One Scientific Regains RSA Gold Approval for Pathogen Testing Accuracy

We’re excited to announce that One Scientific – A Tentamus Company has proudly regained its RSA Gold approval, highlighting our lab’s strong performance in microbiological testing for UK retailers and suppliers.

The RSA Gold standard, developed as part of a dedicated audit scheme for Marks & Spencer (M&S) and Tesco, recognises labs that deliver accurate, reliable, and timely pathogen testing — essential for informed decisions in food safety and quality management.

This achievement reflects the expertise, focus, and resilience of our team in maintaining the highest standards across all areas of testing and compliance.

Shared Success Across the Tentamus Group

We also want to congratulate our sister lab, Southern Microbiological Services (SMS) – A Tentamus Company, on successfully retaining their RSA Gold approval. Both achievements highlight the strength of the Tentamus UK lab network and our shared commitment to helping retailers and suppliers meet the most rigorous standards in food safety and regulatory compliance.

Well done to everyone involved for their continued excellence!
