Allergen management is treated as a chemical hazard category under HACCP and is covered by mandatory labelling laws in every major jurisdiction.

Operator dialogue

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

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

Búho & Pollito & Vaca — diálogo de operador

🐣
Piyo: ¿Los alérgenos son riesgo químico HACCP?
🦉
Poppo: Sí. Codex CXC 1-1969 categoriza alérgenos como químicos; CXC 80-2020 es el código alérgico dedicado.
🐣
Piyo: ¿Contacto cruzado vs contaminación cruzada?
🦉
Poppo: Contacto cruzado = mezcla alérgenos. Para celiacía, hasta una nube de harina de trigo es peligrosa.
🐮
Mu: Freidora dedicada sin trigo por 1.000€. Una cliente celíaca lloró de alivio — inversión recuperada.🐮
🐣
Piyo: ¿Big 9 en EE.UU.?
🦉
Poppo: FASTER Act 2021 añadió sésamo: leche, huevo, pescado, crustáceo, fruto seco, cacahuete, trigo, soja, sésamo.
🐮
Mu: Ley Natasha 2021 — todos los alimentos pre-empacados UK ahora con etiquetado completo.🐮
