Auditor gives us a non-conformance as hazard identified as biological, the control measure identified as the CCP and control measure resolves around the chlorine levels and not the micro levels.
In our HACCP plan, the control parameters of this CCP is the measure of chlorine concentration [50ppm-80ppm] to reduce the biological hazards to acceptable levels. can some one assist us as how to explain this to convice the auditor.
