Do you have the PRP technical standard scheme 22001-2? The easiest thing to do would be to make an audit checklist
for instance,
in the ISO 22001-2 PRP technical standard, you have the following PRPs
4 Construction and layout of buildings..................................................................................................4
5 Layout of premises and workspace ....................................................................................................5
6 Utilities – air, water, energy..................................................................................................................6
7 Waste disposal ......................................................................................................................................8
8 Equipment suitability, cleaning and maintenance.............................................................................9
9 Management of purchased materials ................................................................................................10
10 Measures for prevention of cross contamination............................................................................11
11 Cleaning and sanitizing ......................................................................................................................12
12 Pest control..........................................................................................................................................13
13 Personnel hygiene and employee facilities......................................................................................14
14 Rework..................................................................................................................................................16
15 Product recall procedures..................................................................................................................17
16 Warehousing........................................................................................................................................17
17 Product information/consumer awareness ......................................................................................18
18 Food defence, biovigilance and bioterrorism...................................................................................18
you would need to do this for all 18, but using as an example PRP 18 Food Defense, biovigilance and bioterrorism, I would have a checklist (made against the PRP 18 requirements) like below
- Have all sensitive areas been identified and secured or otherwise access controlled using locks, badge access, or other measures to restrict access to authorized personnel only?
- Have acts of sabotage, vandalism, and terrorism that could affect sensitive processes or products been assessed and mitigated by protective controls?
you would answer those questions as such (compliant, not compliant (e.g., new sensitive area identified and not access restricted, etc.) And at the end of the entire verification audit you will probably want a summary of the results (e.g. what was found, what PRPs needs to be improved, etc.)
I am guessing you are doing something like this anyway since ISO 22000 basically requires the food safety team to review and verify PRPs (see section 8.2 in ISO 22000:2018)
