México: reglas de temperatura de los alimentos

“Ley” es una norma vinculante. “Orientación oficial” no es ley, pero los inspectores la esperan. “Chef Hygiene predeterminado” es un valor que la aplicación comprueba cuando ninguna norma especifica un número.

• LeyFridges keep food at 7°C at most, and cold food is served at 7°C or colder. Freezers keep food frozen (no number is set). Every fridge and freezer has a working thermometer in a visible place (NOM-251).
• LeyCook until the inside reaches at least 63°C for fish, beef joints and eggs cracked to order, 68°C for pork joints, minced beef, pork or fish and buffet eggs, and 74°C for poultry, stuffings and sausages. Reheat to at least 74°C. Keep hot food above 60°C (NOM-251).
• LeyDeliveries: chilled raw materials and fresh fish at 4°C or colder (live seafood 7°C), frozen food with no sign of thawing, frozen fish at −9°C or colder. Thaw in the fridge, by cooking, in a microwave or under cold running water, never at room temperature, and never refreeze. The day's leftovers may be used again only once, cooked again (NOM-251).
• Chef Hygiene predeterminadoNOM-251 sets no cooling time: food spends as little time as possible at room temperature. Chef Hygiene aims for 4°C in fridges and −18°C in freezers, and suggests cooling into the fridge within 2 hours: our advice, not the law.
