Which of the following is a method to prevent cross-contamination?

Using separate cutting boards for raw meats and vegetables is an essential method to prevent cross-contamination. This practice significantly reduces the risk of harmful bacteria from raw meats being transferred to fresh produce that will be consumed without further cooking. Each type of food can carry different pathogens; for example, raw meats can harbor bacteria like Salmonella or E. coli, while vegetables may not. By having designated cutting boards for each food category, food handlers can ensure that utensils and surfaces are not unintentionally contaminated.

The practice of using separate cutting boards forms part of a broader food safety strategy known as "separation" or "segregation," which is pivotal in maintaining safe food handling protocols in both home and commercial kitchens. This method is especially crucial in preventing foodborne illnesses that can arise from cross-contaminated foods.
