Most people are aware that drinking water in foreign places can likely cause water-borne illnesses ( you’ve heard of Montezuma’s Revenge?) because you might not have adapted to the water the way that folks local to an area have. So we know not to drink the local water unless you can boil it or have those little pills that would purify the water and to ask for bottled water. But there might be other areas to watch out for that might not be so obvious.

If you can’t drink the water, you probably shouldn’t use it to brush your teeth either. I also wonder about ice cubes. Would there be any risk to having iced drinks? What about fresh fruit and veggies? Would they be washed in local water? Seems like there might be some risk there too. Anyone have any thoughts or information on this?

I figured I would hop on over to CDC to see if I could find out anything more definitive. There is a handy pdf there “A Guide to Drinking Water Treatment and Sanitation for Backcountry and Travel Use”.
