This is one area where prevention can really pay off. In addition to the precautions above, these steps can help:
Always wash your hands with soap and water before eating. This prevents transferring bacteria or parasites to your food or mouth. Use alcohol gel when you canít wash your hands.
Consider taking Pepto-Bismol (2 tablets, 4 times a day), to prevent travelersí diarrhea if you will be traveling less than 3 weeks in a developing country. Pepto-Bismol may help prevent more than half of all cases of travelersí diarrhea. Pepto-Bismol may cause black stools or a black tongue, which look strange, but are harmless.
