Hello,  

 

The  new version 2018 of ISO 22000 clearly define the difference between CCP and OPRP.

These are some points that  will  help you to properly understand the difference  of both  of them: 

 

OPRP

- The OPRPs can be used at the step or out of the process.

-  The action criterion only using for distinguishing the met criterion or not.

-  The action criterion only helps to contribute to the assurance that the acceptable level is not exceeded.

-  The monitoring method and frequency shall be proportionate to the likelihood of the failure and the severity of consequences.

 

CCP

-  The CCP is a step.

- The critical limit is exceeded or not met, the product(semi or end product) become the potential product.

-  The critical limit shall ensure that the acceptable level is not exceeded.

-  The monitoring method and frequency shall be capable of timely detection of any failure.

-  When the product affected by a failure to remain within critical limits at the CCP, the product is nonconformity.

Hi kkamel,

 

Welcome to the Forum !

 

Please clarify yr OP a little.

 

Did you mean the difference between 

 

(1) CP and OPRP

 

or

 

(2) CCP and OPRP

 

Both (1) and (2) are possible queries and are discussed in the Literature but the related responses will differ.

Hi kkamel,

 

Your question has a long history associated with it.

 

In addition to the fairly comprehensive summary in the (2018) link in Post 5, can also see these much earlier discussions -

Historically, the terminologies CP and OPRP as initially introduced/defined within a HACCP context by respectively NACMCF-1997/ISO-2005 were IMO rather dissimilar however some subsequent "interpretations"  considered them as "equivalent" (eg Surak/ IFS Standard). [the more explicit OPRP definition in  iso22000:2018 may now negate such claimed "equalisations" ] .

 

PS - One might (expanding the above) speculate that "CP" could (generically) refer to the control of any perceived hazard whereas "OPRP" be reserved for hazards considered to be "significant" (in an ISO context). Just to simplify (increase?) the confusion.
