Which of the following methods is used to prevent food contamination?

Regularly washing hands and surfaces is a fundamental practice in food safety that helps prevent food contamination. The transfer of harmful pathogens, allergens, or contaminants can occur at any stage of food preparation and handling, and maintaining cleanliness is crucial.

By frequently washing hands before and after handling food, as well as cleaning surfaces and utensils that come into contact with food, the risk of cross-contamination is significantly reduced. This practice helps eliminate bacteria and viruses that can lead to foodborne illnesses. Implementing this method not only protects the food from contamination but also contributes to overall hygiene in the kitchen environment.

In contrast, storing raw meat on the top shelf can lead to contamination of other foods below through dripping juices that may carry pathogens. Using plastic utensils alone does not inherently prevent contamination unless they are also cleaned and sanitized after use. Keeping food at room temperature is also unsafe as it allows for the growth of bacteria, increasing the risk of spoilage and foodborne illness. Regular handwashing and surface sanitation directly address these risks, making it the best choice for preventing food contamination.
