Can I Drink Local Water in Mexico?

Water treatment and filtration systems have improved in some parts of Mexico over the years, with many resorts and major tourist spots like Mexico City, Monterrey and Cancun claiming water is safe straight from the tap. It's up to you if you want to take their word and try it. Otherwise, you will need to make sure your water is boiled or treated especially if you are out traveling in rural locations.

It's easy to forget while on vacation the many things cleaned or prepared with water -- ice, salad, pasta, etc. You need to be careful when brushing your pearly whites, too. Even if water is purified, it still might give you diarrhea because you're not used to the microbes swimming around in it.

Montezuma's Revenge

Travel diarrhea aka Montezuma's Revenge can literally put a cramp in your travels and your stomach. However, there are ways you can avoid being stuck riding the porcelain bus by observing good personal hygiene practices and taking precautions with where and what you eat.

Food stalls are common throughout Mexico, even in the rural areas, where families make a living selling homemade cooking. Some food is prepared safely and kept well, but watch out for hot foods that aren't actually hot and anything that looks like it's been sitting uncovered for a while. Always eat at spots where the food is cooked on the spot, has a high turnover and if you eat meat, ask for it to be cooked more on the well done side.

Avoid buffet-style restaurants where the food may be prepared in a questionable way or left to sit out all day. For more handy tips, check out our article on street food safety.

It goes without saying but always wash your hands before eating (use an antibacterial gel if running water and soap isn't available).

If, unfortunately you do end up sick, often it's a case of just riding it out. Read our article on what to do should you end up with a dose of traveler's diarrhea.

    I lived in Mexico for several years. In order for the boiling method to work, water must boil for 20 minutes. Go that reason, coffee and tea should be avoided unless you have confidence that it was boiled sufficiently.

    Turists drink too much, way too much, and when they get sick they blame it on the water! I lived in Puerto Vallarta and Mexico city for 10 years and never got stomach problems. Not a heavy drinker!
