I'm quite confused with this whole oPRP thing. Based on my assessment, our process steps which include: pasteurizer and filtration which are necessary during processing did not fall on oPRP category. Because on the following reason:
Pasteurizer - used to kill or reduce the number of pathogenic micro organisms but there is still a subsequent step that will address the remaining micro biological hazard.
- This step can be also validated and measurable which is against the principle of oPRP (only with acceptable criteria)
Filtration - Based on the severity and likelihood, the hazard address by this step is not significant because we implement preventive maintenance to address the possible hazards.
So, my question is, is it possible to have no oPRP on a HACCP plan based on ISO 22000? or are we obliged to really identify at least one oPRP?
