2. Unwashed Vegetables
This is a no-brainer that applies to produce from pretty much any country. It’s hard to know how much pesticide was used or what parasites had access to the food before it reached your hands. By all means, wend your way through that farmer’s market and purchase exotic vegetables to try. Just make very sure to wash it thoroughly before consuming in water that you know is clean.
Even residents of Mexico recommend washing produce with a drop of antibacterial liquid before consuming. Lettuce is particularly prone to bacteria like salmonella and listeria and tends to make people sick because it is rarely cooked before eating. To stay healthy, maybe give yourself permission to avoid salads during your trip – hey, you’re on vacation after all.
