Final answer:
The decision of how often the HACCP system will be checked for flaws and efficiency is made in the Monitoring stage of the HACCP process.
Step-by-step explanation:
The stage in which the decision of how often the entire Hazard Analysis and Critical Control Point (HACCP) system will be checked for flaws and efficiency is made is Monitoring stage in the HACCP process.
HACCP is a systematic approach to identify, evaluate, and control hazards in food production and processing to ensure food safety. The Monitoring stage involves regularly observing and verifying the effectiveness of the HACCP plan and procedures.
During the Monitoring stage, records are reviewed, measurements are taken, and observations are made to ensure that the critical control points (CCPs) are being properly monitored and that the HACCP system is functioning as intended.
