Verification
Procedures
Objective
In this module, you will learn:
How to define verification
What functions are part of P plan verification
What functions are part of validation
Principle 6
Establish verification procedures
Verification
Those activities, other than monitoring, that determine the validity of the P plan and that verify the system is operating according to the plan
“Trust What You Verify”
Verification provides a level of confidence that the P plan:
is based on solid scientific principles,
is adequate to control the hazards associated with the product and process, and
is being followed
Elements of Verification
P verification activities
Calibration of monitoring devices
Calibration record review
Targeted sampling and P record review
P system verification
Observations and reviews
Microbiological end-product testing
Regulatory agencies
Validation
The element of verification focused on collecting and evaluating scientific and technical information to determine if the P plan, when properly implemented, will effectively control the hazards
Validation
Who validates the P plan?
P team
Individual qualified by training or experience
What does validation involve?
A scientific and technical review of the rationale behind each part of the P plan from hazard analysis through P verification strategy
Validation Frequency
Initially
When factors warrant, .,
Changes in raw materials
Changes in product or process
Adverse review findings
Recurring deviations
New information on hazards or control measures
On-line observations
New distribution or consumer handling practices
Examples of Validation Activities:
Cooked hamburgers
Collect data to establish that critical limits for maximum patty thickness, maximum belt speed, and minimum oven temperature will ensure that the internal temperature of every patty reaches the minimum requirement
Cooked shrimp
Verify that the internal temperature of the shrimp reaches the required temperature for the re
