What it is, in one paragraph

Internal and third-party audits are how a food-safety management system stays honest between regulator visits. ISO 22000:2018[1] and the GFSI-recognised standards (FSSC 22000, BRCGS, SQF) define the audit framework most large operators follow[2]. In international, the national regulator typically accepts audit evidence under those frameworks[3].

The 12 terms you must know

  4. Critical Limit — defined in Codex Annex II and operationalised by national authorities.

Operator dialogue

🦉 & 🐣 & 🐮 — A 5-round operator’s dialogue

🐣
Piyo: Poppo-san, where does audit actually start in a real kitchen?
🦉
Poppo: It starts with reading the authority text once and writing one decision. Codex sets the international baseline; your national regulator binds you to a specific value or method.
🐣
Piyo: What if the staff resist the new rule?
🦉
Poppo: Show them the failure mode it prevents and the time it saves. Authority handbooks (FSA SFBB, MHLW small-business guidance) describe the minimum viable system — you adapt, you don’t reinvent.
🐮
Mou: Strong, kind, beautiful: audit made blissful for everyone in the kitchen.

Owl & Chick & Cow — an operator dialogue

🐣
Piyo: Internal vs third-party audit?
🦉
Poppo: Internal: independent within the company. Third-party: GFSI-recognised body (FSSC/BRCGS/SQF) — needed for certification.
🐣
Piyo: CAPA?
🦉
Poppo: Corrective and Preventive Action. Find → analyse root cause → act → verify.
🐮
Mou: After a temperature excursion last year, 5-Why led to 'fridge in direct sunlight'. Layout change — solved.
🐣
Piyo: FSSC 22000 vs ISO 22000?
🦉
Poppo: FSSC bundles ISO 22000 + ISO/TS 22002 (PRP) + extra requirements — GFSI recognises it.
🐮
Mou: Big retailers and exporters often require GFSI certification. We're working towards it.
🐣
Piyo: Strong, kind, beautiful — audit is the mirror that polishes daily life.
