Dear Vincenso,
This is a sort of GAP Analysis question I think ?
Well, basically, the auditor requires to see compliance with the BRC standard.
I presume there is no declared requirement for specific presentation style, eg combined manuals, in the standard. If not, it’s up to you. From memory, a similar query also frequently appears here from people starting ISO22000. Subsequently, some seem to combine, some not, their choice I suppose. IMO, the primary requirement is that any manual (s) involved will hv to
adequately address the various paragraphs of the BRC standard with respect to the site involved (yr current manuals may well
not do so [??] which may be most simply resoved through a dedicated combined version depending on yr writing skills). Normally IMEX the auditors like to find a “nice” aligned-to-the-standard documentation style but that is another aspect and, after all, you are paying them sooooo. ( eg, I hv found that most auditors seem to expect to see decision-tree
CCP analyses which I do not use so questions invariably occur, although the end result is similar).
A similar answer to yr other query on QEHS (which I had to google) but surely much easier to issue an appropriate “BRC matched” policy perhaps, unless you already hv the other format stuck up all over the facility. (Assuming that you can properly demonstrate support for the "BRC, FS" policy of course.)
Some people invest in a preliminary BRC audit such that they can ask questions like this in advance, maybe even for free. (I noted yr source location

).
Any direct users of BRC v5 please comment (and amend if necessary).
