Utah Food Safety Practice Test

What is the minimum depth that a bimetal thermometer’s stem must be inserted into food for accurate readings?

1. 1 inch

2. 2 inches

3. 3 inches

4. 4 inches

The correct answer is: 2 inches

For accurate readings, a bimetal thermometer's stem must be inserted a minimum of 2 inches into the food. This depth ensures that the sensor at the tip of the thermometer is adequately surrounded by the food mass, allowing it to measure the food's internal temperature accurately. When a thermometer is inserted too shallowly, it may not record the true temperature of the food, leading to potential food safety risks. By following the guideline of inserting the stem to a depth of 2 inches, food handlers can ensure they are measuring the temperature where it matters most, particularly in thick or dense food items, which may have temperature variations. This practice is crucial in preventing foodborne illnesses and ensuring that food is cooked and maintained at safe temperatures.
