Why should food handlers avoid wearing jewelry while working?

Food handlers should avoid wearing jewelry while working primarily because it can harbor pathogens and pose a risk of contamination. Jewelry such as rings, bracelets, and earrings can attract dirt and bacteria, making it easier for these pathogens to transfer to food. Additionally, loose pieces of jewelry can inadvertently fall into food, creating a physical hazard for consumers. This is particularly critical in food service settings where maintaining hygiene and preventing food contamination are essential responsibilities for food handlers.

While the other options mention various aspects related to jewelry, they do not address the primary health and safety concerns that make avoiding jewelry essential in a food handling environment.
