Name one common symptom of foodborne illness.

Nausea or vomiting is a well-recognized symptom of foodborne illness, often indicating the body's reaction to infected or contaminated food. When pathogens such as bacteria, viruses, or parasites are ingested, they can irritate the gastrointestinal tract, leading the body to attempt to expel the harmful substances. This response manifests as nausea and, potentially, vomiting. These symptoms are common because they serve as protective mechanisms, helping to remove toxins or pathogens from the body.

Other symptoms associated with foodborne illnesses can include diarrhea, abdominal cramping, and fever, which are also linked to infections affecting the digestive system. Understanding these symptoms is crucial for identifying foodborne illnesses early, ensuring prompt treatment, and implementing necessary preventive measures in food safety practices.
