oPRP for filtration process step
Started by carine, Jul 20 2009 09:01 AM
Dear all:
i would like to group filtration (sand filter) process step as oPRP because aftr the filtration step there is nothing control the fine particles. May i know who got such experince to contro lthe filtration step as oPRP, waht is the oPRP fromat like?? many thanks

Is it possible to have no OPRP if we can control through PRPs?
OPRP Hand Washing Procedure
Is receiving raw materials and storing them a PRP or OPRP?
Hazard assessment methodology in food for determining CCP or OPRP?
Validation Study for OPRP - Sieving Process

That should not be a problem but you will need to show that sand filtration is effective and working on an ongoing basis. You will need to have relevant limits, monitoring procedures, records, corrective actions and define responsbility/authority for these.

Hi Carine
What do you use the water for?
I would check water clarity by something more technical than visual. Why not pass though filter paper?
Every 3 days doesn't seem enough plus Corrective action - what could have happened in the previous 3 days when the filter might not have been working?

Dear Tony -C:
The water is for me to make ice. now i face the problem is, this filtration process step not a significant hazard after gone through the hazard rating matrix, if i consider it as a oPRP seem like not a logical approach. i understood that the logical sequence when there is a signicant hazard, then contol it through either oPRP or CCP, am i right?? what do u think??

If you have no further filtration then sand filtration is a ccp.
