The symptoms of foodborne illnesses primarily include nausea, vomiting, diarrhea, abdominal cramps, and fever. These symptoms arise as the body's reaction to consuming contaminated food or beverages. When food is contaminated with harmful bacteria, viruses, parasites, or chemicals, the body responds by trying to expel the harmful substances, leading to nausea and vomiting. Diarrhea and abdominal cramps are common as the digestive system attempts to rid itself of the pathogens. Fever may also occur as part of the immune system's response to infection, indicating that the body is fighting off the harmful invaders.

Other options mention symptoms that, while they may occur with other illnesses or conditions, are not characteristic of foodborne illnesses. For example, fever and sneezing are typically associated with respiratory illnesses rather than foodborne pathogens. Similarly, muscle pain and fatigue are more generalized symptoms that can result from numerous health issues but do not specifically point to food-related illnesses. Headache and dizziness can also be symptoms of various ailments but do not represent the typical presentation of foodborne illness. Recognizing the correct symptoms is crucial for identifying foodborne illnesses and taking appropriate action for prevention and treatment.
