Steak isn't sushi and should not be rare and/or expensive

[frazzled]

1. Only rare ground meat is dangerous

What about food safety? Isn't that a good reason to cook steaks all the way through? Actually, dangerous bacteria like E. coli don't live on the inside of a steak. They might live on the surface of a steak, but cooking the outside of the steak will kill them. Burgers are another story. To be safe, ground meats should be cooked well-done. But medium-rare or even rare steaks don't present any particular food safety hazard.

As this guy says, well-done steak is a crime against humanity (not to mention the poor cows). On the rare occasion (no pun) I have steak, I have it medium rare.
