What sort of thermometers are required – probe or infrared?
When a food business handles potentially hazardous foods they are required to have a probe type thermometer accurate to + or – 1oC to be able to accurately measure the temperature of these foods. Infrared thermometers are useful but only measure the surface temperature of the foods – e.g. one could not be confident that the inside of a chicken has reached a certain temperature when using a infrared thermometer.
