What are the symptoms of foodborne illness?

The symptoms of foodborne illness are primarily gastrointestinal and may include nausea, vomiting, diarrhea, fever, and abdominal cramps. These symptoms result from the body's response to harmful bacteria, viruses, or parasites that may be present in contaminated food or beverages.

Nausea and vomiting often occur as the body tries to rid itself of the offending pathogens, while diarrhea can be a way for the body to flush out toxins. Fever is a common response to infection, indicating that the immune system is fighting off the harmful agents. Abdominal cramps are also typical as the intestines become irritated and inflamed due to infection or foodborne toxins.

This set of symptoms is characteristic of foodborne illnesses, making it essential for food service workers and consumers to recognize these signs in order to address potential outbreaks quickly and effectively.
