopic method and on the RT-PCR method. Since 2006, the laboratory has been evaluated as the second best laboratory in the qualification tests – the so-called “EURL-AP Proficiency Tests“ – among the 27 national reference laboratories of EU countries.
