Check with a thermometer
A browned outside, an oven setting and a timer each tell a different story. A food thermometer measures internal temperature. Learn how an adult uses that measurement with the correct food category and any required rest period.
Put the habit into practice.
Name the food precisely
First decide which row of the minimum-temperature guidance applies. A whole beef chop and ground beef do not use the same rule. Ground turkey belongs with poultry. Leftovers being reheated have their own rule, and precooked ham includes a specific packaging exception. Do not choose a number because it is familiar.
Choose and prepare a suitable thermometer
Read the device instructions. Find its sensing area, required insertion depth, response time and cleaning directions. A long sensing stem may not suit a thin food; an adult can select a suitable probe and follow the correct method. Clean the probe as directed before and after use and between checks that could transfer contamination.
Measure the interior
An adult handles the hot dish and inserts the probe in the thickest part while avoiding bone, fat and gristle. Measure the food rather than the pan or air above it. Check other appropriate places or pieces when heating may be uneven. Follow the thermometer’s instructions until the reading is ready to interpret.
Keep temperature and rest together
Compare the reading with the matching rule below. For the whole-cut category and raw ham, the rest period is part of the guidance, not an optional decoration. Do not substitute a rest for reaching the required temperature. Do not transfer the rest rule to every other food category.
Know what the measurement cannot fix
A correct final reading does not reconstruct the food’s earlier storage history. Food that was mishandled may still be unsuitable, and some toxins can survive cooking. This lesson teaches measurement and category selection; it does not certify a particular meal. For practice, an adult can demonstrate the thermometer in room-temperature water without suggesting that reading proves food safety.
Guidance to keep handy
Whole meat cuts and required rest
Cook beef, bison, veal, goat, lamb and pork steaks, roasts and chops to at least 145°F (63°C), then rest for at least 3 minutes before carving or eating.
Measure internal temperature with a food thermometer. This whole-cut category is not ground meat or poultry.

Ground meat and sausage
Cook ground beef, bison, veal, goat, lamb and pork, and sausages made from these meats, to at least 160°F (71°C).
Measure internal temperature. Ground poultry and poultry sausage use the poultry rule instead. The source chart does not add a rest-time requirement to this category.

All poultry
Cook all poultry to at least 165°F (74°C): whole birds, breasts, legs, thighs, wings, ground poultry, giblets, poultry sausage and stuffing inside poultry.
Measure internal temperature with a food thermometer. The chart does not add a rest-time requirement to this category.

Casseroles
Cook meat and meatless casseroles to at least 165°F (74°C).
Includes casseroles containing meat or poultry. Measure internal temperature; an egg dish that is not such a casserole has its own category.

Eggs and egg dishes
Cook individual eggs until both yolk and white are firm. Cook egg dishes such as frittata and quiche to at least 160°F (71°C).
Casseroles containing meat or poultry use 165°F (74°C), as specified separately on the source chart.

Raw ham and required rest
Cook raw ham to at least 145°F (63°C), then rest for at least 3 minutes.
Raw ham; precooked ham for reheating has separate guidance.

Reheating precooked ham
Reheat precooked ham to 165°F (74°C). For cooked hams packaged in USDA-inspected plants, the chart specifies reheating to 140°F (60°C).
The lower value applies only to the stated USDA-inspected-plant packaged category. It is not a general leftovers rule.

Reheating leftovers
Reheat leftovers of any type to at least 165°F (74°C), measured with a food thermometer.
Only food with a safe handling and storage history. Reheating cannot reliably repair food left out too long. The chart separately specifies a packaged precooked-ham exception.

Rabbit and venison
Cook wild or farm-raised rabbit and venison to at least 160°F (71°C).
Specific chart category; do not apply the whole-cut beef rule to all game animals.

Fin fish
Cook whole fish or fish fillets to 145°F (63°C), or until the flesh is no longer translucent and separates easily with a fork.
The source chart includes salmon, tuna, tilapia, pollock, bass, cod, catfish and trout. The thermometer gives a measured temperature; this category is not shellfish.

Shellfish categories
Cook shrimp, lobster, crab and scallops until the flesh is pearly or white and opaque. Cook clams, oysters and mussels until their shells open during cooking.
These are the distinct endpoint descriptions in the FoodSafety.gov chart, not a single invented temperature for all seafood.

Measure the food’s interior
Use a food thermometer in the thickest part, avoiding bone, fat and gristle. Follow its directions for the sensing area, insertion depth, response time and cleaning.
Use a thermometer appropriate to the food’s thickness. An oven setting, cooking timer or surface reading is not the food’s internal temperature.

At the kitchen table
A situation to think through.
A recipe timer rings and a turkey burger looks brown. The timer indicates when to check; it cannot provide the burger’s internal temperature. An adult uses a suitable food thermometer and the poultry rule.
Which rule belongs to a burger made from ground turkey?
Keep these habits handy.
- Identify the food and whether it is being cooked or reheated.
- Use a food thermometer in the thickest part, avoiding bone, fat and gristle. Follow its directions for the sensing area, insertion depth, response time and cleaning.
- Cook beef, bison, veal, goat, lamb and pork steaks, roasts and chops to at least 145°F (63°C), then rest for at least 3 minutes before carving or eating.
- Cook ground beef, bison, veal, goat, lamb and pork, and sausages made from these meats, to at least 160°F (71°C).
- Cook all poultry to at least 165°F (74°C): whole birds, breasts, legs, thighs, wings, ground poultry, giblets, poultry sausage and stuffing inside poultry.
- Reheat leftovers of any type to at least 165°F (74°C), measured with a food thermometer.
- Use the full source chart for eggs, ham, game, casseroles and seafood; do not generalize one number.

For parents & educators
The adult’s part
An adult handles heat and the probe around hot food. Use an empty package and the chart to practice category selection before any real cooking. Explain device instructions rather than promising a universal insertion depth.
Talk about it
- What does the oven’s setting measure?
- Why are ground meat and whole cuts separate categories?
- What information would be missing from a photograph of a cooked meal?
Make room for different learners
Match cards for whole cuts, ground meat, poultry and leftovers to the named rules. Learners may point or explain while the adult demonstrates placement in a safe cool prop.
