What is a common symptom of foodborne illness?

Nausea is a common symptom of foodborne illness because it is the body's natural response to toxins or pathogens that may have been ingested. When harmful microorganisms or substances are detected in the digestive system, nausea often occurs as a signal for the body to expel the offending material, which can help prevent further absorption of harmful substances. This symptom frequently accompanies other gastrointestinal issues such as vomiting and diarrhea, which are also typical manifestations of foodborne illnesses. Understanding nausea in the context of food safety highlights the importance of proper food handling and preparation to prevent contamination and protect public health.
