New York City Food Protection Practice Test

What is the acceptable range for bi-metallic stem thermometers?

1. 0°F to 100°F

2. 0°F to 180°F

3. 0°F to 220°F

4. 0°F to 250°F

The correct answer is: 0°F to 220°F

The acceptable range for bi-metallic stem thermometers is 0°F to 220°F because these thermometers are specifically designed for accurately measuring the temperature of food and other materials within this range. The bi-metallic stem thermometer uses a metal probe with a sensing element that detects temperature changes, making it ideal for both cold and hot food items. This range allows for efficient monitoring of food safety, as it covers the critical temperatures needed to ensure food is cooked, held, and served safely, especially in environments like restaurants where temperature control is paramount to prevent foodborne illnesses. The upper limit of 220°F also accommodates situations that may require the measurement of boiling liquids, which can be essential in culinary practices. Ranges outside this limit, such as those presented in the other options, would not be as effective for food safety monitoring, as they either fall short of temperatures required for proper food preparation or exceed typical cooking and holding temperatures.
