Final answer:
Food handlers wearing nail polish or artificial nails are required to wear disposable gloves to ensure safety and prevent food contamination.
Step-by-step explanation:
Food handlers who are wearing nail polish or artificial nails must wear disposable gloves. This is a necessary precaution to maintain food safety and prevent contamination. While working with food, it is essential to wash hands thoroughly and keep fingernails clean to avoid transferring harmful microorganisms to the food. Washing hands before beginning to prepare or serve food, after using the toilet, and whenever hands become soiled is a part of good hygiene practices. Nail products have been known to contain toxic chemicals such as dibutyl phthalate (DBP), toluene, and formaldehyde, which are reasons why gloves are recommended to protect both the food and the food handler.
