Episodes of TD usually begin abruptly, occur during travel or soon after returning home, and are generally self-limited. The medium duration of TD is 3-4 days. Travelers should avoid risky foods such as raw or undercooked meat and seafood and raw fruits and vegetables. Tap water, ice and unpasteurized milk and dairy products are also associated with an increased risk of TD, and thus should be avoided. Travelers should limit their drinks to safe beverages, such as bottled carbonated beverages, beer, wine, hot coffee, tea or water boiled appropriately or treated with iodine or chlorine.
Food eaten from street vendors is considered a higher-risk food than restaurant food.
