UK food producers are leading the way in safety and quality by combining advanced screening technologies with rigorous laboratory validation. With growing concern over nitrates and nitrites in meat and dairy, producers rely on rapid testing tools like the RELAX/QUANTOFIX® system to deliver accurate, real-time results. Supported by certified reference materials (CRMs) and proficiency testing (PT) schemes, this robust approach ensures compliance, transparency, and consumer trust — reinforcing the UK’s global reputation for food safety excellence.
