Cooking meatloaf to the proper internal temperature is crucial for both safety and flavor. The United States Department of Agriculture (USDA) recommends cooking ground beef, pork, lamb, and veal to an internal temperature of 160 degrees Fahrenheit (71 degrees Celsius). This temperature ensures that any harmful bacteria present in the meat have been killed. However, some people prefer to cook their meatloaf to a higher internal temperature, such as 165 degrees Fahrenheit (74 degrees Celsius), for a more well-done texture. Ultimately, the decision of what temperature to cook meatloaf to is a matter of personal preference.
In addition to safety, cooking meatloaf to the proper internal temperature also affects its flavor and texture. Meatloaf that is cooked to a lower internal temperature will be more moist and tender, while meatloaf that is cooked to a higher internal temperature will be more dry and crumbly. The ideal internal temperature for meatloaf is one that balances both safety and flavor. For most people, this temperature is between 160 degrees Fahrenheit (71 degrees Celsius) and 165 degrees Fahrenheit (74 degrees Celsius).
