In our processes we have installed extreme grate magnets and in our HACCP plan we have identifed as oPRP and we have maintained a cleaning at our bagging before metal detection every 4 hours. Idid not write a specific SOp and now it is becoming mandotory on
making sure is how they clean
avoid dropping the magents - loose its strength
measuring in gauss or LBS - which is appropriate
Will appreciate the comments and feedback and if one has an SOp to share
