HACCP Principles
Hazard Analysis and Critical Control Points (HACCP) System
HACCP is a systematic approach to identifying, evaluating, and controlling food safety hazards throughout the production process. Rather than relying on end-product testing alone, HACCP focuses on prevention: catching hazards before they reach the consumer.
The system is built on seven principles:
- Conduct a hazard analysis — Identify biological, chemical, and physical hazards at each step of production.
- Determine Critical Control Points (CCPs) — Find the specific points where control can prevent, eliminate, or reduce a hazard to an acceptable level.
- Establish critical limits — Set measurable boundaries (e.g., minimum cooking temperature) that must be met at each CCP.
- Establish monitoring procedures — Define how and how often each CCP will be checked.
- Establish corrective actions — Specify what happens when a critical limit is not met.
- Establish verification procedures — Confirm the overall HACCP plan is working as intended.
- Establish record-keeping and documentation — Maintain written records of all monitoring, corrective actions, and verification activities.
Developing a HACCP plan requires a thorough understanding of the food production process and the potential hazards associated with each step. The system is widely recognized and adopted across the global food industry.
Critical Control Points (CCPs) and Prerequisite Programs
A CCP is a specific point, step, or procedure in production where control can be applied to prevent, eliminate, or reduce a food safety hazard to an acceptable level. Common examples include cooking (reaching a target internal temperature), cooling (bringing temperature down within a set time window), and metal detection (screening for physical contaminants before packaging).
Not every food safety measure is a CCP, though. Prerequisite programs form the foundation of the entire food safety system by providing the basic environmental and operating conditions needed to produce safe food. These include:
- Good Manufacturing Practices (GMPs) — General rules for facility design, equipment maintenance, and personnel hygiene.
- Good Hygiene Practices (GHPs) — Standards for personal cleanliness, handwashing, and preventing cross-contamination.
- Sanitation Standard Operating Procedures (SSOPs) — Detailed, written instructions for cleaning and sanitizing equipment, utensils, and facilities. SSOPs specify things like cleaning schedules and required sanitizer concentrations.
Think of it this way: prerequisite programs keep the overall environment safe, while CCPs target the specific high-risk steps where hazards must be controlled.
Food Safety Management Systems
ISO 22000 and Good Agricultural Practices (GAP)
ISO 22000 is an international standard that specifies requirements for a food safety management system. It incorporates HACCP principles alongside other internationally recognized food safety standards into a single framework. One of its strengths is its broad scope: it applies to all organizations in the food chain, from feed producers and farms through manufacturers, transport and storage operators, and retailers.
Good Agricultural Practices (GAP) are voluntary guidelines focused on the farm level. They address environmental, economic, and social sustainability for on-farm processes, with the goal of producing safe, quality food and non-food agricultural products. GAP covers areas such as:
- Soil management and water quality
- Pest control through integrated pest management (IPM)
- Proper use of fertilizers and pesticides
- Worker health and safety
Where ISO 22000 provides a management system for the entire supply chain, GAP zeroes in on getting things right at the very start of that chain.
Food Defense and Traceability
Food defense is distinct from general food safety. While food safety addresses unintentional contamination (spoilage, cross-contamination), food defense focuses on protecting the food supply from intentional contamination or adulteration by biological, chemical, physical, or radiological agents. Food defense programs involve measures to prevent, detect, and respond to deliberate threats, including access control to production areas, employee background checks, and crisis management plans.
Traceability is the ability to track a food product and its ingredients through all stages of production, processing, and distribution. If a food safety incident occurs, traceability enables quick identification and removal of affected products from the market, limiting consumer exposure.
Traceability is achieved through:
- Proper record-keeping at each stage of the supply chain
- Clear labeling of products and ingredients
- Unique identifiers such as lot numbers, barcodes, and radio-frequency identification (RFID) tags
Together, food defense and traceability add layers of protection that go beyond what HACCP and prerequisite programs address on their own.
