Food poisoning is a condition caused by the consumption of contaminated food or beverages. The pathogens involved are usually Staphylococcus aureus, Norovirus, Salmonella, Escherichia coli, campylobacter, and Clostridium perfringens. Severe cases of food poisoning can lead to hepatic, renal, and neurologic symptoms that cause death or permanent disability.
Diagnosis can be achieved via patient history, physical examination, blood tests, stool testing, blood culture, and more. Mild cases of food poisoning usually improve without specific treatment. However, severe cases may require aggressive hydration, antibiotic treatment, and hospitalization.
The main goal of treatment is rehydration and providing electrolyte supplements. Patients should also avoid milk and other dairy products. Medication that may be used include antidiarrheals and antibiotics to prevent food poisoning, it is important to practice good personal hygiene, knowing to cook all foods adequately, avoid cross-contamination of all foods, and keeping various foods at the appropriate temperature. In the United States, the Centers for Disease Control and Prevention (CDC) has estimated that approximately 1 in 6 individuals are affected by food-borne illnesses with 128,000 hospitalized and 3,000 deaths annually.
