Go for sparkling - skip the ice

Unscrupulous restaurant owners have been known to fill up mineral water bottles from the tap and resell them, but it's much harder to do this with sparkling water. In countries where the tap water isn't safe, stick to the sparkling and bottled varieties at all times - and that includes for cleaning teeth. Always make sure the seal is intact.

Ice cubes that melt into your drink and the floating lemon slice are other potential sources of contamination that are essential to avoid. Ask for soft drinks to be opened in front of you, and drunk straight from the bottle or can. That way you know it hasn't been watered down or put in a contaminated glass.
