What are common symptoms of foodborne illness?

Nausea, vomiting, diarrhea, abdominal pain, and fever are indeed common symptoms of foodborne illness. These symptoms typically arise as the body reacts to pathogenic microorganisms or toxins present in contaminated food or beverages. The gastrointestinal system is primarily affected because it is where most foodborne pathogens proliferate and cause harm. Nausea and vomiting are protective mechanisms to expel harmful substances, while diarrhea often results from the body's attempt to remove pathogens rapidly. Abdominal pain can occur due to intestinal inflammation or irritation, and fever is a common systemic response indicating that the body is fighting off an infection.

The other options describe symptoms associated with different health issues or conditions that are not specifically tied to foodborne illnesses. Headache, dizziness, and fatigue can stem from various causes including dehydration, stress, or illnesses unrelated to food. Skin rash and redness are usually associated with allergic reactions or dermatological conditions rather than food factors. Memory loss and confusion could point to neurological issues but are not common indicators of foodborne infections. Understanding these distinctions is important in identifying and managing food safety and health risks effectively.
