Is this decision tree confirmed by Codex? Should I update our documents to this?
Codex-related queries may not be relevant to iso22000. Note also that Codex (2020) no longer included it's long utilised tree.
I think Tony/Codex's proposed trees are slightly amplified (easier to understand/use) versions of the famous Campden Decision tree which was published many, many years ago in UK. For example -
FSA (Campden) HACCP Decision Tree.pdf 76.26KB
(Codex does not restrict the use of alternative trees or Procedures.)
afaik, Iso22000 is not governed by Codex Rules although some overlaps may exist..
I was unable to see an option for sorting of raw material to be a PRP via iso22002-1.
There is at least one crucial step in the hazard analysis of iso22000 -
Is the hazard identified actually a Significant hazard (SH) ? [ie See Post 2,(2)]
The procedure to determine a "significant hazard" is defined in para 18.104.22.168. Use of 22.214.171.124 obviously indicates that there is a significant (Physical) hazard at the sorting step. (This new ISO approach (modified from original version) is afaik contrary to some other previously published, Codex-based, haccp procedures and, I deduce, has been modified to add conformity with the, IMO, analogous and equally peculiar (to me) hazard logic requirements in FSMA's haccp system. (Extensively, previously, discussed on this Forum but not afaik leading to any final conclusion).
IMO a "conventional" haccp, L x S, hazard analysis would not yield a Significant Hazard (ie sorting is just a "routine" process step with respect to Physical/pebble hazard) particularly due to observations such as those in posts 8-10. Blame FSMA (or my inability to understand it).
Regardless. assuming a SH does exist, will presumably be necessary to apply the list of items in post 4 (et al) to determine between CCP/OPRP .
(as per the Standard, it seems to me that "PRP" is no longer a possible choice of control measure following implementation of 126.96.36.199.1).
This step involves selecting a Decision Tree. Many, many proposed decision trees exist for iso22000(2005) and at least one on this Forum for iso22000(2018). The FSSC22000 ver5 Guidance material for iso22000(2018) also offers a decision procedure but for which i have significant reservations as detailed elsewhere on this forum.
I tried the tree developed on this forum for iso22000(2018) (see link below) and the result was (easily) OPRP.
The above result is different to the (PRP) conclusion in Post 4. I'm unsure as to whether the Posts 8-10 relate to iso22000. Further comments anticipated .
(A combined control measure could probably achieve CCP but may be documentation-messy)
PS - regarding "combined sig. hazard", my apologies for the conceptual typo, should be " combined control measure", eg para 3.44.
