Bacteria multiply rapidly in the Danger Zone â temperatures between 40 and 140 Â°F (4.4 and 60 Â°C). To keep bacterial levels low, store ground beef at 40 Â°F (4.4 Â°C) or below and use within 2 days, or freeze. To destroy harmful bacteria, cook ground beef to a safe minimum internal temperature of 160 Â°F (71.1 Â°C).hange the water every 30 minutes. Cook immediately. Do not refreeze raw ground meat thawed in cold water or in the microwave oven unless you cook it first. Never leave ground beef or any perishable food out at room temperature for more than 2 hours (1 hour at 90 Â°F and above).
So you need to cook it through to kill the bacteria. In steak only the outside has come into human contact so the center has no dangerous bacteria in it. Therefore only the outside needs to be seared. Cook beef to a temperature of at least 160Â° (71Â°). Ground beef should be cooked until all pink color is gone, but do not rely only on color. Check the temperature with a meat thermometer. Split open restaurant and home-cooked hamburgers to ensure that they have been completely cooked.
