What are common symptoms of a foodborne illness?

The answer highlights diarrhea, abdominal pain, and fever as common symptoms of foodborne illness, which is accurate. These symptoms typically arise due to the body's response to harmful pathogens or toxins ingested with contaminated food. Diarrhea is a common reaction as the body attempts to rid itself of the pathogens, while abdominal pain signifies discomfort and irritation in the gastrointestinal tract. Fever often accompanies infections, reflecting the body’s immune response to fight off illness.

Other symptoms listed in the other options, such as nausea and vomiting, are certainly associated with foodborne illnesses but may not be as prevalent as diarrhea and abdominal pain. Similarly, loss of appetite and stomach cramps are often seen but are not as definitive or universally experienced in foodborne illness scenarios. Shortness of breath and skin rash are not typical symptoms of foodborne illnesses; they are more indicative of allergic reactions or different types of illnesses altogether.
