Dear vera,
IMHO, this BRC para which you refer is another pseudo - ISO clone as evidenced by the word "appropriate". It is basic and correct in standard HACCP techniques to require verification. The exact interpretation is typically arbitrary and many people write their own understanding of the term into their HACCP plan, eg checked by an authorised person, eg HACCP Coordinator, within 24 - 48 hrs whatever. It is also obviously stated that failures of critical points are dealt with immediately. An additional random time - based sampling of this data by a third person is added to reinforce the procedure, perhaps for a 6-month review.
However, in my inspectorial experience, it is typical to see pages of beautiful columns of 100% countersigned data on monitoring sheets all ready for the auditor up to the day he/she arrives. Both parties know that the the verifier would have to be superhuman to actually "audit" this volume of data. Typical examples are 1hr outputs from metal detectors.
To summarise, one cannot say the procedure is wrong, more of a necesary evil.
