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

Nausea is a very common symptom of foodborne illness and is often one of the first signs that someone has consumed contaminated food or beverages. When pathogens, such as bacteria, viruses, or parasites, enter the digestive system, they can trigger an inflammatory response, leading to nausea as the body attempts to rid itself of the harmful substances. This digestive upset is typically accompanied by other symptoms, such as vomiting and diarrhea, which are part of the body's defense mechanism against pathogens.

While appetite loss, skin rash, and dizziness can occur in certain conditions, they are not as universally recognized or common as nausea when it comes to foodborne illnesses specifically. Nausea serves as a clear indicator that something is amiss concerning food safety, prompting individuals to take action, such as seeking medical attention or addressing the contaminated food source. Understanding these symptoms can help in recognizing foodborne illnesses early, leading to better prevention and response strategies.
