Which is an example of time-temperature abuse?

• A. Leaving perishable foods at room temperature for more than 2 hours
• B. Keeping cold foods at 40°F or below
• C. Freezing foods
• D. Cooking to 165°F

Answer: (A)

Time-temperature abuse happens when food spends too long in a temperature range where bacteria multiply quickly, the temperature danger zone. Perishable foods left at room temperature for more than two hours sit in that danger zone, giving bacteria time to grow to higher levels and increasing the risk of foodborne illness. The other actions describe proper temperature control: keeping cold foods at 40°F or below slows or stops growth, freezing foods halts growth, and cooking to 165°F reduces or eliminates pathogens. So the scenario of leaving perishable foods at room temperature for more than two hours is a classic example of time-temperature abuse.
