What Is HACCP?
Hazard Analysis and Critical Control Points (HACCP) is the gold standard framework for food safety management, recognized by the FDA, USDA, and health departments across the country. Originally developed by NASA and Pillsbury to ensure safe food for space missions, HACCP is now the foundational approach to food safety for restaurants, institutional food service, food processors, and distributors worldwide.
HACCP is built on a straightforward principle: identify every point in your operation where a food safety hazard could occur, put controls in place at those critical points, and document everything.
Temperature monitoring is at the absolute core of HACCP. Most foodborne pathogens, including Salmonella, E. coli, and Listeria, thrive in the “danger zone” between 40°F and 140°F. Keeping food consistently outside that range, and proving it, is what HACCP is all about.
Conduct a Hazard Analysis – Identify where temperature abuse is a biological hazard risk in your operation.
Identify Critical Control Points (CCPs) – Common CCPs include receiving, cold storage, cooking, cooling, hot holding, and reheating.
Establish Critical Limits – Set specific safe temperature thresholds for each CCP (e.g., refrigeration below 41°F, hot holding above 135°F).
Establish Monitoring Procedures – Define how and how often temperatures are checked at each CCP.
Establish Corrective Actions – Document what happens when a temperature falls outside the critical limit.
Establish Verification Procedures – Confirm that the monitoring system is working correctly and consistently.
Establish Recordkeeping and Documentation – Maintain complete records of all monitoring, corrective actions, and verification – this is where most operations fall short.
The 7 Principles of HACCP
HACCP operates through seven principles, and temperature monitoring plays a direct role in nearly all of them.
