Campden BRI RSA Scheme for M&S and Tesco
For product safety M&S, Tesco and their Suppliers must have confidence in
action is taken based on reliable data.
The Campden BRI Retailer Supplementary Audit (RSA) Scheme was established with M&S and Tesco and
launched in 2019 to provide common supplementary audit scheme for both Retailers to recognise
Microbiology Laboratories that undertake pathogen tests on their own label products and related materials
Audits are specific to M&S/Tesco pathogen testing activities to verify if standard of service, quality
of work and reliability of results meets Retailer specific requirements and methods comply with
Retailer approved methods.
A performance related approach is used to appraise ability to deliver consistent, accurate, reliable,
defendable and timely pathogen results.
RSA Compliance status requires successful completion of an annual audit
and a performance level is
given based on audit findings.
Scope of RSA audits
Food, drink, components and environmental swabs where M&S or Tesco has set
microbiological criteria for one or more of the following pathogens:
- Salmonella spp;
- Listeria monocytogenes and Listeria spp;
- Campylobacter spp;
- E.coli O157/STEC
- Cronobacter spp
- Vibrio parahaemolyticus, Vibrio cholerae, Vibrio vulnificus
- Bacillus cereus
- Clostridium perfringens
- Coagulase positive Staphylococci
RSA Scopes of Compliance will cover only pathogens and methods actively
used to test M&S/Tesco materials that meet Retailer requirements. Extensions/modifications can be
made between audits or at annual audits to keep Scopes relevant to laboratories needs.
RSA Scheme documents
On registration with the RSA Scheme laboratories will be given access to:
- RSA Scheme Protocol - conditions for participation, audit process and validity of RSA Compliance
- Retailer Requirements for Microbiology Laboratories Performing Pathogen Tests - activities covered by
audits and requirements laboratories must meet.
- Retailer Approved Methods for Pathogens - approved methods that must be used for M&S and Tesco
Retailer requirements for laboratories
Retailer requirements for laboratory operations, management, delivery of
work, and result reporting include enhancements to requirements in ISO/IEC 17025 and specific
retailer requirements not covered by ISO/IEC 17025 based assessments including areas where concerns could impact on results.
No RSA requirements conflict with or contravene ISO/IEC 17025:2017.
Retailer approved methods
To promote reliable results and strengthen due diligence in relation to
food safety only methods of recognised status, fully supported by robust validation and compatible
with requirements in relevant legislation for pathogens are approved for use by M&S and Tesco.
Use of RSA Retailer approved methods only applies to pathogen testing
performed on M&S/Tesco materials. There is no requirement for laboratories to use these methods for
other client work.
Requests for approval to use an alternative to an RSA Retailer approved
method can be considered by the RSA Scheme Method Review Coordinator and Retailers. If approved the
method will be added to the list of RSA Retailer approved methods. (This process is outlined in the RSA Protocol)
M&S/Tesco supplier responsibilities
Effective communication and provision of information between M&S/Tesco
Suppliers and laboratories is essential to ensure retailer requirements and responsibilities for
sample submission, testing and reporting are clearly understood, agreed by both parties and followed.
Co-operation is necessary between Suppliers and laboratories for
laboratories to demonstrate compliance with relevant Retailer requirements.
General guidance notes for Supplier input/responsibilities
will be available soon.
RSA Compliant laboratories
RSA Compliant laboratories and RSA status
Eligibility to join RSA scheme
Any microbiology laboratory that satisfies the following can register to be
an RSA Compliant laboratory:
- Must have an M&S/Tesco Supplier as customer (or can demonstrate a Suppliers commitment as a new customer
to use the laboratory).
- Must test M&S/Tesco food, drink, components and/or environmental swabs for 1 or more of the following
pathogens: Listeria, Salmonella, Campylobacter, E.coli O1576/STEC, Cronobacter, Vibrio,
Staphylococcus aureus, Bacillus cereus, and Clostridium perfringens.
- Must be accredited to an ISO17025 based standard by a recognised Accreditation Body (e.g. UKAS, INAB or
International Equivalent, CLAS) for the pathogen testing activities in question.
Application for RSA compliance
New applications: Please complete and return the
RSA Scheme application form
Please note the requirements in this form relating to Data Processing and
Disclosure of Information on this RSA webpage and to M&S/Tesco concerning participation in the RSA
Scheme and your laboratory’s acceptance of these.
An audit approx. 3 months after receipt of application will normally be offered. (To allow review of RSA requirements and methods, and make changes to comply). Thereafter subsequent audits will be in the due month.
If needed, Provisional RSA Compliance can be considered upon to ensure Retailer work is in place for the
audit. (Applicable only to new applications – see RSA Protocol for details)
Requests for Extensions/Modifications to RSA Scopes In between Audits:
