What is a symptom of foodborne illness?

A symptom of foodborne illness includes manifestations such as fever and vomiting, which are common responses of the body to infections caused by harmful pathogens found in contaminated food. When individuals consume food that is contaminated with bacteria, viruses, or parasites, the body attempts to fight off these invaders, leading to symptoms like nausea, vomiting, diarrhea, abdominal cramps, and sometimes fever.

Fever, specifically, is a systemic response that indicates the body is reacting to an infection, while vomiting often occurs as a way to expel harmful substances. These symptoms help in diagnosing foodborne illnesses and understanding their severity, indicating that the body is in distress and needs careful management to prevent dehydration and other complications.

In contrast, increased energy levels, persistent cough, and increased appetite do not align with the typical responses associated with foodborne illnesses, making those options less relevant in this context.
