Jon Isn't having burgers cooked rare or medium-rare, akin to cooking steaks rare or medium-rare, one of those things popular with hipsters? Bacteria in steaks are confined to the surface, so that just cooking the outside is okay, as those bugs are killed. If the steak is minced, then the bugs on the surface are incorporated throughout the mince. Unless the burger is well cooked, the bugs in the middle aren't killed and potentially can still cause food poisoning.
