Which symptom is typically not associated with foodborne illness?

The symptom that is typically not associated with foodborne illness is cough. Foodborne illnesses are primarily characterized by gastrointestinal symptoms due to the ingestion of contaminated food or beverages. Common symptoms include fever, diarrhea, and vomiting as the body attempts to rid itself of harmful pathogens or toxins.

A cough, while it may be present in many other illnesses, especially those related to respiratory infections, is not a standard symptom of foodborne illness. It does not relate to the mechanisms of infection or poisoning that commonly underlie foodborne outbreaks. Instead, the body's response to foodborne pathogens tends to manifest with symptoms affecting the digestive system rather than the respiratory system.
