Cooking meatloaf to the correct internal temperature is essential for ensuring its safety and quality. The United States Department of Agriculture (USDA) recommends cooking meatloaf to an internal temperature of 160 degrees Fahrenheit (71 degrees Celsius) as measured by a food thermometer inserted into the center of the loaf. This temperature ensures that any harmful bacteria present in the meat have been killed, making it safe to consume.
Cooking meatloaf to the correct temperature also helps to ensure that it is cooked evenly throughout and that it has a juicy and flavorful texture. Undercooked meatloaf can be dangerous to eat, while overcooked meatloaf can be dry and tough.
