Break apart the cooking meat with the spatula to get the chunks smaller if desired. Cook the ground beef for eight to 10 minutes or until no pink remains in the middle of the pieces. The USDA recommends cooking ground beef until it reaches an internal temperature of 160 degrees Fahrenheit.
130F with a rest (covered) should be hot enough. Ground beef really should be cooked to 155 degrees. Ground beef needs to be cooked to a higher temperature than other beef. Firstly because of its higher fat consistency and closer texture (denser). Secondly because unlike an integral cut of meat, ground beef has been exposed to more bacteria.
