When may a plain band ring be worn when preparing food?

A plain band ring may be worn when preparing food if it is made of a non-porous material, such as stainless steel or titanium, which does not harbor bacteria. It’s important that the ring is simple, without any stones or intricate designs that could trap food particles or bacteria. Additionally, the ring should be clean and properly sanitized before handling food to ensure hygiene is maintained. However, many food safety guidelines recommend removing all rings to minimize contamination risks.
