Identify potential hazards and measures for their control 2. Determine critical control points (CCP) 3. Establish critical limits which must be met to ensure each CCP is under control 4. Establish a monitoring system 5. Establish the corrective action to be taken when monitoring indicates that a CCP is not under control 6.
