Which symptom is NOT a trigger for a food handler to stay home?

Headache is not typically considered a trigger for a food handler to stay home because it is generally not associated with foodborne illnesses or conditions that directly pose a risk to food safety. Food handlers are primarily required to remain at home when experiencing symptoms that can directly impact food safety and public health.

In contrast, jaundice, vomiting, and diarrhea are all significant symptoms that can indicate contagious diseases and have a higher potential to spread pathogens through food. Jaundice, which often signals liver issues, is especially critical because it can indicate hepatitis, a serious illness. Vomiting can easily contaminate food and surfaces, while diarrhea poses similar risks. Therefore, while headaches can be uncomfortable and may affect a food handler's performance, they do not represent a direct danger to food safety in the same way that the other symptoms do.
