Leftovers should be refrigerated within two hours in

  • A.sealed insulated flasks
  • B.the original cooking pot, covered
  • C.shallow containers, for quick cooling
  • D.deep containers, to retain heat

Answer: C

Correct answer: shallow containers, for quick cooling

A large deep container of hot food cools from the outside inward and its centre may remain in the Danger Zone for hours, which is exactly the condition in which Clostridium perfringens spores germinate and multiply. Dividing the food between shallow containers gives a large surface area and a short conduction path, so the whole mass passes through the Danger Zone quickly. An insulated flask or a covered pot does the opposite.
