Starbucks Food Safety Practice Exam

Which thermometers are approved for measuring food temperatures?

1. Digital only

2. Glass thermometers only

3. Bi-metallic stem, thermocouple, and thermistor

4. Only infrared thermometers

The correct answer is: Bi-metallic stem, thermocouple, and thermistor

The selection of bi-metallic stem, thermocouple, and thermistor thermometers is grounded in their effectiveness and reliability in assessing food temperatures accurately. Bi-metallic stem thermometers are designed to measure temperature within the food's center, providing an accurate reading, particularly for larger pieces of meat or casseroles. They have a metal stem with a dial that indicates the temperature; their design allows for easy readings of hot foods. Thermocouple thermometers, known for their rapid response times and precision, utilize a sensor that gives quick temperature readings, making them ideal for both thick and thin foods. They can measure a wide range of temperatures, which is crucial in food safety for ensuring that foods are cooked or held at safe temperatures. Thermistors, like thermocouples, offer quick readings and can be quite precise. They have a resistance that changes with temperature, which allows for accurate measurement across various food types, both hot and cold. Together, these thermometers provide a range of options suitable for different types of food items and contexts, making them the preferred choices in food safety practices. This versatility and accuracy are essential in preventing foodborne illnesses by ensuring food is cooked and stored at safe temperatures. In contrast, digital-only or
