Food should not be left out of refrigeration for longer than

  • A.thirty minutes
  • B.eight hours
  • C.two hours
  • D.six hours

Answer: C

Correct answer: two hours

Two hours is the standard cumulative limit for food held between 40 and 140 degrees Fahrenheit. It is chosen so that even a substantial initial contamination cannot multiply to a hazardous level within the time allowed. The limit halves to one hour when the ambient temperature exceeds 90 degrees, since growth is then faster still.
