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

Nausea and vomiting are widely recognized as common symptoms of foodborne illness. These symptoms often arise as the body's response to harmful pathogens or toxins ingested through contaminated food or water. When the body detects these harmful substances, it activates mechanisms to expel them, leading to feelings of nausea and often resulting in vomiting.

Understanding this response is crucial in food safety as it highlights the importance of proper food handling and hygiene practices to prevent contamination. The presence of these symptoms can also serve as a valuable indicator for individuals to seek medical attention, especially in cases where multiple people experience similar symptoms after consuming the same food, suggesting a possible outbreak.
