What is the minimum safe cooking temperature for hamburgers?

The minimum safe cooking temperature for hamburgers is 155°F. Cooking ground beef at this temperature ensures that harmful bacteria such as E. coli and Salmonella, which can be present due to the grinding process, are effectively killed. This temperature must be held for at least 15 seconds, which provides the necessary time to ensure the meat is cooked evenly and thoroughly throughout its entirety.

It's important to note that ground meats require a higher cooking temperature than whole cuts, such as steaks or roasts, which can be safely cooked to a lower temperature, like 145°F, because they have a different risk profile regarding bacteria. Cooking hamburgers to at least 155°F is a crucial food safety measure that helps prevent foodborne illnesses.
