How it works

  2. 2Remaining safe time = 24 × 2 − 10 = 38 h
  3. 3Reheat thoroughly before the window ends
Cooked food left over 2 hours at room temperature breeds bacteria fast; seal and refrigerate while still warm. Leafy greens raise nitrite overnight, so finish them in the same meal; cold dishes and braised food must never be kept overnight. Reheat to a rolling 100°C for 3+ minutes, and only reheat once. The fridge is not sterile — Listeria still grows slowly at 4°C; discard anything slimy, sour, or off-smelling.
