A food worker who likes to wear jewelry is starting her shift and will be preparing casseroles. Which piece of jewelry may she wear while she is working?

In a food preparation environment, such as when preparing casseroles, it is important for food safety and hygiene to consider what type of jewelry is appropriate to wear. Generally, the guidelines suggest that food workers should minimize or avoid jewelry that can harbor bacteria or pose safety risks.

1. Wrist Watches: In many food service establishments, wearing a wristwatch is acceptable as it is typically easier to clean than other jewelry and does not interfere with food preparation.

2. Earrings: Small stud earrings may also be permissible as they are less likely to fall into food compared to dangling earrings.

3. Rings: Some establishments allow those who wear rings to wear plain bands, while others discourage any rings to prevent germs from getting trapped.

4. Necklaces and Bracelets: These are generally not recommended as they can easily come into contact with food or cooking surfaces.

In summary, the food worker may wear a wristwatch and small stud earrings while ensuring both personal hygiene and food safety standards are observed.
