What should be done with food that has been left out at room temperature for too long?

• A. It can be safely eaten if it looks fine
• B. It should be thrown away
• C. It must be reheated before consumption
• D. It can be put in the refrigerator for later use

Answer: (B)

Food that has been left out at room temperature for too long should be thrown away because it may have become unsafe to eat due to the growth of harmful bacteria. When food is left out in the temperature danger zone (typically between 40°F and 140°F), bacteria can multiply rapidly, potentially leading to foodborne illnesses.

Even if the food looks and smells normal, it can still harbor bacteria that are not detectable by sight or smell. The safest practice is to discard any perishable food that has been outside of refrigeration for more than two hours (or one hour if the temperature is above 90°F). This precaution helps to prevent serious health risks associated with consuming spoiled food.
