Which of the following is a common symptom of foodborne illness?

Diarrhea is a common symptom of foodborne illness because it results from the body's attempt to rid itself of pathogens or toxins that have been ingested along with contaminated food or beverages. When harmful bacteria, viruses, or parasites enter the digestive system, they can disrupt the normal functioning of the intestines, leading to inflammation and excessive fluid secretion. This results in loose or watery stools, which are characteristic of diarrhea.

Other symptoms of foodborne illness may include nausea, vomiting, abdominal cramping, and fever, but diarrhea is particularly telling as it often indicates the body's response to an irritant in the gastrointestinal tract. Recognizing the symptoms of foodborne illnesses is crucial for ensuring proper health measures, including hydration and seeking medical attention if necessary.
