Explanation:

To prevent cross - contact (especially with allergens), a food worker should take steps to avoid transferring allergens. Option d involves washing hands and changing gloves before preparing an allergen - free meal. This is crucial as hands and gloves could have come into contact with allergens previously, and this step prevents that transfer. Option a is about plate washing, option b is normal fruit preparation, and option c is about cleaning after a time period, none of which are directly related to preventing cross - contact with allergens or contaminants in the context of cross - contact prevention.

Answer:

d. Washing hands and changing gloves before preparing an allergen - free meal
