The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) has identified these precautions to keep travelers safe in foreign lands.
- Do not drink any tap water, not even when brushing your teeth.
- Do not drink unpasteurized milk or dairy products.
- Do not use ice made from tap water.
- Avoid all raw fruits and vegetables (including lettuce and fruit salad) unless they can be peeled and you peel them yourself.
- Do not eat raw or rare meat and fish.
- Do not eat meat or shellfish that is not hot when served to you.
- Do not eat food from street vendors.
- It should be safe to drink bottled water (if you are the one to break the seal), carbonated soft drinks, and hot drinks like coffee or tea.
- If you do get Traveler's Diarrhea, the NIDDK recommends trying to wait it out until the diarrhea passes. Using diarrhea medications may cause the bacteria to stay in your system longer.
- Until the Traveler's Diarrhea subsides, try to avoid milk products and foods that are greasy, high-fiber, or very sweet. These foods tend to make the diarrhea worse.
- Avoid dehydration by eating plenty of broth and soups. Water doesn't have enough electrolytes to replace what's being lost. By all means, drink when you are thirsty, but also eat a balanced diet.
- Depending on where you are going and how long you are staying, your doctor may recommend that you take antibiotics before leaving to protect you from possible infection.
