Internal temperature refers to the temperature of what?

• A. The outside of the product
• B. The inside of the product
• C. The surface of the product
• D. The ambient air

Answer: (B)

Internal temperature is the temperature inside the food itself, usually measured in the center. It matters because safety and doneness depend on heating the interior to a level that reduces pathogens, not just the outside. The exterior or surface of the product can be hot while the inside remains undercooked, so checking the interior ensures the entire item has been heated enough. To measure it correctly, insert a calibrated thermometer into the thickest part of the product, away from bone and fat, and avoid checking only the surface. Also keep in mind that the interior can continue to rise a bit after removal from heat (carryover cooking), so you may pull it from heat when it’s near the target and let it finish safely.
