What method is best for ensuring food is cooked thoroughly?

Using a food thermometer is the most reliable method for ensuring that food is cooked thoroughly. This tool provides an accurate measurement of the internal temperature of the food, which is crucial for determining whether harmful bacteria have been killed and whether the food is safe to eat. Different types of food require specific internal temperatures to be considered safe. For example, poultry should reach at least 165°F, while ground meats need to reach 160°F. A food thermometer eliminates guesswork and helps prevent undercooked food that could lead to foodborne illness.

Other methods, such as tasting or estimating cooking time, can be subjective and may not guarantee safety. Cooking on high heat may not evenly cook the food, leading to parts being undercooked while the outside may appear done. Thus, relying on a food thermometer is the best practice in maintaining food safety.
