Thank you CMHeywood,
but when it comes, for example, to laboratory services there is no requirements for food safety. The samples are sent to a certified and approved laboratory.
Am I right ?
Which standard are you using? I think you're referencing BRC based on the wording, but the clause is actually 3.5.3 in Issue 7.
Under BRC, there are requirements for food safety. Per 18.104.22.168 "Where the company undertakes or subcontracts analyses which are critical to product safety or legality, the laboratory or subcontractors shall have gained recognized laboratory accreditation or operate in accordance with the requirements and principles of ISO. Documented justification shall be available where accredited methods are not undertaken."
Interestingly enough, the analyses you choose to perform that are critical to product safety or legality must also be accredited, unless you or the lab can justify why the method isn't accredited. The laboratory's accreditation sheet must show that they are certified ISO 17025 for the critical analysis you need. For example, if you are testing for Listeria or Salmonella, you need to make sure the laboratory is certified ISO 17025 for those tests. An agreement should be made between you and the lab that they remain certified for your critical testing, or provide the aforementioned justification.
