Thermometers that measure temperatures in Fahrenheit only must be accurate to what degree?

Thermometers that measure temperatures in Fahrenheit only must be accurate to within 2°F. This standard is set to ensure that food safety practices are adequately maintained. Accurate temperature measurement is crucial in food service and food safety, as even minor deviations can lead to foodborne illnesses or spoilage.

Being accurate to 2°F allows for a reasonable buffer in temperature readings, ensuring that food is cooked, held, and stored at safe temperatures. This accuracy is particularly important when it comes to hot food holding and cold food storage, as improper temperatures can promote the growth of harmful bacteria.

Furthermore, the ability to achieve this level of accuracy means that operators can trust the readings of their thermometers, and subsequently, ensure that food safety protocols are being followed effectively. In a regulatory context, maintaining this accuracy also aligns with guidelines from health authorities, which emphasize the importance of proper temperature control in food safety.
