The most effective way to prevent cross-contamination in food services is through proper handwashing between tasks. This practice is critical because it helps eliminate harmful pathogens that can transfer from one food item to another, especially when handling raw foods, such as meats, vegetables, and fruits. Effective handwashing removes any contaminants that may be present on a food handler's hands, significantly reducing the risk of foodborne illnesses.

By ensuring that hands are cleaned thoroughly with soap and water after handling each type of food, particularly after touching raw items, food handlers break the cycle of contamination. It's important to focus on this key step since harmful bacteria can easily spread from one food item to another, posing serious health risks to consumers.

Other practices, like using the same utensils for all food or storing raw and cooked foods together, can actually contribute to cross-contamination rather than preventing it. Eating food within an hour does not address contamination; it is more about food safety after preparation, rather than preventing the initial risk of cross-contamination. Therefore, proper handwashing is essential for maintaining a safe food handling environment.
