Food thermometers

In a nutshell: Probe thermometers can be used to measure the core temperature of food accurately.

Food handlers should follow the recommendations below when measuring food temperature:

The probe thermometer should be washed and disinfected before each use.
Insert the probe into the core or the thickest part of the food.
Soups and sauces should be stirred before measuring their temperature.
Do not let the probe touch the bottom of the food container.
Record the reading when the display is steady.
The probe should be washed and disinfected after each use.

If an accuracy check of the food thermometer is required, put the probe:

in a glass with 50:50 ice cubes and ice water to see if the temperature display shows a reading between -1°C and 1°C, or
in a cup of boiling water to see if the temperature display shows a reading between 99°C and 101°C.

If the temperature display do not show a reading within above temperature ranges, adjust the temperature to a correct one while the probe is still in the water. Find a professional technician for calibration if the thermometer cannot be adjusted manually, or replace it with the new one.
