Safe internal temperatures

The numbers to know for poultry, meat, fish and eggs.

All temperatures on this page are official figures from the USDA Food Safety and Inspection Service and the UK Food Standards Agency. CookTheGuide does not set or modify these values.

Safe minimum internal temperatures

Measured with a probe thermometer at the thickest part, not near bone.

Food °C °F Authority
Poultry, whole or ground 74 165 USDA
Ground beef, pork, lamb 71 160 USDA
Egg dishes 71 160 USDA
Beef, pork, lamb: steaks, chops, roasts (rest 3 min) 63 145 USDA
Fish and shellfish 63 145 USDA
Leftovers and casseroles 74 165 USDA

Whole cuts of pork, beef, veal and lamb require a 3-minute rest after reaching 63 °C. Full USDA chart →

Why temperature matters, not colour

Colour is not a reliable indicator of doneness. Pork can be pink and safe at 63 °C; chicken can look white and be undercooked. The only way to know is a probe thermometer. The USDA explains why colour misleads — myoglobin levels, packaging gases and pH all affect colour independently of temperature.

How to use a probe thermometer correctly

  1. Insert the probe into the thickest part of the meat, not touching bone or fat.
  2. For burgers and thin cuts, insert horizontally from the side so the tip is in the centre.
  3. Wait for the reading to stabilise (2–3 seconds for instant-read; up to 20 seconds for dial types).
  4. Check the USDA thermometer accuracy guide — test yours in ice water (should read 0 °C) and boiling water (100 °C at sea level).

The danger zone

Bacteria multiply most rapidly between 4 °C and 60 °C (40–140 °F) — the "danger zone." Keep food out of this range as much as possible. Do not leave cooked food at room temperature for more than 2 hours (1 hour above 32 °C). Source: USDA — The Danger Zone.
