Final answer:
Food workers with fingernail polish on fake nails must wear disposable gloves to ensure safe food handling and prevent contamination. Thorough handwashing is crucial but gloves are an additional requirement when polish or fake nails are worn.
Step-by-step explanation:
When a food worker has fingernail polish on fake nails, they must wear disposable gloves to prevent any contamination of the food being prepared or served. This is because nail polish can chip and end up in food, posing a health risk. While maintaining clean hands and nails by washing hands thoroughly is critically important, especially before starting to prepare or serve food, after using the toilet, and whenever hands become soiled, the wearing of gloves is a necessary additional precaution when fingernail polish or fake nails are present. Moreover, food workers should understand and practice proper glove use, ensuring safe food handling at all times.
