Japan: regler for mattemperatur

«Lov» er en bindende regel. «Offisiell veiledning» er ikke lov, men inspektører forventer det. «Chef Hygiene standard» er en verdi appen sjekker mot der ingen regel oppgir et tall.

• LovSince 1 June 2021 every restaurant, whatever its size, writes a hygiene plan "based on HACCP thinking" (HACCPの考え方を取り入れた衛生管理), makes staff know it, records and keeps how hygiene was done, and reviews the plan (Enforcement Regulation, Art 66-2). Most follow an industry handbook (手引書) that MHLW lists.
• LovFridge 10°C or colder and freezer −15°C or colder are the legal storage standards for listed foods (such as meat at 10°C and frozen foods at −15°C), and the daily check in MHLW's listed handbook. Fridges, freezers and heating equipment have thermometers. Chef Hygiene aims for 5°C and −18°C as good practice, not the law.
• Offisiell veiledningMHLW's guidance (its Mass-Cooking Facility Hygiene Manual): cook to a core of 75°C for at least 1 minute (bivalves such as oysters 85–90°C for 90 seconds), keep cooked food at 65°C or hotter (or 10°C or colder), cool it to about 20°C within 30 minutes or about 10°C within 60 minutes, and eat it within 2 hours of cooking.
• Offisiell veiledningNo official reheating temperature: the small-restaurant handbook judges reheating by bubbling, look and temperature. Chef Hygiene uses 75°C only as a probe guide.
• Chef Hygiene standardChef Hygiene asks for fridge checks at opening and closing. That is our choice: the handbook's daily sheet is filled in at the end of the day.
