What is a common symptom of foodborne illness?

Nausea and vomiting are commonly associated symptoms of foodborne illness, primarily because these reactions occur as the body’s defense mechanism in response to ingesting contaminated food or beverages. When harmful bacteria, viruses, or toxins enter the digestive system, the body attempts to expel them by triggering nausea and leading to vomiting. This helps to clear the offending substances, which can prevent further absorption and reduce the likelihood of more severe illness.

In the context of foodborne illness, nausea often precedes vomiting and may be accompanied by other gastrointestinal symptoms, such as diarrhea and abdominal cramps. Awareness of these symptoms is crucial for food handlers, as recognizing them can lead to prompt action, such as seeking medical attention for affected individuals and investigating potential sources of contamination to prevent further outbreaks.
