Which of the following is an example of a potentially hazardous food that should not be left in the danger zone beyond the 2-hour limit?

• A. Fresh fruit
• B. Bread
• C. Cooked meat
• D. Raw vegetables

Answer: (C)

The main idea here is that some foods are more able to support rapid growth of bacteria when kept at room temperature, so they must be kept out of the danger zone or cooled quickly. Cooked meat fits this description because after cooking it contains moisture and nutrients that are ideal for microbes to multiply if it’s left in the range of 41°F to 135°F (about 5°C to 57°C). When such foods sit at room temperature for too long, bacteria can reach dangerous levels, and some toxins may form that aren’t fully destroyed by reheating. That’s why the two-hour rule is applied to cooked meats to keep them safe.

Fresh fruit, bread, and raw vegetables generally don’t provide the same combination of moisture, protein, and neutral pH that favors rapid bacterial growth, so they’re not considered potentially hazardous in the same way.
