Why is it safe to eat rare roast beef but not rare hamburger?

Answer 1

Here's the scoop, and you'll be able to see right through it. If any "nasty" bacteria park on meat, like on the steak, they park on the outside. (How're they gonna park anywhere else?) When a steak is cooked, the outside gets all the heat (it must penetrate to the middle) and the "nasty" things that might be on the outside take the heat and are probably cooked and killed. With ground meat, a "nasty" bug can park on the meat at any point in the cutting and grinding operation and get "mixed in" so it is on the inside. The "bugs" that might make a diner sick aren't found on the inside of a steak. They could be anywhere in the ground beef.

Answer 2

It's because hamburger is all ground up, so the bacteria on the surface of the meat will get inside and won't get killed by the cooking, since the inside is not cooked. Steak, on the other hand, is not ground up, so the bacteria stay on the outside, and should be killed by just cooking the outside. However, there is another school of thought that says that you should never order an uncooked item from a casino after a drunk night of partying. Plus, at that point, everything tastes the same anyways.

Answer 3

because hamburger has been processed
