Validation vs Verification in Food Safety: The Difference That Fails Audits
Auditors cite validation/verification mix-ups as nonconformances. Codex and ISO 22000 definitions, paired examples for cooking, cleaning, and allergen changeover.
What Is a Critical Control Point (CCP)? Definition + 5 Examples
A Critical Control Point (CCP) is the step where control prevents or eliminates a food safety hazard. Codex definition plus 5 real CCP examples with critical limits.
