2. Canned or bottled carbonated beverages, including carbonated bottled water and soft drinks.

3. Beer and wine: Where water may be contaminated, ice (or containers for drinking) can also be considered contaminated, and it is generally safer to drink directly from the can or bottle of a beverage than from a questionable container. Wet cans or bottles should be dried before being opened, and surfaces that come into direct contact with the mouth should first be wiped clean. If no source of safe drinking water is available, e.g. verifiably safe bottled-water, tap water that is uncomfortably hot to touch may be safe, once it has cooled and put in a thoroughly cleaned container; it can also be used for brushing teeth as well as for drinking.

4. Fresh Fruit and Vegetables: In areas of the world where hygiene and sanitation are known to be poor, to avoid illness, fresh food should always be selected with care. You should avoid unpasteurized milk and milk products, such as cheese, and eat only fruit that you have peeled yourself. You may prepare your own fruit juice from fresh fruit. Iced drinks and non- carbonated bottled fluids from water of uncertain quality should be avoided.

5. Street-food: Many developing (and developed) countries offer an abundance of food sold from stands, along the road. It is advisable to avoid such food unless and until you have ample evidence from reliable local sources that it is safe for visitors to eat. Note: many locals may have no trouble with such food or drink, but this is often because they have developed over time bodily immunities against its possible impurities, which is not the case for visitors.
