Traveler's diarrhea and other intestinal infections can affect any traveler.
While it may be tempting, pass on the street food (especially if there is no line for the vendor - this tells you that locals know not to eat there).
Boil, cook, and/or peel foods purchased.
Only eat raw vegetables if they were washed well with clean, hot water.
Always wash your hands with soap before eating, or use hand sanitizer.
If you have a food allergy, always ask the cook or person prepping the food if it contains any of your allergens – especially if you are allergic to peanuts, pine nuts, certain spices, and shellfish.
Water
Drink bottled water. Check the bottle for signs of tampering before drinking, including under the label, the lid, and the bottom of the bottle.
Clean bottles or cans before opening and if they are stored in ice.
Do not use ice in drinks, as ice may not have been made with clean drinking water.
Use safe water for brushing teeth and cleaning fruits and vegetables.
Don’t drink water from rivers or open wells, unless using an iodine resin water purifier.
