What is a symptom of foodborne illness?

Nausea is a common symptom of foodborne illness, as it often results from the body's reaction to consuming contaminated food or beverages. Bacteria, viruses, or toxins present in contaminated food can irritate the stomach and intestines, leading to gastrointestinal symptoms. Nausea is typically an early response to foodborne pathogens, often accompanied by other symptoms such as vomiting, diarrhea, abdominal cramps, and in some cases, fever.

Understanding the symptoms of foodborne illness is crucial for identifying and addressing potential outbreaks effectively. While other symptoms like increased heart rate, blurred vision, and headaches can occur in various medical scenarios, they are not as directly linked to foodborne illnesses as nausea is, which serves as a key indicator of digestive distress caused by pathogens in unsafe food.
