Do all food service workers need to wear hair nets?

No, not all food service workers need to wear hair nets.

While some health codes may require food service workers to wear hair nets, the specific requirements can vary depending on the jurisdiction and the type of establishment. In general, hair nets are required for food service workers who are preparing or handling food in a way that could contaminate it with hair. This may include workers who are working in the kitchen, serving food, or working in a bakery or other food preparation area.

However, there may be some exceptions to this rule. For example, some jurisdictions may not require food service workers to wear hair nets if they are working in a self-service area or if they are wearing hats or other head coverings that effectively contain their hair. Additionally, some food service establishments may have their own policies regarding hair nets, which may be stricter or more lenient than the local health code.
