How hot does the inside of a hamburger need to get to be safe to eat?

Hamburgers are safe at 160°F inside, hotter than a steak because grinding mixes germs into the middle.

  1. 145°F, same as a steak
  2. 165°F, same as chicken
  3. 160°F ✔

Why: Grinding mixes germs from the outside of the meat into the middle, so burgers need more heat than a steak does. Color can fool you, so check with a food thermometer.

Huh, didn't know that: Color can fool you, so check with a food thermometer.
