Where should you insert a meat thermometer?
Aim for the thickest part of the food and keep the sensing section away from bone, fat and gristle. On a thin burger, chop or fish fillet, insert from the side so the tip reaches the center.

Reading a Meat Thermometer Correctly
Reading a meat thermometer correctly means finding the thermal center, keeping the sensing area away from bone and waiting until the display stabilizes. Check several locations in large or irregular food.
A food handler should monitor the thermometer until the reading does what?
Monitor it until the display stabilizes rather than recording the first changing number. The exact response time depends on the instrument, probe placement and temperature difference.
How deep must the probe go?
Identify where the sensor sits. Some digital probes sense near the tip, while a dial bimetal thermometer may need two to three inches of stem insertion; follow the manufacturer's marking and instructions.
Why should large food be checked in several places?
Roasts and whole birds heat unevenly. Move a sanitized instant-read probe through several thick areas and use the lowest valid internal reading to decide whether more cooking is needed.
How do you read poultry, steak and ground meat safely?
Match the result to the food category, not a universal target. USDA lists 165°F for poultry, 160°F for ground meats, and 145°F plus a three-minute rest for whole cuts of beef, pork, veal and lamb.
When should you question the reading?
Reposition the probe if a value changes sharply, seems inconsistent with nearby spots or may come from contact with bone or cookware. Check calibration according to the maker after a drop or suspect result.
Common questions
Questions before you buy
A food handler should monitor the thermometer until the reading what?
Until the reading stabilizes. Recording a changing display can understate or overstate the food's actual internal temperature.
How long do you leave a meat thermometer in?
For an instant-read model, leave it only until stable, then remove it. A leave-in probe may remain during cooking only when designed for that use.
Can the probe touch bone?
Avoid bone because it can produce a temperature that does not represent the surrounding meat.
Which reading counts when different spots disagree?
First rule out bad placement. For a large food, the lowest valid reading in the required check areas indicates whether cooking must continue.
Should you clean the thermometer between checks?
Yes. Follow the manufacturer's cleaning directions, especially when moving between raw and cooked food.
