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

Nausea and vomiting are recognized as common symptoms of foodborne illness because they are direct responses of the body to harmful pathogens or toxins ingested through contaminated food or beverages. When harmful microorganisms like bacteria, viruses, or parasites enter the gastrointestinal tract, they can irritate the stomach lining, leading to a range of digestive symptoms.

Foodborne illnesses, such as those caused by Salmonella or E. coli, often manifest through gastrointestinal distress. Nausea occurs as the body attempts to expel the harmful substances, and vomiting serves as a protective mechanism to eliminate them from the system. In many cases, these symptoms will appear within hours or days after consuming contaminated food, which is critical for identifying potential outbreaks.

While coughing, headaches, and sore throat can occur due to a variety of illnesses, they are not typical indicators of foodborne infections. Instead, nausea and vomiting directly indicate an issue within the digestive system, making them a hallmark symptom of foodborne illness. Understanding these symptoms is crucial for food safety practices and recognizing when to seek medical attention.
