What is the most common symptom of foodborne illness?

The most common symptom of foodborne illness is abdominal pain. This discomfort usually occurs as a result of the gastrointestinal tract reacting to pathogens or toxins present in contaminated food. When harmful bacteria, viruses, or substances interfere with normal digestive functions, the body often responds with cramping, pain, and other digestive issues.

While headaches, no symptoms, and high fever can sometimes accompany foodborne illnesses, abdominal pain is typically the primary sign that prompts individuals to seek medical attention. It serves as a clear indicator that the body is reacting to something ingested, making it the most prevalent symptom associated with this type of illness.
