How can harmful bacteria be prevented from contaminating food?

1. By cooking food at high temperatures

2. By avoiding handwashing

3. By using the same cutting board for meat and vegetables

4. By thawing food quickly at room temperature

The correct answer is: By cooking food at high temperatures

Cooking food at high temperatures is an effective way to prevent harmful bacteria from contaminating food because it kills pathogens that may be present. Many bacteria thrive at certain temperature ranges and can cause foodborne illnesses if not eradicated through proper cooking. By reaching the appropriate internal temperature for different types of food (such as poultry, beef, and seafood), you significantly reduce the risk of food contamination. It's essential to note that other methods, such as proper handling and hygiene practices—including thorough handwashing and separate cutting boards for different food types—play vital roles in food safety as well. However, cooking at high temperatures specifically targets the elimination of dangerous bacteria, making it a crucial step in ensuring food safety.
