Which symptom is NOT a reason to remove a worker from handling food?

Headaches are often not considered a valid reason to remove a worker from handling food because they are not typically associated with contagious illnesses that could be transmitted through food. While headaches can be uncomfortable and may affect a person's ability to work, they do not directly pose a risk to food safety.

On the other hand, symptoms such as fever, nausea, and vomiting are indicative of possible foodborne illnesses or infections. These symptoms could lead to the contamination of food if a worker were to handle it while experiencing them, thereby posing a health risk to consumers. Thus, while it is crucial for food handlers to report any symptoms they experience, only certain symptoms, especially those suggesting infectious illnesses, necessitate immediate removal from food handling duties to ensure the safety and health of others.
