National Reference Laboratories (NRLs)
The role of National Reference Laboratories (NRLs) and details of the UK and Northern Ireland (NI) NRLs for food and feed testing
NRLs are specialist laboratories responsible for maintaining standards for the routine testing of feed, food and animal health. They provide advice and support on methods for official control testing, ensuring the delivery of risk-based and proportionate food enforcement to protect consumers.
Food Standards Agency (FSA) has a legal obligation to designate NRLs for food and feed. FSA and Food Standards Scotland (FSS) designated food and feed NRLs for UK. FSA designated food and feed NRLs providing specific EU requirements for Northern Ireland.
Defra has a legal obligation to designate NRLs for animal health and live animals in Great Britain (GB). This role is undertaken by DAERA (Opens in a new window) for Northern Ireland (NI).
In GB, NRLs are designated under the Official Control Regulation (EU) 2017/625 for Official Feed and Food Controls (Opens in a new window), as amended and retained in UK legislation under Statutory Instrument 2020/1481 (Opens in a new window).
