Which of the following is NOT a method to prevent cross-contamination?

Using the same cutting board for all food types is not a method to prevent cross-contamination. In food safety practices, it is essential to use separate cutting boards for different types of food, especially raw meats, poultry, seafood, and fresh produce. This segregation is important because raw foods can harbor pathogenic microorganisms that could contaminate other foods if they come into contact with the same surfaces.

By using separate cutting boards, the risk of transferring harmful bacteria from raw foods to ready-to-eat foods is significantly reduced, thus enhancing food safety. Other methods listed, such as using separate utensils, cleaning surfaces, and storing food in sealed containers, are all effective strategies to minimize the risk of cross-contamination and promote safe food handling.
