Hi
Can any one help to explain the differences among PRP, OPRP, and CCP
Thanks
Dear huynh cong tai,
I assume yr post is directed to ISO22000 (or FSSC22000).
Basically all 3 categories are control measures (CM) / programs although "CCP" usually references a location / step of application. The particular focus on using such validated/verified control measures within an enlarged (ie + OPRP)
HACCP system for food safety purposes is a driving force behind the structure of ISO22000.
PRP, CCP are both defined in the ISO22000 standard and are basically the same as in most current
HACCP textbooks / Codex standards respectively which i expect you are already familiar with. More specifically
and conveniently, PAS220 (or ISO equivalent) specifies in great (and very readable) detail the scope for PRPs in ISO22000. This pioneering text illustrates how wide the scope of "PRP" has become so that it represents a proxy
CCP in much modern usage.
OPRP was invented by ISO for the ISO22000 standard in an attempt to highlight certain CMs which although not readily risk classifiable as
CCP/CMs within the traditional
HACCP process analysis were nonetheless considered to be of particular importance with respect to controlling certain other (perceived significant) hazards, eg environmental. Originally the terminology seems to have been oriented more towards certain "Operational" types of (traditional) PRP but was later re-invented within the published standard so as to cover a wider conceptual range of applicable control measures. For example, in addition to "elevated" PRPs, it can include non-traditional PRP types of activity, eg filtration. The increased (unlimited?) scope is suggested in the probabilistically vague ISO definition, eg "likelihood".
There are numerous qualitative/quantitative interpretations of OPRP in the literature, eg (a) a CM of
CCP "status" but which cannot be monitored continuously, (b) a control measure for a "significant" hazard but which has no readily monitorable (or perhaps definable) critical limits, © a control measure for a "significant" hazard but which does not conform to the requirements of a
CCP as per the traditional Codex Decision Tree (or other trees), (d) a control measure for a "significant" hazard which fails to achieve an appropriate cumulative ("CCP") score when evaluated against the standards requirements (eg 7.4.4 a-g). Some CMs are almost
defined as implemented at
CCPs such as cooking but often, as implied in ISO22004, the decision as to
CCP or OPRP is ultimately rather immaterial as long as the choice is validatably capable of achieving the intended level of control, ie a specified (acceptable) FS result.
A very condensed approach to specify OPRPs could be something like -
(a) do the
HACCP hazard analysis > significant hazards.
(b) Note whether a proposed CM is definable as a PRP.
© if no, note whether a proposed CM can be validated as achieving the specified, acceptable FS result.
(d) If yes, apply a suitable test procedure to determine whether the CM can be logically categorised as a
CCP/CM.
(e) If test result = no, > OPRP.
(Note that many other, more elaborate, system-type approaches also exist)
