The Principles of HACCP

Conduct a Hazard Analysis: The first step in a hazard analysis identifies the points in the process where hazards can be introduced. These contaminants may include:

• Physical
• Plastic, wood, metal
• Chemical
• Cleaning agents, toxins, pesticides, allergens
• Biological
• Bacteria, virus, pests, fecal matter

Identify Critical Control Points (CCPs): The next step is to identify the CCPs in the process where these hazards can be introduced into the process and pose a risk to the product end-user. For each CCP established in the previous step, a preventive measure must be identified to prevent the hazard. These may include the use of specific processing characteristics such as temperature, time, pH, salt level, and chlorine level.

Establish Critical Limits: The next step is to establish limit criteria for each CCP. A maximum or minimum limit for each relevant processing characteristic must be defined to control hazards. This represents the critical limit for the CCP. Exceeding this limit should trigger immediate corrective action for the control of all affected product.

Corrective actions have two purposes: to flag nonconforming product due to loss of control, identify the cause of nonperformance, eliminate the cause, and prevent reoccurrence. Corrective action taken before a situation spins out of control prepares you to act quickly.

Monitor Procedures: 

They should answer the following questions:

• What type of monitoring must be done for each CCP?
• How often will the measurements need to be performed to show that the process is under control?

The food safety team must outline procedures that effectively define what and how to measure and document the product at each CCP. A data analysis plan should be developed to provide the information required at each CCP.

Determine Record-Keeping Procedures: Determine what records are required to show that critical limits comply with specifications and that the system is controlling the processes as required. The records also should detail the development and operation of the system. There may be specific regulatory requirements that need to be factored into record-keeping.

Establish Verification Procedures: The goals of this analysis are to demonstrate that the system complies with all requirements. It identifies necessary updates and trends, and confirms that corrective actions are effective. The analysis is essential to planning the frequency of system audits.

This first step is validating control measures before implementation. This step shows whether the control measures manage the identified food safety hazards. It may include testing the product, arranging a scientific review, and challenging the CCPs, monitoring methods, and other validation methods.

Analysis results are used by management for the review of the HACCP plan. Validation is a critical aspect of food safety management systems and requires meticulous planning.
