What is a common symptom of foodborne illness?

Nausea and vomiting are common symptoms of foodborne illness because they are the body's way of expelling harmful substances or pathogens that have been ingested. When someone consumes contaminated food or drink, the gastrointestinal system reacts to the toxins or infectious agents by attempting to rid itself of them. This protective mechanism often results in symptoms such as nausea and vomiting, which can also lead to dehydration if not managed properly. Other symptoms may include diarrhea, abdominal cramps, and fever, but nausea and vomiting are particularly prominent as they directly reflect the body's response to the toxins involved in foodborne illnesses.
