Hi lavtak,
I wouldn’t get hung up too much on whether your control of a hazard is by a PRP or an OPRP as long as you have a logical assessment and the hazard is in control. Some relevant info from CODEX and ISO 22000 is posted below.
CODEX General Principles of Food Hygiene:
Depending on the nature of the food, food process, and the potential for adverse health effects, to control hazards it may be sufficient to apply GHPs, including, as appropriate, some that require more attention than others, as they have a greater impact on food safety. When the application of GHPs alone is not sufficient, a combination of GHPs and additional control measures at CCPs should be applied.
ISO 22000 8.5.2.4 Selection and categorization of control measure(s):
8.5.2.4.1 Based on the hazard assessment, the organization shall select an appropriate control measure or combination of control measures that will be capable of preventing or reducing the identified significant food safety hazards to defined acceptable levels
So if you have a significant hazard you need to have appropriate control measures in place with appropriate monitoring, corrective action if necessary and verification.
Regarding my point regarding the important thing is for you to control your hazard (rather than worry whether you should call it a PRP or an OPRP) and GMO’s comment regarding failures of prerequisites, below are some statistics I quote in the IFSQN Practical HACCP Training:
FDA Recalls, Market Withdrawals & Safety Alerts - Analysis of FDA Recall Notices from 2017 onwards shows:
51% of the alerts were due to incorrect labelling/undeclared allergens.
34% were due to contamination with well known environmental pathogens Salmonella and Listeria.
I would think the majority of which would have been due to failure of prerequisites rather than CCPs.
Kind regards,
Tony
