Southern Microbiological Services Retains RSA Gold Approval for Pathogen Testing Excellence

We’re proud to announce that Southern Microbiological Services – A Tentamus Company has once again retained its RSA Gold approval, recognising our ongoing commitment to high-quality pathogen testing in the UK food industry.

This approval is part of a specialist audit scheme developed for Marks & Spencer (M&S) and Tesco, which assesses labs on the accuracy, reliability, and timeliness of their microbiological testing. Achieving and retaining RSA Gold status confirms SMS as a trusted partner in delivering data that supports critical food safety decisions.

Our team works hard to ensure our testing consistently meets the highest standards for both retailers and their suppliers, helping them stay compliant and confident in their food safety strategies.

Supporting Excellence Across the Tentamus Network

We’re equally delighted to share that our sister lab, One Scientific – A Tentamus Company, has also regained its RSA Gold status this year. It’s a fantastic result for both teams and a strong reflection of our shared mission to support retail microbiology and regulatory compliance across the UK.

A huge congratulations to everyone involved — your dedication, expertise, and consistency make this achievement possible.
