Explanation:
When switching tasks between raw food and ready-to-eat food, food handlers must first wash their hands. This is a crucial step in preventing cross-contamination and the spread of foodborne diseases. Hands should be washed thoroughly following the proper handwashing steps recommended by health authorities. This prevents harmful bacteria and pathogens, like Salmonella, from transferring to ready-to-eat foods which typically do not undergo further cooking to eliminate microbes.
