Question

In order to make sure that thermometers will accurately take the temperature of foods, they must (check all that apply):

O Be accurate to +/-2∘F
O Be calibrated before each shift

Answer 1

Thermometers used for measuring food temperatures should be accurate to +/-2°F and must be calibrated before each shift to maintain accuracy for food safety.

Step-by-step explanation:

In order to ensure that thermometers accurately take the temperature of foods, it is essential that they meet certain criteria. According to best practices, a food thermometer should be accurate to +/-2°F to ensure reliable reading. Moreover, thermometers ought to be calibrated before each shift to maintain this level of accuracy, thus safeguarding against potential food safety issues caused by incorrect temperature readings. Regular calibration is crucial because thermometers can lose their accuracy over time or after being bumped or dropped. Using well-defined temperature scales such as Fahrenheit, Celsius, and Kelvin, and ensuring the correct functioning of thermometers by routine calibration, helps to make sure food reaches a high enough temperature to kill any bacteria it might contain.
