Why is it safe for steak to be pink in the middle but potentially dangerous for a hamburger not to be cooked all the way through?

Bacteria lives on the outside of foods, especially raw meats. When you cook a steak, you kill the outside bacteria making it safe to eat the pink insides since it won't be exposed to any bacteria. Hamburgers however are made of ground meat which, since it's ground, has been exposed to more bacteria. The meat is packed in a hamburger patty, but the inside has still been exposed to bacteria. You fully cook hamburgers to kill any lingering bacteria inside and out of the patty.

After a long conversation with my father, i learned to take my responsibilities more seriously.hope this : )

If it's a smaller child or infant, place one on the middle of the chest and on the child's back. (if it is a bigger child with enough room for two, place one on the upper right/your left of the chest, and one on the lower left/your right) the pads should never touch each other.
