Hamburger meat is one of the cuts of beef needing to be cooked to at least 155⁰F. The reason for the higher temperature is E. Coli bacteria, which is deadly. It usually occurs in commercial meat processing plants when cleanliness standards are not being met. However, if you buy your own meat/sausage grinder and grind your own hamburger from fresh cold chunks of beef, it is perfectly okay to cook it medium rare. But that is the only exception.
