What is the defined temperature range known as the danger zone for rapid bacterial growth?

Answer

Between $40^{\circ}\text{F}$ and $140^{\circ}\text{F}$ ($4^{\circ}\text{C}$ and $60^{\circ}\text{C}$)

Bacteria multiply rapidly when food is held between $40^{\circ}\text{F}$ and $140^{\circ}\text{F}$ ($4^{\circ}\text{C}$ and $60^{\circ}\text{C}$). Safe food management requires keeping food either thoroughly hot or properly cold, outside of this range.
