Guide
Can You Use a Food Thermometer for Fever?
Do not use one. Select a clinical thermometer intended for body temperature and follow its site-specific directions.
Choose the right clinical format
Use a digital contact or noncontact clinical model suited to the person's age and the measurement site described in its instructions.
Keep kitchen and health equipment separate
Do not place a pointed food probe in the mouth or on the body. Separate tools prevent injury, misuse, and cross-contamination.
Act on concerning illness appropriately
A suitable thermometer is only one part of assessing illness. Follow current public-health advice and contact a clinician when symptoms warrant it.
Common questions
Questions before you buy
Can a cooking thermometer measure body temperature accurately?
It is not validated for that clinical purpose, so its reading should not guide health decisions.
Can a kitchen infrared gun be aimed at skin?
Do not substitute it for a clinical noncontact thermometer; the intended measurement method and validation differ.
What can I use if I do not own a clinical thermometer?
Obtain an appropriate clinical thermometer or ask a healthcare professional for advice rather than improvising with kitchen equipment.
Should a thermometer be shared between food and people?
No. Keep food equipment and medical equipment separate.
