Food Safety Certification Practice Test

At what temperature must food be held to prevent the growth of bacteria?

1. Below 32°F

2. Between 41°F and 135°F

3. Above 140°F

4. Between 135°F and 160°F

The correct answer is: Above 140°F

The correct choice is to hold food above 140°F to effectively prevent the growth of bacteria. At temperatures below 140°F, particularly within the range of 41°F to 135°F, bacteria are in the "temperature danger zone." This zone is critical as it allows bacterial growth to proliferate rapidly. Holding food at temperatures above 140°F is essential because it not only helps to keep food warm but also reduces the risk of foodborne illnesses by inhibiting bacterial growth. Maintaining food at a temperature of 135°F to 160°F is acceptable for hot holding but does not exceed the minimum temperature necessary to ensure the most significant reduction of bacterial risks. Similarly, holding food below 32°F would freeze it, which is not a viable option for preserving the quality and safety of certain food items. Overall, temperatures above 140°F are key to promoting food safety and minimizing the risks associated with foodborne pathogens.
