How accurate must the bimetallic dial thermometer be for inspecting the temperature of food?

The requirement for the accuracy of a bimetallic dial thermometer in food inspection is crucial to ensure food safety. An accuracy level of within plus or minus 2 degrees is essential because it allows for a reasonable margin of error while still providing reliable measurements. This level of precision ensures that food is cooked to safe temperatures, which is vital to prevent foodborne illnesses.

Food safety guidelines typically recommend that cooked foods should reach specific minimum internal temperatures to eliminate harmful bacteria, and being within 2 degrees of that target helps to ensure compliance with these standards. If temperatures were to fluctuate outside this range, it could lead to undercooked food, posing health risks. A tolerance of 2 degrees strikes a balance between necessary accuracy and practical usability, making it the standard for bimetallic dial thermometers used in food safety inspections.
