What is an effective method to stop the spread of allergens in food preparation?

B is the correct choice because cleaning surfaces and utensils between uses greatly minimizes the risk of cross-contamination. Allergens can linger on work surfaces, cutting boards, and utensils, posing a risk to individuals with food allergies. By thoroughly cleaning these items with proper sanitization methods, food handlers can remove traces of allergens, ensuring a safer food preparation environment.

In food preparation, using the same cutting board for all food types can lead to unintended exposure to allergens, especially if a board used for a highly allergenic food is not properly cleaned before being used for allergen-free ingredients. Cooking all food at the same time does not address the risk of allergen transfer during preparation and may not be practical or effective in managing exposure. Storing allergens with other ingredients increases the risk of cross-contact, as accidental mixing could easily happen during food preparation or storage.
