Guide
No. A meat thermometer is designed for food, not the human body, and its readings should not guide health decisions. Use a clinical thermometer intended for the measurement site and follow its instructions.
A cooking thermometer is made and labeled for food. It is not a clinical device designed to measure at the mouth, armpit, rectum, ear, or forehead, so its accuracy, response, shape, and cleaning instructions are not established for those uses.
No. Even if its display covers the range of human body temperature, range is not the same as suitability. Use a clinical thermometer whose instructions name the body site you intend to measure.
Do not put a cooking probe in your mouth or use it on another body site. A pointed food probe can cause injury, and contamination can move between raw food, the device, and a person.
Choose a clinical digital or infrared thermometer intended for body-temperature measurement. Follow the manufacturer's directions for the correct site, positioning, distance, cleaning, and interpretation because methods are not interchangeable.
Do not use that result to decide whether you have a fever or whether to seek care. Take a new reading with an appropriate clinical thermometer, and clean the cooking thermometer according to its instructions before it returns to food use.
Contact a health professional if symptoms concern you, even if a reading seems normal. Seek urgent help for severe symptoms such as difficulty breathing, confusion, a seizure, or other signs of a medical emergency rather than relying on repeated temperature checks.
Common questions
No. Use a clinical thermometer designed for body-temperature measurement and for the body site in its instructions.
No. A food thermometer's displayed range does not establish that it is accurate, safe, or suitable for clinical use.
No. Cooking probes are intended for food and may be pointed or contaminated; they should not be used in the mouth or on another body site.
Do not use it for that purpose unless the manufacturer specifically identifies the device as a clinical thermometer for body-temperature measurement. FDA guidance says medical non-contact infrared thermometers must be used at the specified position and distance.
Do not substitute a meat thermometer. Base urgent decisions on symptoms and contact a health professional or local health service for advice about obtaining and using an appropriate device.

A fast, thin probe works well for portions; a heat-safe leave-in probe makes a whole roast easier to monitor.
Use a leave-in probe to track the cook and an instant-read model to check more than one spot before serving.
A fast instant-read probe is the most practical choice for steaks; insert it from the side into the center.
Start with a dependable instant-read thermometer; add a leave-in or wireless probe when you want continuous monitoring.
