The temperature range in which foodborne bacteria can grow is known as the 'danger zone'. This is typically considered to be between 40°F (4.4°C) and 140°F (60°C)
[1], though often 45°F (7.2°C) is considered the lower temperature of the range
[2]. According to the 2005 FDA Food Code, the danger zone is defined as 41°F - 135°F (5°C - 57°C).
Potentially hazardous food should not be stored at temperatures in this range in order to prevent
foodborne illness.
