Dear tsmith,
There are minor nuances between them
(BRC- Codex
haccp / iso 22000,)
IMHO, this is one of the understatements of the year!

I guess it depends on yr specific production but I am surprised you did not encounter auditor problems with traditional
CCPs which hv been demoted to OPRPs as per requirements of ISO 22000.
We have CCPs that our auditor questioned and asked our justification but when told that our cusotmers wanted them as CCPs, he had no problem.
Again, it may depend on the specifics but my first reaction is surely this is ridiculous?. I hv also met this problem previously and used the reverse logic to the customer so as to avoid (genuinely) un-necessary
CCPs. Traditionally, this was a common reason for top-heavy lists of
CCPs.
@ Jeremy, I would also be interested in knowing which
CCPs were considered inappropriate. (I recall seeing an auditing comment some time ago which indicated that plans with more than 4
CCPs tended to be more carefully checked for "necessity".)
In the near future, PAS and ISO will probably define almost everything as PRPs and remove such difficulties.
