Controlling time and temperature is crucial for preventing foodborne illness because many harmful bacteria thrive in specific temperature ranges, known as the danger zone, typically between 41°F and 135°F. Keeping food at safe temperatures slows down the growth of pathogens, as well as ensuring that food is cooked to the required internal temperatures to kill potential bacteria.

Maintaining proper time limits for how long food can be left out, whether cooked or raw, is also essential. For example, perishable items should not be left at room temperature for more than two hours. This control helps minimize the risk of foodborne illness outbreaks. The other options do not promote safety; for instance, a noisy environment can lead to miscommunication of food handling practices, increasing food exposure time allows bacteria to proliferate, and using expired ingredients risks contamination and illness.
