You may avoid the water and ice when traveling to exotic locales so you won’t ingest a parasite or illness-causing bacteria. But here’s another thing to steer clear of if you don’t want to spend your vacation worshipping the porcelain God: Raw vegetables! Even in the U.S. and Canada, raw vegetables can be a top source of pathogens because they may be handled by dirty hands, or contain contaminants from soil and water run-off. In fact, the CDC says raw vegetables – like leafy greens – were one of the main sources of food poisoning last year. So if the WATER is sketchy where you’re vacationing, that same sketchy water is being used to grow and wash the vegetables. So order them fully-cooked, so the heat will kill the bacteria.
