Because ground meat has been a significant source of foodborne illness, the USDA advises consumers to use a meat thermometer when cooking burgers. In other words, you should not rely on eyeballing the internal color of the meat to ensure it’s safe to eat.
The agency’s research has shown that the color of meat is not a reliable indicator of ground beef safety. To be safe from harmful bacteria such as E. coli, ground beef must be cooked thoroughly to 160°F: thoroughly well done. This recommendation applies to all ground beef, including meat balls and meat loaf.
Why, then, can you eat steak as rare as you like?
When a steak, roast or other cut of beef is cooked, the heat kills all the bacteria, which are on the surface of the meat.
When beef is ground, however, the bacteria are dispersed to every individual ground bit. They’ll be killed if they’re on the surface of the meat that’s exposed to the heat. But unless the ground beef is cooked to 160°F, any harmful bacteria inside the beef/meat ball/meat loaf will still be viable.
If you love your beef medium rare—and we do—you have options to limit your exposure. While there are no guarantees, you can:
O.K., so where’s the beef? Otherwise asked, how to you get your burger or steak to the desired degree of doneness?
If you don’t have a meat thermometer, you can try it by touch. While that’s not what the USDA advises, that’s how chefs in every restaurant do it. See this simple meat doneness pictorial and try it.
