Choose instant-read or leave-in use
Use an instant-read thermometer for quick checks near the end of cooking. Insert a leave-in probe before or during cooking only when the manufacturer rates the probe, cable and connector for that appliance.

Guide
Put the sensing area in the coldest part of the food, away from bone and cookware. Check multiple spots, compare with current USDA guidance and clean the probe after each use.
Use an instant-read thermometer for quick checks near the end of cooking. Insert a leave-in probe before or during cooking only when the manufacturer rates the probe, cable and connector for that appliance.
Aim for the center of the thickest section and avoid bone, fat pockets and the pan. For thin foods, insert from the side so more of the sensing area sits inside the food.
A leave-in model tracks the rise continuously; a handheld model is removed after the reading stabilizes. Do not leave an instant-read thermometer in the oven.
Large or irregular foods heat unevenly. Move the probe and use the lowest valid reading when comparing the food with the safe endpoint.
Wash the food-contact portion according to its manual after each use, especially between raw and cooked food. Do not immerse the display unless its protection rating explicitly allows it.
Body thermometers are designed for a narrow human-temperature range and are not food tools. Infrared forehead devices measure surface conditions and cannot confirm a food's internal temperature.
Common questions
No. Kitchen thermometers are not medical devices and are not designed or validated for diagnosing body temperature.
No. Its range, probe construction and sanitation instructions are intended for people, not hot food or cooking equipment.
Insert it beforehand only if it is a leave-in model rated for the appliance. Use an instant-read thermometer for checks during or near the end of cooking.
Use a purpose-built food thermometer. Household, outdoor and medical thermometers may have unsuitable ranges, materials or response times.
Yes: leave-in probes monitor continuously, while instant-read probes provide brief spot checks. Follow the exact model's heat limits.
