What are the symptoms of foodborne illness?

The symptoms of foodborne illness commonly include nausea, vomiting, diarrhea, stomach cramps, and fever, which are indicative of the body’s response to harmful microorganisms or toxins consumed through contaminated food or beverages. These symptoms reflect the gastrointestinal distress that can result from infections, such as those caused by bacteria, viruses, or parasites, as well as from certain chemicals or toxins.

In contrast, the other choices encompass symptoms that are not typically associated with foodborne illnesses. Headaches and dizziness may relate to various health issues, but they are not specific indicators of foodborne illness. Fatigue and insomnia predominantly refer to conditions affecting overall wellness rather than direct consequences of consuming contaminated food. Skin rashes and itching are typically symptoms of allergic reactions or dermatitis, not foodborne illnesses. Therefore, option B accurately captures the key symptoms that are consistently associated with foodborne illnesses, making it the correct answer.
