What it is, in one paragraph

Foodborne illness surveillance data tells operators which hazards must be designed against. WHO[1], the U.S. CDC, ECDC, and Japan’s NIID publish annual incidence; in international, the operator should design control measures against the top three pathogens locally reported[2].

Operator dialogue

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

🐣
Piyo: Poppo-san, where does foodborne illness 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: foodborne illness made blissful for everyone in the kitchen.

Owl & Chick & Cow — an operator dialogue

🐣
Piyo: How big is foodborne illness globally?
🦉
Poppo: WHO estimate: 600 million cases annually, 420,000 deaths. Same scale as TB or road accidents.
🐣
Piyo: That's huge.
🦉
Poppo: Codex frames food safety as a human right. International standardisation is therefore non-optional.
🐮
Mou: Once a month I review MHLW outbreak data. Knowing 'norovirus is up' lets us tighten controls in advance.
🐣
Piyo: Norovirus only in winter?
🦉
Poppo: Mostly Nov-Feb, but oysters can deliver it year-round. Each pathogen has its season.
🐮
Mou: Last year a customer complained of stomach pain. We re-checked egg cooking temps — found a gap. Fixed.
🐣
Piyo: Strong, kind, beautiful — never let a near-miss go to waste.
